Accuracy Performance Tests

This accuracy performance test assumes you have completed "Initializing the
Performance Test Setup" above. Do not begin this test until the instrument has
been temperature stabilized for a minimum of 30 minutes. Do not use the
instrument front panel monitor function for performance testing; use the higher
resolution Spy window at the host computer, as specified in procedures. The
Accuracy Performance Tests include the following:
Volts DC Accuracy Test
Volts AC Accuracy Test
Frequency Accuracy Test
Analog Channel Integrity Test
Computed Channel Integrity Test
Thermocouple Temperature Accuracy Test
Open Thermocouple Response Test
2-Wire Resistance Accuracy Test
4-Wire Resistance Accuracy Test
RTD Temperature Accuracy Test (Resistance Source)
RTD Temperature Accuracy Test (DIN/IEC 751 RTD Source)
Specific tests for current dc are not included since these functions are derived
from volts dc.
