[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.
The following sections present the features and Meter pushbutton functions available during the Calibration
Adjustment Procedure. Should the Meter fail any of the performance tests, perform the Calibration Adjustment
Procedure.
Use the following steps to view the Meter's calibration counter.
1. While pressing K, turn the rotary switch from OFF to Ω function. The Meter should display
"CAL".
2. Press g once to view the calibration counter. For example, "n001"
