Precise measurements of low power CW electron beam current for the Jefferson Lab Nuclear Physics program have been performed using a Tungsten calorimeter. This paper describes the rationale for the choice of the calorimeter technique, as well as the design and calibration of the device. The calorimeter is in use presently to provide a 1% absolute current measurement of CW electron beam with 50 to 500 nA of average beam current and 1-3 GeV beam energy. Results from these recent measurements will also be presented.

Interpretation of diagnostic signals is incomplete without comprehensive start to end analysis of signal error. Signal error sources are varied and their interactions can lead a misinterpretation of the result and its measured precision. This lecture will review error sources, error propagation, and statistics. Specific examples applicable to accelerator beam diagnostics will be presented.
