Notes for list of calibration items:
1 Press or to select the calibration item (if not performing the complete set of calibration). After successfully
calibrating an item, the multimeter will automatically proceed to the next item.
2 Both AC V positions must be calibrated individually.
3 The minimum AC current output of the Fluke 5520A calibrator is 29.0 μA, therefore, an output of at least 30.0 μA must be
set for the calibrator.
4 Be sure to recalibrate the “Short” using the dual banana plug with copper wire after performing calibration for resistance.
5 Ensure that the multimeter is turned on and stabilized for at least 60 minutes, with the K-type thermocouple connected
between the multimeter and the calibrator out terminal.
