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:

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.
