Performance Tests and Calibration
Calibration Overview
This manual contains procedures for verifying the instrument performance, as well
as procedures for making adjustments where necessary.

instrument.
Closed-case electronic calibration
The U1211A, U1212A, and U1213A clamp meter 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 non-volatile memory until the next
calibration adjustment is performed. The non-volatile EEPROM calibration
memory is retained when the power is off.
Keysight Technologies calibration services
When your instrument is due for calibration, contact your local Keysight Service
Center for a low-cost recalibration.
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. Keysight
does not recommend extending calibration intervals beyond two years for any
application.
