Introduction
Use the procedures in this section to calibrate the 2701. Calibration procedures include:
•
Comprehensive calibration: Usually the only calibration required in the field.
•
Manufacturing calibration: Usually only performed at the factory (unless the unit has been
repaired).
•
7700 calibration: Covers calibration procedures specific to 7700 cards.
The information in this section is intended only for qualified service personnel. Do not
attempt these procedures unless you are qualified.
All the procedures require accurate calibration equipment to supply precise DC and AC voltages, DC
and AC currents, and resistance values. Comprehensive calibration can be performed any time by an
operator either from the front panel or by using the SCPI commands sent either over the ethernet port
or the RS-232 port. DC-only and AC-only calibration may be performed individually.
Environmental conditions
Conduct the calibration procedures in a location that has:
•
An ambient temperature of 18 °C to 28 °C (65 °F to 82 °F).
•
A relative humidity of less than 80% unless otherwise noted.
