10.3.
DURING A RECORDING
If during a recording the external power supply is de-energised, the instrument will
continue the recording using the internal battery power until the batteries are exhausted
(the data stored up to the point the instrument shuts down won't get lost). For this we
recommend you ALWAYS insert a new set of batteries before a long recording.
The instrument uses sophisticated algorithms to prolong the battery life. Particularly if the
instrument is recording or is measuring energy (and the external power supply is not
connected), after about 5 minutes from the last key pressure or switch rotation the
instrument starts a special procedure to save the batteries ("ECONOMY MODE"): the
instrument keeps recording but the display is turned off.
During a recording the following are disabled:
AUTOPOWER OFF function
ON/OFF key
HOLD key
SAVE key
