10.1 Over-range
Under conditions of measuring range excess, defined at
133,5 dB,
Z peak, an over-range icon appears. Its displaying
differs with the measuring mode selected:
•
L and L-St modes :
- LXY : it comes fleetingly for each passing. It stays visible at least 1s for a better readability.
- LXpk : warning light appears during the first overload of the input stage, it stays visible during all the measurement.
- LXY max and LXY min : the presence of the warning light indicates that displayed minimum and maximum values have been
overloaded.
Deletion of overload warning lights takes place during a controlled reset by keyboard.
•
L-Leq mode
:
- LXY : it comes fleetingly for each passing. It stays visible at least 1s for a better readability.
- LXpk et Leq : warning light appears during the first overload of the input stage, it stays visible until the end of the measurement. (24H
maximum)
•
Leq-St Mode :
- Leq 0,5s : warning light appears for each overload of input stage, it stays visible during the integration time of 0,5s, then switches off
and so on...
- Leq, DI and LXpk : both warning lights appear for each input stage, they stay visible during the integration time (from 1s to 60s), then
switch off and so on...
- Leq, T : warning light appears during the first overload of the input stage, it stays visible until the end of the measurement.

S1+S2
mode
:
- warning light appears at the first overload of input stage for each measurement, it stays visible until the end of the measurement.
•
% of presence of overloads of the input stage :
This information can be required during a mid and long term measurement, when overload indicator is displayed. Its presence does not
provide information about the frequency of occurrence of the overload but the percentage calculation provides a level of alert about
measured and displayed levels by the instrument.
Note :
A LXY minimum value may have been overloaded, for example a level of 110 dBA with a high peak factor, while a LXY
maximum value of 125dBA with a low peak factor can not be overloaded.
10.2 Power
When the instrument is equipped with alkaline batteries or with a battery, a symbol informs the user about the remaining
power. In case of low power, less than one bar on the pictogram, the pictogram starts blinking, the instrument stops the
measurement, saves the results and switches off.
During a mains connection for long term measurements, the pictogram automatically changes to represent a plug.
