10. RECORDINGS
10.1. START A RECORDING
The recording function is available for
ANALYZER and AUX rotary switch position.
As you can read in the paragraphs 7.2.1 and 8.2, a recording can be started manually or
automatically. Therefore, after setting all the parameters
and leaving the Menu, the
instrument will start to record:
MANUALLY: the recording will start when Instrument time reach the “00” seconds
value after pressing
START/STOP.
AUTOMATICALLY:
If the operator has pressed START/STOP the instrument will
remain in stand-by until the date and time previously set, then the recording will start.
While
if the operator doesn’t press START/STOP the recording will never start.
CAUTION
For recordings we recommend to use the external power supply
adapter (optional code A0050) even the instrument allows the operator to
perform a recording using internal batteries.
If you press Start a recording without the external power supply adapter (optional code
A0050) the instrument will display a warning message “
No ext supply”. Press START key
again to run the recording or press ESC to quit.
If during a recording the external power supply adapter (optional code A0050) is de-
energised, the instrument will continue the recording using the internal battery power until
the batteries are exhausted (the data stored until the definitive turning off 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:
The instrument switches OFF the backlight Automatically after 5 seconds.
If the Battery level is too low the Backlight function will be disabled.
If the instrument is just displaying in real time (and the external power supply is not
connected), after about 5 minutes from the last key pressure or switch rotation the
instrument turns off automatically ("AUTOPOWER OFF" function).
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.
Before starting a recording the operator should first evaluate the state of the equipment,
decide what to record and set the instrument accordingly.
