5 Performance Tests and Calibration
Calibration Overview
Closed-case Electronic Calibration
The multimeter features closed- case electronic calibration. No internal
mechanical adjustments are required. The multimeter calculates correction
factors based upon the input reference value you set. The new correction
factors are stored in non- volatile memory until the next calibration
adjustment is performed. Non- volatile EEPROM calibration memory does
not change when power has been off.
Calibration Interval
A 1- year interval is adequate for most applications. Accuracy
specifications are warranted only if adjustment is made at regular
calibration intervals. Accuracy specifications are not warranted beyond the
1- year calibration interval. Agilent does not recommend extending
calibration intervals beyond 2 years for any application.
Ensure that you have read Test Considerations before calibrating the multimeter.
