a. TPC “Calibration” Module Procedure
This procedure assumes the front panel is removed.
1. Ensure power is OFF.
2. Remove the sensor leads from the Temperature
Module.
 3. Removethe0-5VDCleadsfromtheTemperature
Module.
4. Press TP Calibration Module (TPC) rmly into sensor
  inputconnectorsasshowningureIII.C.5.
 5. AttachtheDVMtothe0-5VDCoutputontheTPC
  module.SeegureIII.C.5.
6. Turn power ON.TheDVMshouldindicate0.0 volts.
7. If not, adjust the calibration control marked “ZERO”
  (seegureIII.C.1forlocation)untiltheDVMindicates
0.0voltsasshowningureIII.C.5.
 8. PressswitchontheTPC.SeegureIII.C.6.
 9. TheDVMshouldindicate5.0volts.SeegureIII.C.6.
10. If not, while pressing the TPC Module switch, adjust
the calibration control marked “FS”(seegureIII.C.1for
  location)untiltheDVMindicates5.0 volts as shown in
  gureIII.C.6.
11. Press the front panel TEMPERATURE select switch
and the TPC Module switch, the display should
indicate 199.9asshowningureIII.C.7.
12. If not adjust the calibration control marked “DIS” (see
  gureIII.C.1forlocation)untilthereadingis199.9 as
  showningureIII.C.7.
13. Calibration is complete.
14. Turn power OFF.
15. Remove TPC Module by pressing on each Phoenix
connector release lever*.
16. Reconnect sensor leads as labeled.
 17. Reconnect0-5VDCoutputleadsaslabeled.
18. Continue or reinstall the front panel and tightly secure
four (4) retaining screws, see REASSEMBLY below.
*CAUTION:Thesensorinputand0-10VDCoutputconnectors
require only a small screwdriver or a pen to push on the release
levers. The release levers may be broken or damaged if not
pushed straight toward the CB. DO NOT push the release levers
sideways.
b. Precision Resistor Calibration Procedure
This procedure assumes the front panel is removed.
1. Ensure power is OFF.
2. Remove the sensor leads from the Temperature Module.
 3. InstallZEROresistor(1000.0Ω)acrosssensorterminals
  BLandOR.SeegureIII.C.8.
4. Install JUMPER between BR & BL as shown in
  guresIII.C.8&III.C.9.
 5. AttachtheDVMtothe0-5VDCoutput.See
  guresIII.C.8&III.C.9.
6. Turn power ON.TheDVMshouldindicate0.0 volts.
7. If not, adjust the calibration control marked “ZERO”
  (seegureIII.C.1forlocation).
 8. InstallSPANresistor(1758.56Ω)acrosssensor
  terminalsBLandOR.SeegureIII.C.9.
 9. TheDVMshouldindicate5.0 volts.
10. If not, adjust the calibration control marked “FS” (see
  gureIII.C.1forlocation)untiltheDVMindicates5.0
  voltsasshowningureIII.C.9.
11. Press the front panel TEMPERATURE select switch,
the display should indicate 199.9 as shown in
  gureIII.C.10.
12. If not adjust the calibration control marked “DIS” (see
  gureIII.C.1forlocation)untilthereadingis199.9.
13. Calibration is complete.
14. Turn power OFF.
 15. RemoveDVMfrom0-5VDC.
16. Remove resistor and jumper by pressing on each
Phoenix connector release lever*.
17. Reconnect sensor leads as labeled.
 18. Reconnect0-5VDCoutputleadsaslabeled.
