23. Select Type-E thermocouple.
24. Turn off U.U.T.
25. Replace T calibration-cable with E calibration-cable.
26. Turn on U.U.T. Allow 2-3 minutes for thermal stabilization.
27. Apply 32°F (Type E). Adjust P1 for a reading of 32.0°F (exclusive of
noise).
28. Hit OPR key to store E-meter zero-adjustment.
29. Select Type-K thermocouple.
30. Select CALIB mode.
31. Turn off U.U.T.
32. Connect U.U.T. to test-equipment per Figure 3 using the K calibration-
cable.
33. Turn-on U.U.T. and allow 2-3 minutes, for thermal stabilization
34. Set both the U.U.T. and TC-simulator to output 32.0°F (Type K). Adjust
P2 for a null-meter reading of 0±3µV.
35. Set both the U.U.T. and T-simulator to output 2400°F (Type K). Adjust
P41 for a null-meter reading of 0±3µV.
NOTE: Steps 34 and 35 are interactive. Repeat each as neces-
sary to get the desired null readings.
36. Hit OPR key to store K-calib zero adjustment.
37. Select J thermocouple.
38. Turn off U.U.T.
39. Replace K calibration-cable with J calibration-cable.
40. Turn on U.U.T. Allow 2-3 minutes for thermal stabilization.
41. Set both the U.U.T. and TC-simulator to output 32.0°F (Type J). Adjust
P1 for a null-meter reading of 0±3µV.
42. Hit OPR Key to store J-calib zero adjustment.
43. Select Type-T thermocouple.
44. Turn off U.U.T.
45. Replace J calibration-cable with T calibration-cable.
46. Turn on U.U.T. Allow 2-3 minutes for thermal stabilization.
