2 Performance Test Calibration
Calibration Overview
Closed - case electronic calibration
The instrument features a closed- case electronic calibration.
No internal mechanical adjustments are required. The
instrument calculates the correction factors based upon the
input reference value that you set. The new correction
factors are stored in nonvolatile memory until the next
calibration adjustment is performed. The nonvolatile
EEPROM calibration memory does not change when power
has been off or after a remote interface reset.
Agilent technologies calibration services
When your instrument is due for calibration, contact your
local Agilent Service Center for a low- cost recalibration. The
U2741A is supported on automated calibration systems,
which allows Agilent to provide this service at competitive
prices.
