18-8 Performance Verification
Performing the verification test procedures
Test summary
•Volts measurement accuracy
• Amps measurement accuracy
• Ohms measurement accuracy
• Coulombs measurement accuracy
If Model 6514 is not within specifications and not under warranty, see the calibration proce-
dures in Section 19 for information on calibrating the unit.
Test considerations
When performing the verification procedures:
• Restore Model 6514 factory front panel defaults and perform input bias current and volt-
age offset calibration as outlined below.
• Make sure that the test equipment is properly warmed up and properly connected to
Model 6514 INPUT jack.
• Be sure test equipment is set up for the proper function and range.
• Allow the input signal to settle before making a measurement.
• Do not connect test equipment to Model 6514 through a scanner, multiplexer, or other
switching equipment.
WARNING The maximum common-mode voltage (voltage between analog common
and chassis ground) is 500V peak, DC to 60Hz sine wave. Exceeding this
value may cause a breakdown in insulation, creating a shock hazard.
CAUTION The maximum input voltage is 250V peak, DC to 60Hz sine wave. Exceed-
ing this voltage may result in instrument damage.
