CALIBRATION – Ammonia Sensors
DESCRIPTION: This screen is used to calibrate any installed
Ammonia sensors.
NOTE: Each Ammonia sensor that is to be used must be
calibrated before the system is put into operation. Page 1
allows for calibration of Ammonia Sensors 1 through 15,
Page 2 allows calibration of Ammonia Sensors 16 through
30.
The displayed value of each installed ammonia sensor should
be compared against the reading of a calibrated ammonia de-
tector, and any compensation should be made to the sensor
on this screen.
The following Setpoint boxes appear here:
Current Value – This box shows the actual value that the
sensor is detecting.
Offset – This box is used to adjust (compensate) the value
shown in the Current Value box. If the Current Value were
displaying 100, but an ammonia detector were showing
95, the difference of 5 should be entered here.
Range
Low - Set the Low Range value according to the low
range of the sensor itself.
High- Set the High Range value according to the high
range of the sensor itself.
A Sensor Signal type is shown at the end of each row. This is
informational only, and cannot be changed here.
