8.5 Datalogger settings (only with data dongle)
The datalogger has a storage capacity of approx.
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 17).
8.5.1 Switching the datalogger on or off
1. Select Settings > Datalogger > Datalogr. on/off
and confirm.
2. Select On or Off and confirm.
8.5.2 Setting up the datalogger
Setting the sampling interval
1. Select Settings > Datalogger > Datalogr. on/off >
Sample time and confirm.
2. Select the sample time and confirm.
Setting peak/average
1. Select Settings > Datalogger > Set datalogger > Peak/

Switching the trigger on or off
1. Select Settings > Datalogger > Set datalogger > Trigger

Setting the trigger threshold
The trigger threshold is specified as a percentage of the full
scale reading.
Example: A trigger threshold of 2 % is entered for a full scale
reading 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.
Setting the storage mode
1. Select Settings > Datalogger > Set Datalogger > Stack/

Peak value The measured maximum (for O
2
, the minimum
value) value of the concentration within the
selected sampling interval is stored.
Average The average value of all the concentrations
measured within the selected sampling time
is stored.
i i
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.
Overwrite When the capacity of the datalogger is
used up, the older data will be overwritten.
Hold When the capacity of the datalogger is
used up, no more data can be stored.
An appropriate warning is issued.
