IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Ac Calibrator, Fluke, Model 5200A and Precision Power Amplifiers, Fluke,
Models 5215A and 5205A. The manufacturers' manuals were used as the prime data
sources in compiling these instructions. The equipment being calibrated will be referred to
as the TI (test instrument) throughout this bulletin.
a. Model Variations. Variations among models are described in text.
b. Time and Technique. The time required for this calibration is approximately 6
hours, using the dc and low frequency technique.
2. Forms, Records, and Reports
a. Forms, records and reports required for calibration personnel at all levels are
prescribed by TB 750-25.
b. Adjustments to be reported are designated (R) at the end of the sentence in which
they appear. When adjustments are in tables, the (R) follows the designated adjustment.
Report only those adjustments made and designated with (R).
3. Calibration Description. TI parameters and performance applications which pertain
to this calibration are in table 1.
