4.5.2. DATE AND HOUR
The Instrument menu lets you set the your instrument’s date and time.
These cannot be changed while recording or when a recording session has been scheduled.
By clicking
, you can choose the date and time display formats.
4.5.3. AUTO OFF
As default, the instrument switches itself off automatically after 3 minutes of operation without the user’s presence being confirmed
by a key-press. By clicking , you can change this value to 3, 10, or 15 minutes.
It is also possible to disable this auto-off function; the instrument then displays the
P
symbol.
4.5.4. PROGRAMMED RECORDING SESSIONS
By clicking , you can program a recording session. Assign a name to the recording session. Then enter a starting date and time
and an ending date and time or a duration. The maximum duration of a recording session depends on the memory available.
Choose a sampling period. The possible values are: 1 s, 2 s, 5 s, 10 s, 20 s, 30 s, 1 min, 2 min, 5 min, 10 min, 15 min, 30 min and
1 hour. The shorter the sampling period, the larger the recorded file.
Before and after the recording session, if the instrument is switched on, the sampling period will be that of the stand-alone mode (1s).
If the instrument is off when recording starts, it switches itself on by itself. Then it displays the measurement, which it refreshes at
each sampling period.
Before starting a recording session, make sure that the battery life is sufficient, or else connect the instrument to an external
power supply to a wall outlet using a micro USB cord.
