3. Write the "Volt" value read on the Temperature Sensor Trace to Parameter 1028 (Ambient
Temperature Sensor Voltage Calibration).
Where <value> is the "Volt" reading from the trace command (usually about 2.9 at 23 C)
4. Write the current ambient temperature, as read on the digital thermometer, to Parameter
1029 (Ambient Temperature Sensor Temperature Calibration):
Where <value> is the temperature (in degrees Celsius) read at the digital thermometer.
Note: If your thermometer only gives readings in degrees Fahrenheit, use the following equation to
convert degrees F to degrees C.
degreesC = (degreesF - 32) * 5 / 9
5. Wait for the next temperature reading trace to be displayed. Verify that the temperature
in the "Curr:" field is within +/- 1 degree C of the thermometer reading. If not, repeat
calibration procedure.
6. Disable the Temperature Trace with FIPS command:
7. Read the Current Ambient Temperature from the parameter database (r 1026). Verify that
it is within +/- 1 degree C of the thermometer reading. If not, repeat calibration
procedure.
The temperature calibration procedure is complete. The calibration will remain valid
unless a “double DIP” reset is performed, or the OCM board is replaced. (A “double
DIP” reset is performed by placing both DIP switches 1 and 2 on SW500 in the ON
position, then resetting the OCM.)
8. Replace the OCM front panel (Four T15 Torx screws) and remote access FIPS cable.
