DC or AC+DC Measurement
Set the switch to
and select DC if the display does not indicate "0"; the DC
zero must be corrected first.
Step 1: Correction of DC Zero
Important:
The clamp must not be closed on the conductor during the DC zero
correction. Hold the clamp in the same position during the whole procedure so
that the correction value will be exact.
Press the
button until the device emits a double beep and displays a value
near "0". The correction value is stored until the clamp is powered down.
NOTE:
The correction is effected only if the value displayed is < ±20A, otherwise
the value displayed blinks and is not stored. The clamp must be recalibrated (see
§ 5.3)
