Users Manual

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.
