SECTION I
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Voltage Divider, Beckman Models T-10-A Series and TA-1001; ESI Models
DP211, DP311, DV411, and DV412; and General Radio Model 1454A. The manufacturers'
instruction manuals were used as the prime data sources in compiling these instructions.
The voltage divider will be referred to as the TI (test instrument) throughout this bulletin.
a. Model Variations. Variations among models are described in the text.
b. Time and Technique. The time required for this calibration is approximately 4
hours per instrument, using the dc and low frequency technique.
2. Calibration Data Card (DA Form 2416). Maintenance forms, records, and reports
which are to be used by calibration personnel at all calibration levels are listed in and
prescribed by TM 38-750.
3. Calibration Description. TI parameters and performance specifications which
pertain to this calibration are listed in table 1.
