Models 2510 and 2510-AT Calibration 2-3
Calibration considerations
WARNING The maximum common-mode voltage (voltage between INPUT/OUTPUT
- terminals and chassis ground) is 30V DC. Exceeding this value may
cause a shock hazard.
CAUTION The maximum voltage between INPUT/OUTPUT sense (S) terminals is
1V. Exceeding this voltage may result in instrument damage.
When performing the calibration procedures:
• Make sure that the test equipment is properly warmed up and connected to the
Model 2510 INPUT or OUTPUT terminals as required.
• Always allow the source signal to settle before calibrating each point.
• Do not connect test equipment to the Model 2510 through a scanner or other switching
equipment.
• If an error occurs during calibration, the Model 2510 will generate an appropriate error
message. See Appendix B for more information.
Calibration cycle
Perform calibration at least once a year to ensure the unit meets or exceeds its specifications.
Recommended calibration equipment
Table 2-1 lists the recommended equipment for the calibration procedures. You can use
alternate equipment as long that equipment has specifications at least as good as those listed in
the table. For optimum calibration accuracy, test equipment specifications should be at least
four times better than corresponding Model 2510 specifications.
