Checking the battery voltage
If the pointer is within the zone marked with the battery symbol „ “
after the instrument has been turned on then the battery voltage is suf-
ficient that is, it is assured that the error limits according to the data
given in chapter 5 „Technical Data“ are maintained.
4.3 Voltage Measurement
Attention!
!
Regardless of the magnitude of the voltage being measured,
for safety reasons, the sum of the voltage being measured
and the voltage to earth must not exceed 600 V CAT II or
300 V CAT III when the multimeter is connected directly!
If possible, take the connection socket, marked „“, immediately to
earth or to the point having the lowest potential to earth when making
any voltage measurements.
4.3.1 DC and AC Voltages up to 600 V (Direct Connection)
Ð Set the range switch to posi-
tion 600 V or 600 V~.
Ð Connect the measurement
cables as shown.
With DC voltage note the po-
larity! The „“ jack must be
grounded. For safety rea-
sons, leads with connection
plugs that are protected against accidental contact (KS17-2) should
be used.
Ð Set switch to position „ON“.
Ð Work down to lower voltage ranges until optimum indication is ob-
tained.
Ð Read the measuring voltage on the VA scale.
Note: Overload protection up to 600 V is provided by a PTC thermis-
tor; cooling time of the thermistor until the start of next measurement:
grant at least 2 minutes.
