"USEr" cable compensation:
→ Set the switch to the 3P, 2P, or Z
→ Connect cables to the 3 terminals (L, N and PE) of the instrument and short-circuit them at the
other end,
→ Perform a long press on the TEST key; the measurement starts when the key is released and lasts
approximately 30 seconds,

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.
Select the type of measuring cables compensation
and display the compensation of each measuring
cable by successive presses on the
key.
