TB 9-6625-2214-24
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Universal Frequency Counter, Hewlett-Packard, Model 5335A Options 010,
020, 030, and 040. 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, tables, and
figures.
b. Time and Technique. The time required for this calibration is approximately 2
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 specifications which
pertain to this calibration are listed in table 1.
