Appendix H: Calibration
AI Calibration and CJC Calibration
For AI and CJC Factory and User Calibration see
Sensor Compensation
Sensor Compensation may be required to improve accuracy on a sub range. This is an ad-
justment to the value of the signal input on each channel, based on the Engineering units.
To set this up in the recorder see Sensor Comp in the menu for
Single Point
Set the
Comp Type
to
Single Point
to adjust the signal input reading by an offset amount
determined by the user. Enter the
Offset
adjustment required and this is added or subtract-
ed for all future readings.
Dual Point
Select
Dual Point
to change two points on the signal input reading. The Dual Point adjust-
ment works in the same way but at two different points on the signal input. It is recommend-
ed that the two points should be more than 50%, of the engineering units, away from each
other.
Low Eng
and
High Eng
are the two points where the adjustment offset is made. The user
can enter their own adjustment points on the signal input and enter the
Offset
for both
points.
