Calibration Shift Results
The Calibration Shift report presents all adjustments made to stored zero-offset and gain
constants, as a result of any drift detected at the most recent calibration. This report is
available and valid at any time.
The report contains this information:
• Heading containing the date and time the report was saved, the user report string, and
the installed version of the Calibrator software.
• Modules present (installed or attached) including any attached amplifiers
• Most recent calibration dates and temperatures
• Values of externally-calibrated internal references including the resistance reference,
which is the average of the actual-to-nominal ratios of the 100 Ω, 190 Ω, 1 kΩ,
1.9 kΩ, 10 kΩ, 19 kΩ, 100 kΩ, and 190 kΩ resistors.
• DC voltage output shifts for each range
• AC voltage output shifts for each range. A gain shift for all frequencies is shown
along with shifts at selected frequencies for each range.
• Current output shifts for each range (ac and dc)
• Resistance shifts for each value
• 5725A Amplifier output shifts (if attached)
• Wideband AC Module (Option 5730A/03 or 5730A/05) output shifts (if installed)
The shifts of references and outputs are given both as absolute shifts in V, A, or ohms,
and also (for non-zero magnitudes) as shifts relative to the previous value, in parts per
million (ppm) or percent (%).
The specified accuracy for the output is also shown, and the ratio of the shift to that
accuracy in percent.
The Calibration Shift report file name is CSyymmdd.CSV, where yymmdd is the date
today. For example, a calibration shift report compiled on October 28, 2013 would be
saved to CS131028.CSV.
