C) Measuring Current 'A - VOLTCRAFT WBM-460 Bedienungsanleitung

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
- 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.

- 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.
