10.2. 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 store
d 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
