Setting trigger value

This function defines the trigger threshold to store a value.The trigger value is
defined as a percentage of the full scale deflection.
Example: A trigger value of 2 % at full scale deflection of 500 ppm will only store
values if they deviate by 10 ppm (relative to the previously stored value).
1. Select Settings > Data logger > Datalogr. on/off Trigger value and confirm.
2. Set the trigger value and confirm.

Relays

The instrument ships with all relays (A1, A2, FLT) configured by default to normally
energized. This provides a "fail-safe" operation.
62
The maximum value (if monitoring falling
concentrations, the minimum value) of
the measured concentrations within the
selected sampling time is stored.
The average value of all the measured
concentrations within the selected sam-
pling time is stored
Measurements are stored if they exceed
a threshold beyond the trigger value (rel-
ative to the last stored value).
Measurements within the sampling time
are stored.
Once the capacity of the data logger is
reached, the old data are overwritten by
new values.
Once the capacity of the data logger is
reached, no more data can be stored.
The instrument issues a warning.
