e) Current measurement in the µA- and mA ranges
You can measure currents of up to 400µA in the µA range and currents of up to 400
mA in the mA range. Both current measuring ranges are provided with fuses and
thus protected against overload.
Proceed as follows to measure dc voltages:
- Connect the black measuring line with the COM socket
(7) and the red measuring line with the V-mA socket (6).
- If you want to measure currents of up to max. 4mA or up
to 400mA , set the range selection switch (5) to position
"µA" or to position "mA", respectively.
- Now connect the two test prods in series with the object
to be measured (battery, switching etc.); the polarity of
the measuring figure concerned will be indicated
together with the current measuring value on the display
(1).
Proceed as follows to measure alternating currents:
- Connect the black measuring line with the COM socket (7) and the red measuring
line with the V-mA socket (6).
- If you want to measure currents of up to max. 4mA or up to 400mA , set the range
selection switch (5) to position "µA" or to position "mA", respectively.
- Press the "MODE" button to change into the AC range; if you press it again you
return to the DC range.
- Now connect the two test prods in series with the object to be measured (genera-
tor, switching etc.); the polarity of the measuring figure concerned will be indicated
together with the current measuring value on the display (1).

Never measure currents higher than 400mA in the mA range.
