IDENTIFICATION AND DESCRIPTION
1. Test Instrument
Identification. This bulletin provides instructions for the
calibration
of the Precision Component Analyzer, Wayne Kerr, Model, 6425B. 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. None.
b. Time and Technique. The time required for this calibration is approximately 4
hours, using the dc and low frequency technique.

EQUIPMENT REQUIREMENTS
4. Equipment
Required. Table 2
identifies the
specific equipment to be
used in this
calibration procedure. This equipment is issued with Secondary Reference Calibration
Standards Set NSN 4931-00-621-7878. Alternate items may be used by the calibrating
activity. The item selected must be verified to perform satisfactorily prior to use and must
bear evidence of current calibration. The equipment must meet or exceed the minimum use
specifications listed in table 2. The accuracies listed in table 2 provide a four-to-one ratio
between the standard and TI. Where the four-to-one ratio cannot be met, the actual
accuracy of the equipment selected is shown in parenthesis.
5. Accessories Required. The
accessories required for this
calibration are common
usage accessories, issued as indicated in paragraph 4 above, and are not listed in this
