Calibration and Verification

Introduction 5-1.
The 5725A is calibrated at the factory before shipping. Calibration is traceable to the
U.S. National Bureau of Standards. All that is required to maintain traceability is to run
5700A calibration to external standards at the beginning of the calibration cycle and do
performance verification every two years. Calibration check and range calibration are
optional procedures that are available for special needs. The 5725A is calibrated
whenever an attached 5700A is calibrated.
Where to Find Further Information 5-2.
Information about 5700A calibration, and therefore 5725A calibration, is contained in
the following sections of the 5700A manual set:
•
Section 7 of the 5700A Operator Manual presents procedures for calibration,
calibration check, and range calibration.
•
Section 1 of the 5700A Operator Manual describes the calibration process and the
theory behind its use to establish traceability to national standards. The same section
includes a description of the calibration check feature, and suggests using it to
develop a performance history for your 5700A. (This applies equally to a 5725A.)
•
Section 3 of the 5700A Service Manual contains a performance verification
procedure recommended every two years to maintain traceability.
