other end,
→
Perform a long press on the TEST key; the measurement starts when the key is released and lasts
approximately 30 seconds,
→
Perform another long press on the TEST key to return to voltage measurement.
Possible error messages:
Display - Indication Remark - Possible cause
The instrument detects a voltage > 2V between terminals L,N and/or
PE : the compensation is not taken into account. A long press on the
TEST key causes a return to voltage measurement.
The measurement is > 5

: the compensation is not taken into
account. A long press on the TEST key causes a return to voltage
measurement.
3.4 RECORDING MEASUREMENT RESULTS (MEM)
IMPORTANT - Each measurement stored in the instrument is identified by 2 indices: an OBJ no.
and a TEST no.; a given object (OBJ) generally contains several TEST nos.
For example: an OBJ no. can be used to locate an installation, and the TEST nos. identify the various
measurements made on this installation.
At any time, the user can store the result of a measurement and all of the parameters associated with
the measurement: date, time, type of measurement, measurement parameters, etc.
