SVAN 973 User Manual 44
In the positions: Monday , Tuesday
, …,
Sunday ; you can select days in a week
when measurements should start.
The timer can be programmed for Max days ahead (
up
to 100) or without
limitation ( Inf ) and during these days, the instrument refers to the time of the R eal
T ime C lock ( RTC ).
Note: Make sure to check that the real-time clock settings are correct before using the timer.
Note: Make sure that there is sufficient internal batteries power available for the instrument to
carry out the required measurements when it wakes up.
4.9.1 Example of timer execution
Let us assume that you wish to switch on the measurement on Monday at 22:00,
to measure noise level for 10 minutes and save results in the files with names R1,
R2, R3 etc.
To do this configure the Timer function as on the attached screen and to set the
measurement parameters ( path: <Menu> / Measurement / General Settings ) and
the file name ( path: <Menu> / Measurement / Logging / Logger Setup ).
The instrument will start to warm up during 30 seconds before the measurement
start time 22:00 on the nearest Monday.
The measurement will be performed by a period of ten minutes. Then, the results
will be saved in the file with the name R1 automatically and the instrument will be
waiting for the next Monday to start measurement at 22.00. Next file will be
automatically named R2 and so on.
Such cycle will be repeated so many times as was defined by the Max days
parameter. If more than one day in a week is selected, every performed
measurement will increase the day-counter. The measurement cycle stops when
the day-counter number is equal to
Max days . If Inf value is selected the
measurement cycles can be stopped only by the user (of course, if the power is
assured).
