DESCRIPTION:
This screen is used to view and set the
temperature calibration values.
This screen should be used anytime a temperature sensor
is found to be out of calibration. The recommended prac-
tice for adjusting the calibration reading is to
fi
rst deter-
mine which sensor(s) need to be calibrated. Once this is
determined, 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 Digital Volt Meter,
or temperature probe, etc. Determine the difference be-
tween what the Current Value for the sensor is, and what
the reading of the separate device shows. As an example,
assume that the Suction Temperature on this screen reads
120° F, but a separate device shows a reading of 123° F.
Select either the Current Value box and enter 123 there,
or enter the difference between the Current Value and the
actual reading (3) into the Offset box. The new reading
will now be 123, and should match your separate reading.
The following
fi
elds are provided:
TEMPERATURE
Sensors
- The following sensor values are dis-
played along with the unit of measure at the left
side of the screen:
• Suction
• Discharge
• Oil
• Separator
• Process
Leaving
• Process
Entering
• Outside
Ambient
• Vyper
Coolant
• Panel
[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.
