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 < ±10A, otherwise
the value displayed blinks and is not stored. The clamp must be recalibrated (see
§ 5.3)
Step 2 : Make a Measurement
1. The switch is set to . Select DC by pressing the (yellow) button
until the desired choice is reached.
2. Clamp the jaws around the conductor to be measured.

3.13 ADAPTER FUNCTION MEASUREMENT
This function makes it possible to connect any adapter or sensor that converts a
measured electrical or physical quantity into a voltage (either DC or AC). A direct,
immediate reading is obtained without applying a conversion factor.
The measurement mode, AC or DC (the default), must be chosen manually using
the yellow button.
The scale factor for the adapter or sensor must be chosen in advance in the
instrument’s set-up (§3.4.5). The table below indicates the various
adapter/sensor sensitivities that allow a direct reading once the scale factor has
been chosen.
