Range overload
. Automatic mode - Above 600.0V RMS, the warning signal is emitted to indicate that
the voltage measured is outside the specified range.
. Manual mode - Above 99.99V on the 1st range the display indicates "OL" and the
warning signal is emitted.
. Automatic and manual modes - Above 999.9V the display indicates "OL" and the
warning signal is emitted.

NB : - Range selection is always automatic.
- Pressing the RANGE button sets the triggering threshold.
- Below 0.5Hz or if the level of detection is insufficient, the display indicates 0.0Hz.
Triggering threshold
- Automatic : - on voltage from 1V
- on current from 1A
- Manual (RANGE): 10% approx of the voltage or current range selected.
