Calibration Overview
Keysight Technologies Calibration Services
When your instrument is due for calibration, contact your local Keysight
Service Center. The U3402A is supported on automated calibration systems at
Keysight service centres only.
Calibration Interval
A one- 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 one- year calibration
interval. Keysight does not recommend extending calibration intervals beyond
two years for any application. When an adjustment is required, contact your
local Keysight Service Center.
NOTE
Make sure you have read “Test Considerations” on page 64 before
calibrating the multimeter.
