The key to eliminating an error is knowing its source and type along with its polarity and
magnitude. Generally, the source is simple to detect and is represented by the specific
parameter. The type is usually a function of the instrument’s design and manufacturing
process. Within a given instrument, an error can be either random or systematic, as well
as random or systematic within the instrument’s population. The user is free to consult
Fluke for recommended methods of minimizing error source contributions.
In summation, total error can and should be managed by the control of the three general
error sources: Input Specifications, which includes the user’s chosen calibration standards;
General Specifications, which includes the user’s chosen processes; and Performance
Specifications, which includes the user’s chosen applications for the instrumentation. The
parameters and value limits listed in the following specifications indicate the product
line’s general acceptance limits and are not a report of any unit’s specific error
contribution. Any parameter exceeding the specified limits should be considered in need
of maintenance.
