4 Measurements
Prior to selecting another measuring function, remove the
test prods from the test object to prevent damage to the
meter.
4.1 Voltage measurement
4.1.1 DC voltage
Set the rotary switch to the highest or – if already known –
to the suitable DC V position. Overflow, i. e. if the range is
chosen too low, is displayed with “1”or “-1”. Reversed po-
larity in relation to the measuring jacks is displayed as a
minus sign. Mixing up of the measuring cables with each
other is not dangerous.
WARNING
Take into account unexpected voltages at
test objects. Capacitors, for example, may
be dangerously charged even if the voltage
source has been switched off.
●
With this meter, no measurements must be carried out
in circuits with corona discharges (high voltage). Dan-
ger to life!
●
The maximum voltage to be measured must not exceed
600 V
¿
/ ~, otherwise you may risk your life!
WARNING
Measurements in circuits carrying more than
42 V must only be made by persons able to
recognize a hazard of contact and to take
the required safety precautions. In case of
measurements with a hazard of contact,
avoid working on your own. Ask a second
person to assist.
