2.5

BUTTON

This button is used to display the frequency measurements of a signal.

NOTE:

This button is not functional in the DC mode.

2.5.1

Normal Mode

Successive

presses on

Function

short

Displays:

- The frequency of the signal measured

- The present voltage (V) or current (A)

measurement

Displays:

- The apparent power (VA)

- The reactive power (var)

- The power factor (PF)

- The frequency of the signal

- The active power (W)

long

- Enters or exits from the level of harmonics

(THD) calculation and display mode

then short

- Selects THDf, THDr or the frequency of the

fundamental

2.5.2

The Hz Fu Activation of the HOLD Mode

Successive

presses on

Function

Holds the last frequency reading

Successively displays the last held
frequency, then the voltage or the current

Displays the stored values of THD

, then of

THD

, then of the frequency of the

fundamental

NOTE:

Pressing the

button again

returns to realtime measurement updates.
