1 Introduction

We appreciate your having purchased our digital clamp AC

leakage current tester. The CMP-200 meter is a modern, high-

quality measuring device, which is easy and safe to use. Please

acquaint yourself with the present manual in order to avoid

measuring errors and prevent possible problems related to

operation of the tester.

In the present manual we apply three kinds of warnings. These

are texts in frames, which describe possible dangers both for the

user and the tester itself. The messages starting from the word

‘WARNING:’ describe situations which imply a risk for life or health

should the recommendations presented in the present manual not

be observed. The word ‘ATTENTION!’ introduces a description of a

situation where non-observance of the recommendations presented

in the present manual may imply damage for the tester. Indications

of possible problems are preceded by the word ‘Attention:’.

WARNING:

Before using the instrument acquaint yourself with the

present manual and observe the safety regulations and

recommendations specified by the manufacturer.

WARNING:

The purpose of the CMP-200 tester is to realise clamp

measurements of the leakage current. Using the tester in a

manner which does not comply with the recommendations

specified in the present manual may lead to its damage and

constitutes a source of a serious risk for the user.

WARNING:

The CMP-200 tester may be operated solely by qualified and

properly authorised personnel for work at electric

installations. Using the tester by unauthorised personnel

may lead to its damage and constitutes a source of a serious

risk for the user.

2 Safety

In order to guarantee proper operation and correctness of the

obtained results it is necessary to observe the following

recommendations:

•Before commencing operation of the tester please acquaint

yourself thoroughly with the present manual,

•The instrument should be operated solely by properly qualified

personnel, who also must be trained regarding the industrial

safety regulations,

•Use great care when making measurements if the voltages are

greater than 25V AC rms or 35V DC. These voltages are consi-

dered a shock hazard,

•Set function switch to the appropriate position before

measuring,

•Do not exceed the maximum allowable input range,

•It is prohibited to operated the tester:

⇒If it is damaged and completely or partially out of order

⇒If it has been stored for an excessive period of time in

inadequate conditions (e.g. if it is humid)

•Repairs must be realised solely by an authorised service

workshop

WARNING:

Do not realise measurements with wet hands.

WARNING:

Do not realise measurements in environments in which there

are inflammable gases. Otherwise operation of the tester

under such conditions may cause sparking and explosion.

3 Preparation of the tester for operation

Having purchased the tester examine completeness of the

contents of the package.

Before measurements commence, it is necessary to realise the

following actions:

•Make sure the conditions of the batteries or accumulators

permit to realise measurements,

•Make sure the casing of the tester is not damaged.

5 Measurements

5.1 AC current measurements

WARNING:

Do not take current readings on circuits where the maximum

current potential is not known. Do not exceed the maximum

allowable input range while measuring current.

WARNING:

Do not realise measurements if the battery compartment is

open.

In order to realise a measurement of alternative current, it is

necessary to realise the following actions:

•Set the Function switch to desired range, if the range of the

measured is not known, select the highest range first,

•open the clamp and place it properly on a cable

•read the result of the measurement on the display,

•move to the lower range if necessary.

Attention:

During measurements of the current make sure the clamp is

properly placed. Otherwise the results of the measurements

will not be exact. The most exact result we will get if the wire

is placed in the middle of clamp.

Refer to the diagrams below for examples of the tester’s

applications

5.2 DATA HOLD Function

To freeze the LCD tester reading, press the HOLD button. The

word HOLD will appear on the LCD while the tester is in the Data

Hold mode. To release the Data Hold function and return the tester

to normal operation, press the “Hold Backlight” key again. The word

HOLD will switch off.

5.3 Backlight display

Press and hold the HOLD button key for more than 2 seconds

to turn on the backlight. This will also activate the Data Hold

function. To release the Data Hold function and return the tester to

normal operation, press the HOLD button momentarily. To turn off

the backlight, press and hold the HOLD button for more than 2

seconds.

5.4 DATA MAX HOLD Function

To freeze the max reading on the LCD, press the MAX button.

The word MAX will appear on the LCD while the tester is in the Max

hold mode. To release the tester to normal operation, press the

MAX button.
