5725A
Instruction Manual
1-6
5700A Service Manual 1-8.
The 5700A Service Manual is a maintenance guide for the 5700A. The following 5725A
topics are included in the 5700A Service Manual:
• Specifications for both the 5700A and 5725A (these same specifications are in this
Instruction Manual)
• Full verification of the 5700A and 5725A (recommended every two years)
• Calibration of the 5700A and 5725A (same procedure as in the 5700A Operator
Manual)
Specifications 1-9.
Specifications are valid after allowing a warm-up period of 30 minutes, or if the 5725A
has been recently on, twice the time the 5725A has been turned off. For example, if the
5725A has been turned off for five minutes, the warm-up period is ten minutes.
Absolute uncertainty includes stability, temperature coefficient, linearity, line and load
regulation, and traceability to external standards. You do not need to add anything to
absolute uncertainty to determine the ratios between 5700A/5725A uncertainties and the
uncertainties of your calibration workload.
Relative uncertainty specifications are provided for enhanced accuracy applications.
These specifications apply when range constants are adjusted (see "Range Calibration"
in the 5700A Operator Manual). To calculate absolute uncertainty, you must combine
the uncertainties of your external standards and techniques with relative uncertainty.
Secondary performance specifications and operating characteristics are included in the
uncertainty specifications. They are also provided separately for special calibration
requirements such as stability or linearity testing.
