Attention!
Do. not measure any currents in circuits in which
voltages greater than 250 VDC or
can oc-
cur, to avoid damaging the measuring device and
endangering life as a result. Never measure cur-
rents over 20 A. Measure only in circuits themselves
fused at 16 A and in which no power greater than
4000 VA can occur.
Measurements of currents at 20 A may be for 30 s
duration max. and be carried out only at intervals of
minutes (shunt cooling phase).
D AC current measurement
To measure AC currents, proceed as follows:
1. Connect the black test lead to the COM socket and the red test
lead to the
socket if currents up to max. 400
are to be
measured, or to the
socket if currents between 400
and
max. are to be measured.
2. Position the rotary switch to current measurement
or
-400
or -20 A).
3. Connect the. test leads in series with the object to be measured
(see following illustration).
