EM305A – CLAMP MULTIMETER

Before you start using EM305A clamp multimeter read carefully this

Instruction Manual.

There are highlighted important selected passages which deal with the

occupational safety of this device. This is the way how to avoid electrical

accidents or damage to this device.

The clamp multimeter was designed in compliance with IEC-61010 related

to electronic measuring equipment falling into the category (CAT III 600V),

safety class II and pollution level 2.

equipment is protected by double insulation and reinforced

insulation

WARNING

Pay close attention to the following instructions:

• Before you start using the multimeter check carefully the device for

damage. In case you nd evident damage, do not make any measure-

ments! Check the surface for scratches and unglued side joints.

• Check insulation on measuring probes and jaws. When the insulation

is damaged the risk of electric shock may occur. Do not use damaged

measuring probes and jaws!

• Do not measure voltage higher than 600 Vor current higher than 600A!

• Clamp “COM“ must be connected to the reference measuring earth.

• If you nd out abnormal measurement results, do not use the mul-

timeter. In case you are not sure about the cause of fault, contact the

service centre.

• Do not measure higher voltage and current values than those which

are marked on the front panel of the multimeter and jaws. There is arisk

of electric shock and damage to the multimeter!

• Before the use verify the right function of the multimeter. Test the circuit

of which you know the electric parameters.

• Before you connect the multimeter to the circuit for which you want

to measure current, switch o supply of the given circuit.

• Do not use and store the multimeter in the space with high temperature,

dustiness and humidity. We also do not recommend using the device

where strong magnetic eld occurs or where the risk of explosion or

re occurs.

• When replacing the battery or other parts of the multimeter, use spare

parts of the same type and specication. Replace the parts only when

the multimeter is o and disconnected!

• Do not change or modify the inner circuits of the multimenter in any

way!

• Pay close attention to measurement of voltage higher than 30 VACrms,

peak 42 Vor 60 VDC. There is arisk of electrical injury!

• When handling the measuring tips, make sure you hold them behind

the nger barrier.

• To avoid electrical injury do not touch any bare conductors with your

hand or skin.

• Before you open the multimeter cover, disconnect the measuring tips

from the tested circuit.

• Do not make measurements when the multimeter cover is removed

or loose.

• As soon as the at battery icon appears “ “, replace the battery.

Otherwise the performed measurements can be inaccurate.

CATIII – measurement category III is designated for measurements of

house installation.

The example are measurements of distributions, circuit breakers, electric

installations, including cables, busbars, connection boxes, switches, sock-

ets, equipment for industrial use and some other equipment as stationary

engines with permanent connection to the xed installation. Do not use

the device for measuring in category IV.

WARNING

Use the multimeter EM305A only in the way specied below, otherwise

damage to the device or your health can occur. Pay attention to the

following instructions:

• Before you measure resistance, diodes or current, disconnect the circuits

from the power supply and discharge high-voltage condensers.

• Before measuring, make sure that acircular switch of the measurement

range is in the right position. Do not make any changes in the measure-

ment range during the measuring process (indexing the circular switch

of measuring programmes) in any case! It could result in damage to

the device.

• If you measure current, switch o the circuit supply before connecting

the multimeter.

Device Description

The clamp multimeter EM305A is of the range of compact devices with a3.5

digital display designated for the measurement of direct and alternating

voltage, alternating current, resistance, diode testing and sound tests of

conductivity and circuits.

The multimetr is equipped with an automatic range for measuring values.

It indicates exceeding the measured range. It has an automatic break

function. The multimeter provides an overload protection and informs

on the battery low conditions.

The multimeter EM305A is suitable for using e.g. in workshops, laboratories

and households.

1. Jaws

They are used for enclosing aconductor when measuring the current.

2. FUNC./HOLD button (holding data on the display)

It is used for entering the mode for holding measuring data or n-

ishing this mode (it applies to measurement of voltage, current and

resistance). It is used for switching between adiode test or continuity

test when arotary switch is in position.
