Measurement start and stop
The Start (hh:mm) and Stop (hh:mm) positions
determines times of measurement’s `start and stop. `
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 Real
Time Clock (RTC). The measurement series stops when the day-counter number
will be equal to Max days. If Inf value is selected the measurement series can
be stopped only manually (if the power is assured). If more than one day in a
week is selected, every performed measurement will increase the day-counter.
After programming the Timer, you can turn off the instrument and it will turn itself
on before each measurement. However, there is a minimum time between turning
off the instrument and the set time in the Timer, which is 10 minutes. If you try to
turn off the instrument during this time, a question will appear whether you really
want to turn off the instrument, because it will also turn off the set Timer.
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 14:54,
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 14:54 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 14:54. Next file will be
automatically named R2 and so on. Such measurement will be repeated so many
times as was defined by the Max days parameter.
