DISPLAY

Gives access to the various screens by successive presses
T3FE 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)
HOLD Used to freeze the display of the values (short press)
SMOOTH Enables filtering of the values measured (short press)
INRUSH 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.

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
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
