c) Current Measuring “A“
The voltage in the measuring circuit may not exceed 600 V.
Do not measure any currents above 10 A in the 10A range and no currents above 400
mA in the µA/mA range, otherwise the fuses trigger.
Measuring >5 A may only be performed for max. 30 seconds and at 15 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 cur-
rent measuring ranges are secured with fuses and thus protected against overload.
Proceed as follows to measure “A-DC” di-
rect current:
• Turn the DMM on and select measuring
function “A”.
• The table shows the different measuring
functions and possible measuring ranges.
Select your measuring range and the re-
spective measuring jacks. The display indi-
cates “DC”.

• Insert the red measuring line into the µA/mA or 10A measuring jack. Plug the black measuring
line into the COM socket.
• Now connect the two measuring prods in series to the object to be measured (battery, switch
etc.). The polarity of the respective measured value is indicated on the display together with
the measured value.
When a minus “-” appears in front of the measured value when measuring DC, the
measured voltage is negative (or the measuring lines have been swapped).
After measuring, remove the measuring lines from the measured object and turn the DMM off.
