Calibration Overview
This manual contains procedures to verify the U1270 Series
handheld digital multimeters performance and to perform
adjustments (calibration). The performance test procedures
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.
Agilent calibration services
When your instrument is due for calibration, contact your
local Agilent Service Center to enquire about recalibration
services.
NOTE
Ensure that you have read the “Test Considerations” on page 26 before
calibrating the instrument.
