GT-650/GT-900 User's Manual

Preparation of the GT-650/GT-900 Tester

Turning on the GT-650/GT-900 tester

1) Connect the GT-650/GT-900 tester to a correctly installed Schuko mains

socket.

2) Use the mains switch “ON/OFF“ (4) to turn on the GT-650/GT-900 tester.

3) After turning on the GT-650/GT-900 tester, pilot lamp of the power switch

(4) will switch on and the display (17) will show idle readout of selected

function. The GT-650/GT-900 tester is now ready for use.

Test lead compensation

The GT-650/GT-900 tester leaves the factory with uncompensated test lead in RPE

function and uncompensated test adapter in CORD/PRCD function. We recommend

to compensate test lead/adapter before starting the R

PE, CORD or PRCD tests,

otherwise result may not be correct There are two compensations available (two

independent compensation values).

 Compensation of test lead when carrying out R

PE measurements (single

measurements or AUTO-TESTS). Warning note “TEST LEAD NOT

COMPENSATED” will be displayed for a moment after pressing the “START”

key as long no test lead is compensated or compensation value was deleted.

 Compensation of test adapter when carrying out CORD measurements (CORD

on reel only) or PRCD measurements (single measurements or AUTO-TESTS).

Take care when test adapter is to be compensated, there will be no warning if

test adapter is not compensated.

Procedure for compensation in RPE measurements:

1) Set the measurement function selector (6) to RPE position.

2) Connect test lead, which will be used later on to perform the RPE

measurement, according to the figure below.

3) Press the “COMP” menu key (F2), then start the measurement by pressing

the “START” button (7). Pilot lamp “ON” (8) indicates the active

measurement, then the result using uncompensated test lead is displayed

for a moment. Another regular measurement is done automatically using

compensated test lead, now the result should be nearly zero. In the upper

display line the character “C“ (compensated) appears as the information

that test lead is compensated.

Figure 7: Connection for test lead compensation

GT-650/GT-900 User's Manual

☞ This compensation will be used in all further single or AUTO-TEST RPE

measurements. It will be active even after switching off and on the GT-

650/GT-900 tester.

☞ CORD and PRCD functions are using their own compensation (the same

for both functions) independent from above described one. See the

information on how to compensate/uncompensated test adapter in

chapters “IEC CORD Test (CORD/PRCD)“ starting on page 39 and “PRCD

Test (CORD/PRCD) (GT-900 only)” starting on page 43”.

☞ Whenever test lead or adapter is changed, the compensation has to be

redone. Wrong compensation will direct influence the test result and may

give wrong judgement for limit.

☞ Compensation is always carried out using test current of 5 A, while second

measurement (self-test) is using selected test current (0.2 or 5.0 A).

How to cancel actual test lead compensation:

Open test loop (disconnect test lead from terminal PROBE 2) and carry out the

compensation as described above. The result >11.00 will be displayed and “C”

symbol will disappear from the top display line.

Limit value setting

Limit value is offered in all functions except in P/IL and CLAMP (range 0 … 60 A).

For limit value setting press the “LIM” (or “PAR”, see explanation in each function

separately) menu key, then use the menu keys “+”, “–“, “STD” (Standard) or

“CALC” (Calculation). The menu key F8 “EXIT” can be used to exit limit value

setting display.

☞ In case test result comply with set limit value, the symbol “ ” is displayed and

two short sound signals are present after finishing the measurement. In case

of non-compliance, the symbol “X” is displayed and one longer sound signal is

present after finishing the measurement (see the details in chapter

“ACOUSTIC SIGNAL” on page 77). The limit value is saved as a parameter of

the measurement result and is transferred to PC in case of data transfer.

Start of the measurement

 For single measurement press the START key and release it. In this case

measurement time is defined in MENU / SETUP / MEASUREMENT TIMES menu,

see the chapter “SETUP menu” on page 76. Watch elapsed time on displayed bar

graph during the measurement.

 For continuous measurements press and keep pressing the START key for at least

2 seconds until “CONT” (continuous) information is displayed. Measurement

time is limited to 5 minutes maximum in this case. Continuous measurement is

available in all functions except in CORD, PRCD and AUTO-TESTS.

GT-650/GT-900 User's Manual

External Voltage Display

 If there is a dangerous external voltage present on test terminals prior to a test

or during it, the warning message “EXTERNAL VOLTAGE!“ will appear on the

display and the start of the measurement will be blocked. Remove the external

voltage!

 If an external voltage is applied to test terminals during the test in RINS function,

wrong measurement values may be displayed.

WARNINGS

 Before starting the tests, you must familiarize yourself with the DIN VDE 0701-

0702 "Testing after repairs, alteration of electrical equipment - re-testing of

electrical devices".

 Before commencing the tests, you are strongly advised to make reference to the

local regulations and standards for safety at works regulations and any relevant

publications from the Health and Safety Executive.

 The DUT (Device Under Test = Appliance) must be switched on for all tests

(mains switch must be turned ON even if the DUT is disconnected from mains

voltage e.g. in RPE, RINS and ISUB tests).

 When conducting tests do not touch the DUT as some tests involve higher

voltages and higher currents.

 Do not touch the test specimen during the measurements, as a high risk may

arise in the case of faulty test specimens.

 The tests should only be performed by competent persons who are familiar with

the requirements of the type of tests suitable for portable appliances.

 It is potentially hazardous for both, user and the DUT if the wrong type of tests

be undertaken or if testing is carried out in an incorrect sequence.

 It is important that you fully understand the various tests required and how they

should be performed.

 The appliance must have passed the visual inspection, the protective earth bond

resistance test (PC I appliances) and the insulation test (in this sequence) prior to

any other test. If any of these tests fail further testing must be stopped and any

faults must be fixed.

 During the earth leakage current test (IPE()), the touch leakage current test (IT)

and the function test (load power/current (P/IL)), the DUT will be energized at

mains voltage. For this purpose, switch on the DUT. DUT driven by motors or

equipped with heating elements may present a danger for the person testing or

others (comply with the user’s manual of the DUT!). Please ensure that the DUT

is in a safe condition to run and secure prior to testing.

Insulation Resistance Test 250 V / 500 V (RINS)

The insulation resistance test measures the resistance of the insulation between:

 L/N terminals of test socket and PE terminal of test socket in parallel with

PROBE 2 (at PC I, PC I-HEATER (with heater) and PC II). L/N terminals are shorted

by the GT-650/GT-900 tester for this test.

 Test probe PROBE 1 and test probe PROBE 2 (at PC III).

Warnings

 The test voltage is either 500 V (or 250 Vd.c. at GT-900 only). Do not touch

the appliance during the insulation test! If the test fails, any metal part of

the appliance could become live!

 Always make sure that the test has completed before disconnecting the

appliance leads to ensure that all capacitances have discharged!

Cautions

 Do not perform the Insulation test on appliances that failed the protective

earth bond test or the visual inspection test.

 Please ensure that the mains switch of the appliance is closed.

 The insulation test may not be suitable for some types of appliances (i.e.

electronic devices or IT-devices). For these appliances an alternative test

may be conducted such as touch leakage current, earth leakage current or

substitute leakage current test. It is essential to refer to the local appliance

test standards and/or reference material for the safe applicability of these

alternative tests.

 Test voltage of 500 V may not be suitable for some appliances that contain

overvoltage protection devices (e.g. varistors) in their input circuits. For

these appliances test voltage of 250 V shall be used, refer to the local

appliance test standards and/or follow the manufacturer

recommendations.

Test procedure and instructions:

 Connect the appliance and the test lead according to one of the figures 12, 13,

14 or 15, depending on appliance protection class (PC).

 For PC I appliances no probe is required except if there are some conductive

parts on the appliance which are not connected to PE terminal. In this case use

probe 2 in addition.

 For PC II appliances apply the test probe to any exposed conductive part on the

appliance. Do the test for all exposed conductive parts on the appliance, partial

results must pass pre-set limit value. Use therefore probe 2.

Note!

Modified set of test steps (some steps added or deleted) can be reached by creating

a new PRCD AUTO-TEST. There are two ways to create new PRCD AUTO-TEST:

 To copy one of existing factory-programmed PRCD AUTO-TESTS (410 … 413) to

a new AUTO-TEST location (500 … 999) and then to modify it freely, see the

sections “COPY AUTO-TEST” on page 74 and “EDIT/VIEW AUTO-TEST” on page

71.

 To create new AUTO-TEST from scratch like any other AUTO-TEST. See the

instructions for creating new AUTO-TEST in section “CREATE AUTO-TEST” on

page 72.

GT-650/GT-900 User's Manual

Description of test steps (all available test steps are described below, please

see the table above which test steps are implemented depending on selected

PRCD type):

 Visual inspection

Follow the instructions in section “Visual inspection” on page 20. Confirm pass

of the visual test by the “OK” menu key.

 Protective earth continuity RPE

The measurement is carried out by using the test current of 0.2 or 5.0 A

(selectable parameter). Limit value is adjustable from 0.01 to 11.0 . Both

parameters (test current and limit value) can be set by using the “PAR” menu

key in idle display mode. Limit value can be also calculated on bases of entered

cross section and length of the PRCD cable. In order to enter the limit value

with "+" and "-" menu keys directly without calculation, press the " "

menu key first.

 Insulation resistance RINS input

The insulation resistance is measured on the input side of the PRCD by using

test voltage of 500 V (fixed parameter). Limit value for RINS is fixed and pre-set

to 0.15 M.

 Insulation resistance RINS output

The insulation resistance is measured on the output side of the PRCD at open

PRCD switch by using test voltage of 500 V (fixed parameter). The limit value

for RINS is fixed and pre-set to 1.00 M.

 Earth leakage current IPE (differential method)

The measurement is done at closed PRCD switch in two steps (two mains

voltage polarities). The polarity is exchanged automatically. Limit value for IPE

is fixed and pre-set to 3.50 mA.

 Touch leakage current IT (direct method)

The measurement is done at closed PRCD switch in two steps (two mains

voltage polarities). The polarity is exchanged automatically. Limit value for IT is

fixed and pre-set to 0.50 mA. While this test all conductive parts which are not

connected to PE of the PRCD must be tested, the worst one has to be saved.

Note: The ON button would be such a conductive part.

 Functionality of the TEST button (TEST SWITCH)

After pressing the TEST button of the PRCD, both L and N conductors must be

switched off from mains by the PRCD switch. The test result is displayed as PASS

or FAIL.

 Trip out time at IN/2, AC current

Test current is AC.

PRCD must not trip at this current, max. measurement time/range is 300 ms

 Trip out time at IN, AC current

Test current is AC.

PRCD must trip within 300 ms (200 ms for PRCD-S+).

 Trip out time at IN/2, +pulsed current

Test current is positive pulsed (required for A type of PRCD).

PRCD must not trip at this current, max. measurement time/range is 300 ms.

 Trip out time at IN, +pulsed current

Test current is positive pulsed (required for A type of PRCD).

PRCD must trip within 300 ms (200 ms for PRCD-S+).

GT-650/GT-900 User's Manual

 Trip out time at IN/2, -pulsed current

Test current is negative pulsed (required for A type of PRCD).

PRCD must not trip at this current, max. measurement time/range is 300 ms.

 Trip out time at IN, -pulsed current

Test current is negative pulsed (required for A type of PRCD).

PRCD must trip within 300 ms (200 ms for PRCD-S+).

 Tripping current I

The test is carried out by using a ramp current starting at 0.5 IN and increasing

the test current by 0.05×IN per step up to 1.1 IN. There are 13 test steps,

duration 300 ms per step, pause duration is 30 ms.

PRCD must trip within (0.5 … 1) IN.

 Trip out time t at tripping current I

The test is done in previous step, limit value is 300 ms (200 ms for PRCD-S+).

 Functional test at L disconnection (L-TEST/L-TEST S+)

The GT-900 disconnects input L terminal, then both L and N conductors must be

switched off from mains by the PRCD switch, reactivation by pressing the PRCD

ON button must be disabled and there must be no self-reactivation after

returning L. The test result is displayed as PASS or FAIL.

 Functional test at N disconnection (N-TEST/N-TEST S+)

The GT-900 disconnects input N terminal, then both L and N conductors must

be switched off from mains by the PRCD switch, reactivation by pressing the

PRCD ON button must be disabled and there must be no self-reactivation after

returning N. The test result is displayed as PASS or FAIL.

 Functional test at PE disconnection (PE-OFF TEST)

The GT-900 disconnects input PE terminal, then both L and N conductors must

be switched off from mains by the PRCD switch and reactivation by pressing

the PRCD ON button must be disabled. The test result is displayed as PASS or

FAIL.

 Varistor test

The test is done by measuring varistor voltage at 1 mA. The test is considered

to PASS if varistor voltage is within 15 … 25 V.

 Voltage at PE test (VOLT. ON PE)

An operator applies an external test voltage via a safety network into PE of

tested PRCD by pressing the “UPE” button on PRCD-Adapter, then the GT-900

disconnects PE connection of mains socket.

ATTENTION: All to PE connected parts are potentially hazardous while

performing this test. Don't touch PE (input or output) of the PRCD or any metal

or conductive part of the PRCD.

PRCD must trip and reactivation by pressing the PRCD ON button must be

disabled.

 Voltage at PRCD ON button (VOLT. SENSOR/PROBE)

An operator applies an external test voltage via a safety network to ON button

of PRCD under test by using test probe 3 of PRCD-Adapter (simulation of phase

tester), PRCD must trip.

ATTENTION: Don’t touch test probe of probe 3 while performing this test as

this probe is potentially hazardous and it may influence the test result.

Note!

Before performing PRCD test you have to plug PRCD Adapter to test / mains socket

of the GT-900 tester and run a compensation including test adapter.

GT-650/GT-900 User's Manual

Compensation of PRCD Adapter’s internal resistance:

 To obtain correct protective conductor resistance result you must have

compensated (zeroed) the internal resistance of both adapters, see the

connection information below in picture 36. Connect test adapter (=IEC cord)

to test / mains socket of the PRCD adapter and to Test Connector PRCD of the

GT-900 tester.

 Press the “COMP” menu key, then press “START” key. Compensation will be

automatically done and an additional measurement will be carried out to check

effectiveness of performed compensation, result 0.00  should be displayed.

Now the GT-900 tester and PRCD adapter are ready for further use.

Figure 36: Connection of the PRCD Adapter for compensation purpose

Cancel actual PRCD Adapter compensation:

Remove any cable from IEC connector (14) and carry out the compensation.

Result >11.00 will be displayed and “C” symbol will disappear from the top

display line.

Test procedure and instructions:

 Connect the PRCD according to one of the figures 37, 38, 39 or 40 below,

depending on type of the PRCD under test. Use PRCD-Adapter and test adapter

for any type of PRCD.

 Select appropriate nominal differential current by using the “I

N“ menu key

(10 or 30 mA).

 Select appropriate test current (0.2 or 5.0 A) and adjust limit value (0.01 …

11.00 ) in RPE step by using the “PAR” menu key.

 During the measurement of protective conductor resistance flex the flexible

cord along its length to help find any broken conductors or poor connection

joints.

Notes!

 AUTO-TEST names (see the header in each table above) are default names and

can be freely changed by an operator. Max. 11 characters are available for new

name.

 AUTO-TEST codes (TC#) 500 up to 999 are reserved for customer-created AUTO-

TESTS.

GT-650/GT-900 User's Manual

How to create new (customer-created) AUTO-TEST, see also chapter “CREATE

AUTO-TEST” on page 72:

There are two ways

 To create new AUTO-TEST from scratch step by step or

 To copy one of existing AUTO-TESTS to a new location and then modify it.

Note!

When new AUTO-TEST is created regardless of selected region, it will be offered in

both regions.

AUTO-TEST modes

There are two AUTO-TEST modes available:

 STANDARD mode

This mode is advised to be used when operator is starting with AUTO-TESTS in

generally in order to easily follow the AUTO-TEST procedure step by step. Each

new measurement has to be started with START button. Once the operator is

familiar with AUTO-TESTS, FAST mode is advised to be used.

 FAST mode

This mode enables the operator to carry out AUTO-TEST quickly. The whole

AUTO-TEST procedure will be carried out automatically.

How to select AUTO-TEST mode:

See the description in section “AUTO-TEST MODE” on page 78.

REGION:

Select the region before starting with AUTO-TESTS. Region to be selected depends

on the country where the GT-650/GT900 tester is to be used, see more in SETUP /

REGION menu on page 76.

Compensation of test leads in RPE, RPE CORD and RPE PRCD test steps:

When carrying out AUTO-TESTS it is important to be aware that compensations

from single measurements are used in AUTO-TESTS too.

 Currently active compensation in single RPE function is used in RPE AUTO-TEST

steps.

 Currently active compensation in single CORD or PRCD functions is used in

CORD and PRCD AUTO-TEST steps.

After pressing the “TODO” menu key desired appliance codes* to be

tested can be selected. Use the “EXIT” function key to exit TODO

mode.

3 ...... “NEW” menu key, to create/enter new appliance code*.

Note! Each appliance code must be unique under the same client (two

equal appliance codes are not allowed, the GT-650/GT-900 tester

will block double entering the same appliance code).

4 ...... “SEL” menu key, to display list of all appliance codes* (no appliance root is

entered) or just a list of appliance codes* containing entered root

(appliance root is entered). Wished appliance root can be entered after

changing the selection of menu keys by pressing the “ ” menu key.

5 ...... Window reserved for displaying the first three of all appliance codes*

(no appliance root is entered) or just the first three of appliance codes*

containing entered root (appliance root is entered). These Appliance

6 ...... Window reserved for displaying the number of all appliance codes* in

database or for displaying the number of only not tested appliances*, if

“TODO” mode is used.

Notes!

 In both cases (TODO mode used or TODO mode not used) the number in

window 6 depends also on entered appliance root. If no appliance root is

entered, then number of all appliance codes* will be displayed.

 If there are no appliance codes* in database yet (= empty), then keys

“TODO” and “SEL” will not be offered.

 Explanation of the star sign (*) used in this manual:

Parameters/expressions marked with the * sign refer to selected client

code only (client code is selected in MENU / CLIENT menu) or to all client

codes in database (client code is disabled – FILTER DISABLED is displayed in

MENU / CLIENT menu), see the section “CLIENT menu” on page 70.

Test procedure for AUTO-TEST standard way in STANDARD mode:

Standard way means that an appliance code* with belonging attributes is

selected/entered before starting the AUTO-TEST as offered on the display.

STANDARD mode means that test steps are done one after another with manual

start (START key) of each step.

STEP 1

As shown in the figure 46 above, the first step in AUTO function is to select an

appliance code where the AUTO-TEST will be carried out.

PE, CORD or PRCD test. This fuse blows for example if test points are

connected to mains voltage during the test by mistake.

To replace the blown fuse, proceed as follows:

1) Unscrew corresponding fuse holder cap (1, 2 or 10) by using an

appropriate screwdriver.

2) Remove the defective fuse and replace it with a new one (use only

specified fuse as defined in technical specification).

3) Replace the fuse holder cap.

☞ If any fuse blows several times (for example in case of operating

error) the instrument must be sent in to the service department in

order to be checked.

☞ Use only fuses as defined in technical specification. Using alternative fuses

may cause a safety risk!
