b. Time and Technique. The time required for this calibration is approximately 2
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).
