IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
calibration of Voltmeter Frequency Selective AN/USM-490( ), and Selective Level Meter,
Hewlett-Packard, Models 3586B and 3586C w/Options 001, 003, and 004.
The
manufacturer's manual was used as the prime data source 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 12
hours, using the dc and low frequency technique.
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 adjustments.
Report only those adjustments made and designated with (R).
pertain to this calibration are listed in table 1.
