AC CLAMP METER

CMP-400

Version 1.6

The CMP-400 digital clamp meter has been designed for the

purpose of clamp measurements of alternative current.

Furthermore, the meter may be used to measure direct and al-

ternative voltages, resistance, frequency, temperature and to test

diodes.

Main features of the CMP-400 device are the following:

•automatic or manual regulation of the measurement range,

•DATA HOLD function, which facilitates readings of measure-

ments in the case of insufficient lighting or in inaccessible plac-

es,

•ZERO function, which allows you to make measurements rela-

tive to a stored reference value,

•the function of automatic switching of the meter into the standby

mode in order to prolong the durability of batteries,

•circuit continuity sound signalling (Beeper),

•3 ¾ digits display,

•safe, protected clamp jaws,

•double molded housing.

1 Introduction

We appreciate your having purchased our digital clamp meter.

The CMP-400 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 meter.

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 meter 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 meter. Indications

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

WARNING:

Before using the instrument acquaint yourself with the pre-

sent manual and observe the safety regulations and recom-

mendations specified by the manufacturer.

WARNING:

The purpose of the CMP-400 meter is to realise measure-

ments of the current, directs and alternative voltages, re-

sistance, frequency, temperature and diode testing. Using

the meter in a manner which does not comply with the rec-

ommendations specified in the present manual may lead to

its damage and constitutes a source of a serious risk for the

user.

WARNING:

The CMP-400 meter may be operated solely by qualified and

properly authorised personnel for work at electric installa-

tions. Using the meter 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 recommen-

dations:

•Before commencing operation of the meter 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,

•Before use for non-contact AC voltage measurements, always

test the voltage detector on a known live circuit to verify proper

operation,

•Set function switch to the appropriate position before measur-

ing,

•When measuring volts do not switch to current/resistance

modes,

•Do not exceed the maximum allowable input range of any func-

tion,

•Do not apply voltage to meter when resistance function is se-

lected,

•When changing ranges using the selector switch always dis-

connect the test leads from the circuit under test,

•Do not exceed the maximum rated input limits,

•It is prohibited to operated the meter:

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

⇒If the insulation of the test leads has been damaged

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

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

•Repairs must be realised solely by an authorised service work-

shop

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 meter

under such conditions may cause sparking and explosion.

ATTENTION!

2.1 International Safety Symbols

This symbol, adjacent to another symbol or terminal, indi-

cates the user must refer to the manual for further infor-

mation.

This symbol, adjacent to a terminal, indicates that, under

normal use, hazardous voltages may be present

Double insulation

3 Preparation of the meter for operation

Having purchased the meter examine completeness of the con-

tents of the package.

Before measurements commence, it is necessary to realise the

following actions:

•Make sure the conditions of the batteries or accumulators per-

mit to realise measurements,

•Make sure the casing of the meter and the insulation of the test

leads are not damaged.

WARNING:

Connection of inappropriate or damaged test leads consti-

tutes a risk of an electric shock with a dangerous voltage.
