Example of timer execution
Let us assume that the you wish to switch on the instrument on 14th of
September at 3 am, measure noise for 1 minute and save the results in a file
named
L1 .
To do this set the Timer parameters, set the measurement parameters ( path:
<Menu> / Measurement / General Settings ), name the file ( path: <Menu> /
Measurement / Logger / Logger Setup ) as on the attached screens and finally
– switch off the instrument.
The instrument will be switched on 14th of September at 2:59 and will be
warmed up for the period of 60 seconds decrementing the counter visible on
the display by one after each second.
After warming up and the pre-set Start Delay time, the measurements will be
performed by a period of one minute. Then, results will be saved in the
previously named file and finally
– the instrument will turn itself off.
