Manual
If both socket positions are free, the indicat ion SENS appears in the upper line, and
the first sensor can be connected to the left hand socket position.
There are now 10 seconds available (Countdown on the display) to connect an
optional second sensor to the right hand socket position.
Necessary calibration intervals are dependent on the environmental conditions and
the requirements of the permissible tolerance deviations.
A single point calibration of the external sensors can be carried out using a
comparison standard. The captured Offset values can be entered in the SmartGraph
software under: Measuring Instrument / Manage Measuring Instrument / Sensor
Electronics.
Two point calibrations can only be carried out in the factory.
Instructions for using additional extensions for the probes:
The probes are adjusted for the standard cable with a length of 2m.
By using extension cables for the probes the accuracy of the measured relative
humidity degrades.
Using an additional extension cable with a length of 2m or 4m: no change of the
humidity offset is necessary.
Using an additional extension cable with a length of 6m: set an offset value of –0.8%
in the software SmartGraph.
Using an additional extension cable with a length of 8m or 10m: set an offset value
of –1.8% in the software SmartGraph.
Go into software SmartGraph and perform following step:
- instrument -> configuration of instrument
select the instrument
-
sensors -> settings (relative humidity)
-
enter the offset as described above
