1 Calibration Procedures
18 Keysight U3606B Service Guide
Calibration Overview
This manual contains procedures to verify the performance of the U3606B and to
perform adjustments (calibration) where necessary.
– The performance verification tests allow you to verify that the instrument is
operating within its published specifications.
– The adjustment procedures ensure that the instrument remains within its
specifications until the next calibration.
Closed-case calibration
The instrument features closed-case electronic calibration. In other words,
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, after a Factory Reset (*RST command), or
after an Instrument Preset (SYSTem:PRESet command).
Keysight calibration services
When your instrument is due for calibration, contact your local Keysight Service
Center to enquire about recalibration services.
Calibration interval
The multimeter should be calibrated on a regular interval determined by the
measurement accuracy requirements of your application.
A 1-year interval is recommended for the most demanding applications, while a
2-year interval may be adequate for less demanding applications. Keysight does
not recommend extending calibration intervals beyond 2 years for any application.
Ensure that you have read the “Test Considerations” on page 25 before
calibrating the instrument.
