TB 9-6625-2193-35
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification. This bulletin
provides instructions for the
calibration of True RMS Voltmeter ME-545/G (Racal-Dana, Model 5002). The
manufacturer's manual and purchase specifications 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. None.
b. Time and Technique.
The time required for this calibration is
approximately 1.5 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).
