c) Measuring current ‘A’
Do not exceed the maximum permitted input values under any circumstances. Do not touch any
circuits or circuit components if the circuit has voltages higher than 33 V/AC RMS or 70 V/DC.
Danger of death!
The maximum permitted voltage in the measuring circuit must not exceed 1000 V in CAT III and 600
V in CAT IV.
Measurements greater than 6 A must only be made carried out for a maximum of 10 seconds in 15
minute intervals.
Always start the current measurement with the largest measurement range and switch to a smaller
range if necessary. Before connecting the measuring instrument and before changing the meas-
urement range, always de-energise the circuit. All current measurement ranges are provided with
fuses and thus protected against overload.
Do not measure any currents above 10 A in the 10 A range and no currents above 600 mA in the mA/
µA range, otherwise the fuses trigger.
Proceed as follows to measure direct (A ) currents:
- Switch the DMM on and select the measuring function ‘10 A’, ‘mA’ or ‘µA’.
- The table shows the different modes and potential measurement ranges. Select the measurement range and cor-
responding measurement sockets.

10 A
0 - 10 A
COM + 10 A
mA
0 - 600 mA
COM + µA mA
µA
0 - 6000 µA
COM + µA mA
- Insert the red test lead into the 10 A or µA mA measurement socket. Insert the black test lead into the COM meas-
urement socket.
- Connect the two probe tips (de-energised) in series to the object that you want to measure (e.g. battery or circuit).
The electrical circuit must be disconnected before you connect the probes.
-
Reconnect the circuit. The measured value appears on the display.
- After measuring, disconnect the circuit and remove the test leads from the measured object. Switch the DMM off.
