Activation / shutdown

Gives access to the various screens by successive presses

Gives access to measurement of the power and PF (power factor) in three-
phase mode with balanced wires , only on the PX 120 (short press)

Used to freeze the display of the values (short press)

Enables filtering of the values measured (short press)

If pressed briefly, enables acquisition of the peak startup current for a motor.
The RMS current value measured is maintained until a higher value is
measured or until you exit from the function.

Housing of the optical communication head

On the back of the instrument, there are:
- The access hatch for replacing the batteries (see § 7.1)
- The stand enabling the instrument to be set up in a tilted position.
- The mains power supply option which is connected in place of the battery hatch.

The liquid crystal display allows the display of
numeric values and the symbol of the
corresponding unit, as well as the symbols of
the different functions.

Digital display
This is made up of 3 display blocks (4
digits, 9,999 counts, 3 decimals and 1 sign
“-”) each with a specific assignment
depending on the function and
measurement mode selected.
If the measurement capacity is exceeded,
it is indicated by 

OL  in the centre of the

corresponding numeric display.

Upper display:

First screen: Displays the value of the voltage in V
Second screen: Displays the value of the reactive power in VAR or kVAR

Middle display:

First screen: Displays the value of the current in A
Second screen: Displays the value of the apparent power in VA or kVA

Lower display:

First screen: Displays the value of the active power in W or kW
Second screen: Displays the value of the power factor
PF: Indicates that the numeric value displayed in the power factor
