Determine Specification Limits for other Calibration Intervals

The verification procedures in this document tests to the 90-day, 99 % confidence specification limits of
the 5560A. For the 5550A and 5540A or for other calibration intervals, you must calculate limits based
upon the specification that was selected. The subsequent examples show how the 1-year specification
limits are calculated. These examples illustrate how to calculate the specifications limits for other
intervals or levels of confidence.
The first example shows how to calculate a specification limit for a particular test point from the
combined specification which is listed as a percentage (or parts per million) of reading plus a floor error
in microvolts, millivolts, microamps, or nanoamps. The component of the specification in parts per
million is referred to as a range specification. The floor specification has the same base units of
measurement as the output value (volts, amps). Do not add a range specification and floor
specification together directly, because they are not in the same units of measurement. To add the two
quantities, convert one quantity so that they are both in the same unit of measurement.
