Keithley 2000 Calibration Manual

Introduction
Use the procedures in this section to calibrate the Model 2000. Calibration procedures in-
clude:
•
Comprehensive calibration: Calibrate DC and AC voltages, DC and AC currents, and
resistance values.
•
Manufacturing calibration: Usually only performed at the factory.
WARNING This information in this section is intended only for qualified service person-
nel. Do not attempt these procedures unless you are qualified to do so.
All the procedures require accurate calibration equipment to supply precise DC and AC volt-
ages, DC and AC currents, and resistance values. Comprehensive AC and DC calibration can be
performed any time by a technician either from the front panel, or by using the SCPI commands
sent either over the IEEE-488 bus or the RS-232 link.
NOTE Manufacturing calibration is required in the field only if the Model 2000 has been re-
paired.
This section includes the following information:
Environmental conditions: Explains the type of environment needed for calibration.
Calibration considerations: Summarizes test conditions to observe when performing cali-
bration.
Calibration code: Explains how to enter the calibration code to unlock Model 2000 calibra-
tion.
Comprehensive calibration: Summarizes the calibration cycle and also lists recommended
comprehensive calibration equipment.
Front panel calibration: Provides the calibration procedures using the front panel.
SCPI command calibration: Provides the detailed procedures for calibrating the Model
2000 using SCPI commands.
Manufacturing calibration: Explains the manufacturing calibration procedure using both
the front panel and SCPI commands.
