INSTRUCTION MANUAL

1. Always make sure to insert the plug of test leads fully into the terminal

of the instrument.

2. Never exceed the maximum allowable input of any measuring range

when making measurement.

3. Make sure to never apply a voltage more than 600V AC or DC between

the terminal of the instrument and earth.

4. Never tr y to operate the instrument in

an explosive atmosphere ( i. e.

in the presence of flammable gases or fumes, vapor or dust).

5. Always inspect the instrument, test leads and accessories for any sign

of damage or abnormality before every use. If abnormal conditions

exist (e. g. broken test leads, cracked enclosure of the instrument), do

not try to make measurements.

6. Do not push the test button or lock it down while connect

ing test leads.

7. Do not touch the circuit under test during insulation testing.

8. Make sure to remove the test lead from the instrument and turn the

10. Do not expose the instrument to the direct sun, dew fall, or extreme

temperatures.

11. Do not expose the instrument to

a temperature of more than 50 .℃

12. Calibration and repair of any instrument should only be performed by

qualified and trained service technicians.

13. Do not install substitute par ts or per for m any unauthori zed

1. Safety Precautions

● This instruction manual contains warnings and safety rules that must

be observed by the user to ensure safe operation of the instrument and

retain it in safe condition. Therefore, read these operating instructions

thoroughly and completely before using the instrument.

● The symbol on the instrument means that the user must refer to #

the relevant section of this instruction

manual for safe operation of the

instrument.

● Pay particular attention to all WARNINGS and CAUTIONS in this

instruction manual. WARNING indicates warnings to avoid electrical

shock and CAUTION indicates cautions to avoid damage to the

instrument.

the

∞

mark on the red megaohm scale. If not, adjust it by rotating

the meter movement zero adjust with a screwdriver.

（）2 Test lead connection

Insert t

he test leads into the terminals of the instrument.

（）3 Battery voltage check

Battery check LED flashes at insulation resistance testing to indicate

normal battery condition.

Replace the batteries when the LED stops flashing.

Replace the batteries according to section 6 for battery replacement.

（）4 Test leads check

Press and turn the Test button to lock it down. When the test leads

are connected together,

the pointer should move from the position ∞

towards the 0 position on the megaohm scale. If not, the leads may be

faulty. Release the Test button after completion.

# WARNING

When the Test button is pressed, take care not to touch the tip of the

test lead where a high voltage is present in order to avoid possible

shock hazard.

4-2 AC Voltage Warning Function

# WARNIING

Never depress the test button whe

n voltage is present on the circuit

under test.

（）1 The presence of AC voltage can be detected. This function operates

automatically when the test button is not depressed, i.e., in the up

position.

（）2 Using the test leads, connect EARTH terminal to the earth side of the

circuit under test and LINE terminal to the line side.

（）3 Take the reading on the AC voltage scale.

4-3 Insulation Resistance Measurement

# WARNING

To avoid electrical shock, do not touch the test lead tips and the

circuit under test during measurement.

# CAUTION

To avoid damage to the instrument, insulation measurement must be

performed on de-energized circuits only. Make sure that the circuits

or equipment is disconnected before proceeding with an insulation

test.

（）1 Connect the test leads to the instrument and the circuit under test.

（）2 Check the circuit under test is not energized as follows.

Connect the test leads to the circuit under test and read a voltage

value.

If the circuit is live, the meter indicates the voltage.

If the meter indicates 0V, the circuit is dead.

（）3 Press test button. Read the red megaohm scale directly.

● Continuous Measurement

A lock down feature is incorporated on the test button. Pressing and

turning it clockwise lock the test button in the continuous operating

position.

To release the lock turn the test button counter clockwise.

Never leave the test button locked down when not in use.

（）4 Discharging capacitance of circuit under test.

It is possible that capacitance has been stored in the circuit under test

after insulation testing. To discharge th

e circuit capacitance reverse

the connection of the earth clip and line probe. Remaining electric

charges can be observed on AC voltage warning range.

# WARNING

Do not touch the circuit under test immediately after testing.

Capacitance stored in the circuit may cause electric shock.

5. Battery Replacement

# WARNING

Ｔo avoid shock hazard disconnect the test leads from the

instrument.

To replace the batteries, first disconnect all test leads from the instrument.

Open the battery compar tment cover by unscrewing the metal captive

screw to reveal batter y compar tment. The four 1.5V SUM-3(R6)type

batteries are located in a compartment. Always replace all four batteries

with new

ones at the same time. Never mix old and new ones. Screw the

battery compartment lid back on before using the instrument.

6. Notes on Housing Case & Accessories

6-1 Case Lid

Case lid can be fit under the housing case as illustrated bellow.

1) Open the case lid as shown.

2) Turn it 180 degrees.

Put the case lid under the housing case.

4) Hook it on to the housing case.

6-2 How to fit Neck Strap & Test lead Pouch

1. Fit the neck strap as shown.

2. Fit the test lead pouch to the housing case as shown.

7. Servicing & Calibration

If this tester should fail to operate correctly. return to your distributor,

stating exact nature of fault. Make sure that:-

a. Operating instructions have been followed

b. Leads have been inspected

c. Batteries have been checked

d. The unit is returned with all accessory leads

Note : Since the meter cover has been given an anti-static treatment do not

rub it strongly with dr

y cloth to remove dust or dirt. If electrostatic

charges are present on the cover. wipe it with a soft cloth wet with

anti-static solution.
