MANUAL

CAUTION:
* Before attempting to insert transistors capacitor thermocouple for testing, always be sure
that test lest leads have been disconnected from any measurement circuits.
* Components should not be connected to the hFE and capacitor and the thermocouple
socket when making voltage measure with test leads.
*Using this appliance in an environment with a strong radiated radio – frequency
electromagnetic field (approximately 3V/m), may influence its measuring accuracy. The
measuring result can be strongly deviating from the actual value.

1. SAFETY INFORMATIONS
This multimeter has been designed according to IEC-1010 concerning electronic measuring

instruments with an overvoltage category (CATⅡ) and pollution 2.
Follow all safety and operating instructions to ensure that meter is used safely and is kept in
good operating condition.

1.1 PRELIMINARY

* When using this meter, the user must observe all normal safety rules concerning:

－

Protection against dangers of electronic current.

－

Protection of the meter against misuse.
* Full compliance with safety standards can be guaranteed only if used with test
leads supplied. If necessary, they must be replaced with the same model or same
electronic ratings. Measuring leads must be in good condition.

1.2 DURING USE
* Never exceed the protection limit values indicated in specifications for each range
of measurement.
* When the meter is linked to measurement circuit, do not touch unused terminals.
* When the value scale to be measured is unknown beforehand, set the range
selector at the highest position.
* Before rotating the range selector to change functions, disconnect test leads from
the circuit under test.
* When carrying out measurements on TV or switching power circuits, always
remember that there may be high amplitude voltage pulses at test points which can
damage the meter.
* Never perform resistance measurements on live circuits.
* Always be careful when working with voltage above 60V dc or 30V ac rms. Keep
fingers behind the probe barriers while measuring.

WARNING

* Before attempting to insert transistors for testing, always be sure that test leads have

been disconnected from any measurement circuits.
* Components should not be connected to the hFE and capacitor socket and the
thermocouple has been removed when making voltage measurements with test leads.

1.4 MAINTENANCE
* Before opening the meter, always disconnect test leads from all sources of electric
current.
* For continue protection against fire, replace fuse only with the specified and current
rating:
F1: F2A / 250V F2: F 10A/250V
*If any faults or abnormalities are observed, the meter can not be used any more and
it has to be checked out.
*Never use the meter unless the back cover is in place and fastened fully.
*To clean the meter, use a damp cloth and mild detergent only, do not use abrasives
or solvents on it.
