ACCESSING:
DESCRIPTION: This screen is used to view and set sensors
that are not included on the other calibration screens.
This screen should be used anytime a misc. sensor is
found to be out of calibration. The recommended practice
for adjusting the calibration reading is to fi rst determine
which sensor(s) need to be calibrated. Once this is de-
termined, you must know the actual reading that should
be showing. This can be accomplished by comparing the
Current Value shown, with the actual value using a sepa-
rate measurement device, such as a DVM or temperature
probe. Determine the difference between what the Cur-
rent Value for the sensor is, and what the reading of the
separate device shows. As an example, assume that the
Remote Cap. Control Setpoint on this screen reads 5 F, but
a separate device shows a reading of 7 F. Select either the
Current Value box and enter 5 there, or enter the differ-
ence between the Current Value and the actual reading (2)
into the Offset box. The new reading will now be 5, and
should match your separate reading.

[Current Value] - This box will initially show the
actual value being read by a sensor. It is also a
setpoint box that allows the user to set the cur-
rent value that is being read by the sensor to a
different value, in the case that the calibration is
inaccurate, this new value will be added to the
actual value to update the offset (see below).
[Offset] - A value entered here will allow the
user to compensate for calibration issues with
a sensor. This value is then added to the Cur-
rent Value, to create a new Current Value (see
above).
Low - This will show the low end range that the
sensor is capable of reading.
High - This will show the high end range that the
sensor is capable of reading.
Sensor Output - This will show the current type
of sensor that is being used.
I/O Board - This will show the current I/O board
that the sensor is assigned to.
I/O Channel - This will show the current I/O
channel that the sensor is assigned to.
