Note :
If no threshold value has been programmed, when
(button inoperative) will be emitted by the buzzer and this will not be taken into account.
Sound signal :
The minimum duration of operation of the buzzer on an alarm is 400ms even when this
takes place on a peak value of lesser duration.
When a threshold is crossed, a hysteresis of 1% is applied to its set point, which obliges
the measurement to fall below this lesser value to exit the alarm.
Triggering the alarm :
The digital measurement is below the low threshold, the buzzer switches On and the
low overhead symbol,
The digital measurement is above the high threshold, the buzzer switches On and the
high overload symbol,
The digital measurement is below the low threshold or above the high threshold (with
programmed value of the low threshold below the programmed value of the high thres-
hold), the buzzer switches On and the corresponding overload symbol is displayed.
If, during programming, the value of the low threshold

Notes:
- When the SMOOTH or PEAK function is in service, detection by the alarms is done on the
smooth or peak values.
- On the HOLD function, the comparison of the programmed thresholds continues to be done
on the current measurement.
