Adjustments
Introduction
This chapter contains procedures for adjusting the calibration constants in
the HP E1418A. Run the Performance Tests (described on Chapter 4)
before any adjustments to characterize the module. Run the Performance
Tests after any adjustments to verify the adjustments made. The module
should be adjusted following any reconfiguration or repair.

Calibration Services
Contact the local Hewlett-Packard Service Center for low cost calibration
services. The HP E1418A is supported on automated calibration systems
which allow calibration at competitive prices. Calibrations to
MIL-STD-45662 are also available.
Calibration Interval
The HP E1418A 8/16 Channel D/A Converter Module should be calibrated
on a regular interval determined by the accuracy requirements of you
application. Hewlett-Packard recommends calibration every 90 days for
most applications. Demanding applications may require a daily calibration
cycle. Hewlett-Packard does not recommend extending the calibration
interval beyond one year in any application.
Whatever calibration interval you use, Hewlett-Packard recommends that a
complete adjustment be performed. This increases confidence that the
module will remain in specification for the next calibration interval and
provides the best measure of the module’s long-term stability. Performance
Verification Test data can be used to extend or determine future calibration
intervals.
