Keysight U1401B User’s and Service Guide
Calibration Overview
This manual contains procedures for verifying the instrument performance, as well
as procedures for making adjustments where necessary.
The performance test procedure verifies that the Handheld Multi-Function
Calibrator/Meter is operating within its published specifications. The adjustment
procedure ensures that the multimeter remains within its specifications until the
next calibration.
Closed-case electronic calibration
This instrument features closed-case electronic calibration. In other words, no
internal electro-mechanical adjustment is required. This instrument calculates
correction factors based on the input reference signals you feed into it during
the calibration process. The new correction factors are stored in non-volatile
EEPROM memory until the next calibration (adjustment) is performed. The
contents of the non-volatile EEPROM memory will not change even when the
power is switched off.
Keysight Technologies’ calibration services
When your instrument is due for calibration, contact your local Keysight Service
Center to inquire about recalibration services.
Calibration interval
A one-year calibration interval is adequate for most applications. Accuracy
specifications are warranted only if calibration is performed at regular intervals.
Accuracy specifications are not warranted beyond the one-year calibration
interval. Keysight does not recommend extending calibration intervals beyond
2 years for any application.
CAUTION
This instrument should only be calibrated by qualified personnel with the
appropriate equipment. For detailed information about the calibration
procedures, please contact your nearest Keysight Technologies
representative or authorized distributor.
