Determine Specification Limits for other Calibration Intervals

The verification procedures in this document test to the 90 day 99 % confidence
specification limits. For other calibration intervals, it is necessary to calculate
limits based upon the specification that was selected. The subsequent examples
show how the 90 day specification limits were calculated. These examples
illustrate how to calculate the specifications limits for other intervals or levels of
confidence.
The next 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). It is not appropriate to add a
range specification and floor specification together directly, because they are not
in the same units of measurement. In order to add the two quantities, it is
