Appendix D. Field Calibration Verification
This appendix defines testing specifications and procedures for performing Amplitude and
Distortion tests, and Phase Shift tests on configured current and voltage sources.
Testing Specifications
Test specifications for following are provided in this section.
• ”Ambient Accuracy”
• ”Test Setup”
• ”Test Equipment”
Ambient Accuracy
F6300 Test Instruments are normally used in areas where the temperature is between 68 and
86
°F (20-30°C) and the AC power is within ±10% of 115 (or 230) V. Under these conditions, and
when connected to a load that does not exceed the source’s range limits, F6300 AC test signals
are warranted to meet the following accuracy specifications.
Amplitude ±0.03% of range from 0 to 10% of range, and within ±0.3%
of setting from 10 to 100% of range for High Current.
Phase Angle ±0.25 at 50 or 60 Hz.
Distortion 2% maximum at 50 or 60 Hz., 0.1% typical
Test Setup
All Current Sources are measured with either a shunt or ammeter connected across the output.
Test Equipment
All test equipment must be more accurate than the signal being measured, and have a valid
calibration sticker tracing the calibration to the Nation Bureau of Standard references. As a
reference, the instruments used by Doble Engineering for factory calibration of the F6300 are
listed in
Table D.1
.
