Datalogger

The datalogger has a
3000 measurements. At a sampling interval of 1 minute,
this would allow monitoring for approx. 50 hours. The monitoring
time can be significantly increased if the Trigger function
is enabled.
The results in the datalogger can only be evaluated with the
PolySoft 8000 PC software. An evaluation of the datalogger
contents over the last 15 minutes is available in the menu
under Information > Datalogger > Graph (see chapter 7.3.2
on page 18).
8.5.1 Switching the datalogger on or off

On Concentrations will only be stored if they
exceed (relative to the last stored value)
a threshold set under Trigger Value.
Off The measurements made within the set
sampling time are always stored.
Setting the trigger threshold
The trigger threshold is specified as a percentage of the
maximum range.
Example: A trigger threshold of 2 % is entered for a maximum
range of 500 ppm. Consequently the datalogger will only store
measurements if they deviate (relative to the last stored value)
by 10 ppm.
1. Select Settings > Datalogger > Datalogr. on/off >
Trigger value and confirm.
2. Set the trigger value and confirm.
