Calibration Procedures
This chapter contains procedures for verification of the instrument’s
performance and adjustment (calibration). These procedures are
required only if the internal DMM is installed. The chapter is divided
into the following sections:
• Agilent Technologies Calibration Services, on page 63
• Calibration Interval, on page 63
• Time Required for Calibration, on page 64
• Automating Calibration Procedures, on page 64
• Recommended Test Equipment, on page 65
• Input connections, on page 66
• Calibration Security, on page 67
• Calibration Message, on page 69
• Calibration Count, on page 69
• Calibration Procedures, on page 70
• Aborting a Calibration in Progress, on page 70
• Test Considerations, on page 71
• Performance Verification Tests, on page 72
• Internal DMM Verification Tests, on page 75
• Optional AC Performance Verification Tests, on page 80
• Internal DMM Adjustments, on page 81
• –10 Vdc Adjustment Procedure (Optional), on page 85
• Plug-in Module Test Considerations, on page 87
• Relay Verification, on page 88
• Thermocouple Reference Junction (Optional), on page 112
• 34907A Analog Output, on page 114
Closed-Case Electronic Calibration The 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 non-volatile memory until the next
calibration adjustment is performed. Non-volatile EEPROM
calibration memory does not change when power has been off or
after a remote interface reset.
