Frequency Accuracy Calibration
This calibration procedure applies to all models (34460A/61A/65A/70A).
Review
Test Considerations
Configuration: Frequency, 10 V range
The frequency accuracy of the Fluke 5720A is insufficient to calibrate the DMM. Its frequency output needs to
be calibrated against a more accurate reference. The Keysight 33500B Series Function/Arbitrary Waveform
Generator is recommended for this calibration procedure.
1. Configure the instrument for frequency measurements at 10 V and 10 kHz, with 1 second gate time.
2. Apply a 10kHz sine wave, amplitude 20Vpp.
3. Enter the actual applied input frequency (see
ceeded message indicates success; if the display shows Calibration Step Failed, check the input
value, range, function, and entered calibration value and repeat the calibration step.
4. Store the new calibration constants (see
