Datalogger
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 18).

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.

Peak value
The measured maximum value (for O
2
, the
minimum 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.
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.
