In the case the timer is active (Single or Multiple) and the instrument is switched on the “clock” icon appears
until finishing the programmed measurements.
The Start Hour position determines the time
for the measurement to start. The required
hour and minute can be selected in a special
screen, which is opened with the ◄ / ► key.
To set hours or minutes, select the left or right
field with the ◄ / ► key and then select the
proper value with the ▲ / ▼ key and press
<ENTER> to confirm settings.
The Start Day position determines the date
for the measurement to start. The timer can
be programmed up to one month ahead. The
required date can be selected in a special
screen, which is opened with the ◄ / ► key.
To set the date, select its position with the ◄
/ ► or ▲ / ▼ key and then press <ENTER>.
The Repetition position is displayed when the
Multiple mode is selected. This parameter
can be programmed in the range from 00:00
up to 96:00. The required date can be
selected in a special screen, which is opened
with the ◄ / ► key same way as Start Hour.
Note: The Timer function can be used for multiple measurements (at the programmed day and time
with the selected repetition number). The first start of the instrument must be within one month ahead.
Make sure that the RTC is configured correctly before setting up the Timer.
Note: Make sure that there is sufficient power available for the instrument to carry out the required
measurement when it wakes up and starts measurements.
4.10.1 Example of timer execution
Let us assume that the you wish to switch on the instrument on 3rd of
December at 20:00, measure noise for 1 minute and save the results in a file
named L2831.
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
– turn off the instrument.
The instrument will be switched on 3rd of December at 19:59 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.
