– Positive Zero Temperature Compensation
This option is used to apply temperature compensation to the sensor, a zero value
results in no applied compensation.
The value can be either positive or negative, depending upon the type of sensor fitted.
The value is best selected by first calibrating the sensor at 20
C then raising the FGD3
to 50
C. When the temperature is stable, usually after 2 hours, the value is set such
that an accurate zero reading is displayed.
Note:
changing this value from the factory setting may make the readings
inaccurate
– consult Status Scientific Controls Ltd before making any
changes.
