7.2.5 Set interval mode
When operating the AlphaGUARD in the interval mode, the measurement takes
place just in defined time period for a defined sample time, e.g. every 60 minutes
for 30 minutes. With this mode an extended battery life time can be achieved for
flow operation.
The interval mode can be activated by choosing “ON” pressing the Scroll up or
Scroll down button and pushing the Enter button for 2 sec for acknowledgement.
The interval mode can be configured by the following parameters:
Pre-sample
time:
Activated pump to flush the measurement chamber before
sampling is started
During the Pre-Sample time no measurement is performed
Sample time:
Activated pump and running measurement
Time period:
The time period includes the complete time interval (from the
start of the sampling time to the start of the next sampling time)
Start time:
Start time of the first sample time
Set Interval mode 10min

Pre-sample time:
Measuring time: 30 min
Interval time: 120 min
Interval start: 16:00

- The interval time has to be longer than the pre-sample time + the measuring
time.
-
Within the sample time the measurement values are stored according to
the selected operation mode. In the meantime, no measurement values
are stored and the read-out data series shows gaps for these periods.
