4.3.1 DC and AC Voltages up to 500 V
➭
Set range switch to the posi-
tion 500 V
or 500 V
.
➭
Plug test leads into the instru-
ment; (black) test lead to
socket „
⊥
“ and (red) lead to
socket „+ V, “.
For safety reasons, the test
leads with shock-protected
connection plugs should be
used.
➭
Apply the voltage measured to
the test leads. For DC voltage,
socket „
⊥
“ must be connected
to the negative pole of the
measured voltage and socket
„+ V,A
“ to its positive pole.
➭
If the measured voltage is less than 150 V, set range switch,
in the case of DC voltage, to the lower DC voltage ranges
and, in the case of AC voltage, to the lower AC voltage
ranges, proceeding until optimum deflection is obtained.
➭
Read off the measured value: for DC voltage, on scales
0 ... 5 or 0 ... 15 V, A
, for AC voltage, on scales 0 ... 5 or
0 ... 15 V, A
