Compare the reading on the Meter display with the Display Reading in Table 3. 5. If the display reading falls outside of the range shown in Table 3, the Meter requires calibration adjustment or repair.

    -1.0 to 1.0 400 °C 395.0 to 405.0 [1] If using a Fluke 9100 calibrator, the Calibrator Frequency mode must be used to obtain accurate frequency. Calibration Adjustment The Meter features closed-case calibration adjustment using known reference sources. The Meter measures the applied reference source, calculates correction factors, and stores the correction factors in nonvolatile memory.

Calibration Adjustment Password To start the Calibration Adjustment Procedure, the correct 4-digit password must be entered. The default password is “1234”. The password can be changed or reset to the default as described in following paragraphs. Changing the Password Use the following steps to change the Meter’s password: 1.
