PERMANENT OPERATION

Pressing the RANGE button, when switching On (selection of A AC or V AC), cancels Auto
Off; the clamp is in permanent operating mode. The symbol P is displayed. To cancel
permanent operation reset the switch to OFF.

CHECKING THE BATTERY

By pressing one of the buttons, when switching On, all the symbols are displayed and the
battery symbol and one of the bars of the bargraph flash.
This bar indicates the number of hours still remaining.
The scale is therefore 60 hours and one bar represents 2 hours.
If the arrow on the right flashes: service life greater than 60h.
When the 0 bar flashes, the specifications of the clamp are not within the operating range.
The average service life with a 9.5V alkaline battery is 50 hours.
During operation of the clamp, the battery test is performed every 4 seconds ; if the battery
voltage drops below 6V, the battery symbol is displayed ; change it.

NB : - The HOLD button has priority and is On in all configurations, but it does not inhibit the
operation of the analogue output.
- It has no effect on the analogue bargraph which continues to give the current value
A AC or V AC.
- The RANGE button, on HOLD mode, remains On to allow you to change the range of
the analogue bargraph.
- On RECORD mode, the HOLD button pauses recording: see HOLD-RECORD-PAUSE
procedure. When HOLD mode is exited, the recorded values are not reinitialised and the
recording continues.
- On HOLD mode, it is possible to select the RECORD mode, without starting it. The recording

a particular moment.
RANGE : range selection

- Press the RANGE button to select manual mode: RANGE is displayed.
- By successive presses, select the 1st or the 2nd range of measurement on the digital
display and the analogue bargraph.
- A long press (2 seconds approx.) resets the clamp to auto mode.
NB : There is no manual range selection for digital display for the following functions:
- frequency Hz
- total harmonic distortion THD%
- distortion factor DF%
- crest factor DF%
On the other hand, the RANGE button allows you to select the range of the analogue
bargraph whatever the measurement mode, including with the HOLD mode.
SMOOTH/PEAK : Smooth or Peak values
This button allows you, by successive presses, to select SMOOTH mode, PEAK mode and
