c) Current Measuring “A“
Do not exceed the maximum permitted input values. Do not touch any circuits or
parts of circuits if there could be voltages higher than 25 V ACrms or 35 V DC pre-
sent within them. Danger to life!
The voltage in the measuring circuit may not exceed 1,000 V in CAT III.
Measuring >5 A may only be performed for max. 10 seconds and at 10 minute inter-
vals.

Always start current measurements at the highest measurement range and switch down to
lower ranges if necessary. Before changing the measurement range, always shut off the circuit.
All current measuring ranges are secured with fuses and thus protected against overload.

Proceed as follows to measure DC voltages (A
):
-
Turn the DMM on and select measuring range “A
”.

The table shows the different measuring functions and
possible measuring ranges. Select your measuring range
and the respective measuring jacks.

When a minus “-” appears in front of the measured value when measuring DC, the measured
voltage is negative (or the measuring lines have been mixed up).

After measuring, remove the measuring lines from the measured object and turn the DMM off.
Proceed as described above to measure alternating currents (A
).

Turn the DMM on and select measuring range “A
”. Press “SELECT” (3) to switch to the AC mea-
suring range at the VC850. “AC” appears in the display. Pressing this button again, takes you back

Do not measure any currents above 10 A in the 10A range and no currents above
600 mA in the mA/µA range, otherwise the fuses trigger.
