AC current gain adjustment procedureReview the Test considerations and Gain adjustment considerations before proceeding with this procedure.AC voltage gain adjustment for 100 mV range calibration have to be completed prior to performing the AC currentgain adjustments procedure.Calibration mode: AC Current1. Press Measurement to select ACI. The initial calibration range is 10 mA.2. The measurement displays the uncalibrated value and the Calibration Point displays the reference value.3. Apply the input signal as indicated in the table below.4. Press Calibration Run to start the adjustment. The calibration status is indicated as follows:– PASS: Successful completion of each adjustment value.– FAIL: An adjustment failure. Check the input value, range, function, and entered adjustment value to correctthe problem and repeat the adjustment step.5. Repeat steps 3 through 4 for each gain adjustment point indicated in the table below.6. When the calibration has been completed for the selected range, you will be prompted "Calibration for thisrange is completed".7. Press Calibration Store Value to store the calibration constants for an individual range.8. Increase the range (Press Range to select the next range value) and continue the calibration by repeating steps3 through 7.9. Verify the AC current gain adjustments using AC current verification test.Input Instrument settingsAC Current, Sine (Arms) Frequency Function Range1 mA, 7 mA, 10 mA 1 kHz AC current 10 mA10 mA, 70 mA, 100 mA 1 kHz 100 mA0.1 A, 0.7 A, 1 A 1 kHz 1 A0.3 A, 2.1 A, 3 A[a] 1 kHz 3 A[a] Set calibrator to output 2.99999 A to retain connection to Fluke 5522A's AUX HI+LO output terminals.38 Keysight EDU34450A Service Guide
