7 Performance Tests and Calibration
Calibration Overview
N O T E
This manual contains procedures to verify the instrument’s performance and adjustment (calibration).
The performance test procedures allow you to verify that the handheld digital multimeter is operating within its published specifications. The adjustment procedures ensure that the multimeter remains within its specifications until the next calibration.
Make sure you have read the “Test Considerations” on page 118 before calibrating the instrument.
Closed-case electronic calibration
This instrument features closed- case electronic calibration. No internal mechanical adjustments are required. The instrument calculates correction factors based upon the input reference value you set. The new correction factors are stored in the nonvolatile memory until the next calibration adjustment is performed. The nonvolatile EEPROM calibration memory is retained even when the power is switched off.
Agilent Technologies calibration services
When your instrument is due for calibration, contact your local Agilent Service Center to enquire about recalibration services.
