Special reference condition

-3-phase and sinusoidal network with 50 Hz or 60 Hz stable frequency

Characteristics

-  Frequency range: 47 Hz to 53 Hz or 57 Hz to 63 Hz.

-  Acceptable voltage range: 50 V to 600 V

-  Acceptable phase imbalance rate: ±10°

-  Acceptable amplitude imbalance rate: 20%

-  Acceptable voltage harmonic distortion: 10%

Running of phase rotation direction detection sequence

Note 1:

In the following table, display of the symbol                refers systematically to the beginning of sequence

Note 2:

The sequence of the following table is described using:

- L1 on terminal “COM”

- L2 then L3 on terminal “+” The same result is obtained if:

- L2 on terminal “COM” , L3 then L1 on terminal “+” or:

- L3 on terminal “COM” , L1 then L2 on terminal “+”

Note 3:

The measurement principle is based on a certain frequency stability and practically sinusoidal signals (THD < 10%).

This excludes in particular measurement on power generators whose spin stabilisation system is too weak to ensure

adequate frequency stability.

3.12 Secondary Functions

3.12.1 Display lock

A short pressing on the 

HOLD 

key freezes the display.

A second pressing unlocks the display.

3.12.2 Preselection of MIN/MAX mode

A short pressing on the 

HOLD

 key then on the 

MIN/MA

X key preselects the MIN/MAX mode. A second pressing

on the HOLD key makes the MIN/MAX mode effective.

This function is used to select the MIN/MAX mode upon request to prevent, for example, the unwanted or mistaken

integration of MIN/MAX values.

measurement, the following messages

may be displayed (after 10 s max):

-- determination of period for

    measurement in progress

-- ontact on L3 a was performed too late

   (more than 10 s after display rEF OK)

-- voltage incorrect

-- equency incorrect

-- dtermination of phase direction

    impossible

-- direct direction of phase rotation

-- reverse direction of phase rotation
