SECTION I
IDENTIFICATION AND DESCRIPTION
calibration of Dc Transfer Standard, John Fluke Models 730A and 730A/AB. The
manufacturer's instruction manuals were used as the prime data source in compiling
these instructions. The dc transfer standard 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 4
hours, using the dc and low frequency technique.
2. Calibration Data Card, DA Form 2416
prescribed by TM 38-750. DA Form 2416 must be annotated in accordance with TM 38-
750 for each calibration performed.
b. Adjustments to be reported on DA Form 2416 are designated (R) at the end of the
sentence in which they appear. When adjustments are in tables, the (R) will follow the
designated adjustment. Report only those adjustments made and designated with (R)
pertain to this calibration are listed in table 1.
NOTE
For calibration of model 730A to be valid, the TI ∆E control
must be set to the last 3 digits of the value of standard cell
used in the calibration.
