4.5 TESTING THE BATTERIES
The nominal range of the batteries is 6 V to 3.5 V.
The average service life is 40 hours on continuous operation, without backlighting, or 2500 measurements of 1 minute.
4.5.1 Automatic test
No display of the battery symbol: the battery voltage is correct.
Display of the battery symbol
- The battery symbol flashes, remaining service life 1 hour approximately. The accuracy of the clamp is still guaranteed.
- The battery symbol is steady. The accuracy is no longer guaranteed. The battery voltage is then approximately 3.3 V
and if the batteries are not changed, the clamp will switch off automatically.
4.5.2 Manual test
Press and hold the THD button for display of :
- the battery voltage
- the remaining service life in hours
4.6 HOLD : Hold the display
- A brief press on this button freezes the digital displays and HOLD is displayed.
- A second short press resets the clamp to normal mode.
In RECORD mode, the HOLD button temporarily stops the recording (See Ch. MAX/MIN: Recording MAX/
MIN). When quitting HOLD mode, the memorised values are not reinitialised and the recording continues.
In HOLD mode, it is possible to select RECORD mode without starting recording. Recording will start when
HOLD mode is exited; this procedure can be useful to start a recording at a particular time.
4.7 SMOOTH : Filtered value
- Press this button once: SMOOTH is displayed.
The digital values are filtered (over 3 seconds), which has the effect of attenuating display instabilities on
fluctuating signals.
- A second press resets the clamp to normal mode.
NB : SMOOTH mode is not accessible on HOLD - RECORD-PAUSE.
On RECORD mode, press the SMOOTH button to reinitialise RECORD mode, i.e. to cancel the previously
recorded values and restart RECORD mode.
