Safety Notes
This appliance corresponds to the directive for electromagnetic com-
patibility 89/336/EEC and the low voltage directive 73/23/EEC.
With this instrument dangerously high voltages can be measured.
When measuring voltages from 42 V on be especially careful.
Always take care that the test leads are in perfect condition.
Damaged test leads must be replaced.
Always watch the following items regarding the operation:
●
The unit is only suitable for indoor use.
●
Protect the unit from humidity and heat (permissible ambient
temperature range 0 – 40 °C).
●
If the unit is used for purposes other than originally intended, if it
is overloaded or operated, connected or repaired in the wrong
way, there is no liability for possible damage.
●
Only use a dry, soft cloth for cleaning, by no means chemicals or
water.
●
If the unit is to be put out of operation definitively, bring it to a
local recycling plant for disposal.

Applications
With this multimeter DC and AC voltages, DC currents, resistances
as well as decibel can be measured. Furthermore 1.5 V (AA size)
and 9 V batteries can be tested. For the continuity check a buzzer
is provided. With model MT-300 transistors can additionally be
tested (display PNP or NPN type by LEDs).
