i) DC/AC current measurement

Current measuring operations are possible in two ranges. The first
range is 0 to 4000 µA, the second is 0 to 200 mA. Both current mea-
suring ranges are provided with fuses and thus protected against
overload.
Proceed as follows to measure DC currents:
- If you want to measure currents of up to
4,000 µA, set the rotary switch (1) to set-
ting „µA" and to setting „mA" for cur-
rents of up to 200 mA. The display
shows „DC".
- Now connect the two test prods in
series with the object to be measured
(battery, circuit etc.); the display indi-
cates the polarity of the measured value
together with the currently measured
value.
Proceed as described above to mea-
sure alternating currents.
Press „MODE" (3) to switch to the AC range. Pressing this button
again, takes you back etc.
Never measure currents above 200 mA in the µA/mA
range, since this would cause the fuse to trip.
If the fuse tripped (measured value does not change
etc.), turn the DMM off (OFF) and wait about five min-
utes. The self-resetting fuse cools down and then func-
tions again.
