IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
calibration of Aircraft Weighing Kit, BLH, Model C1; Evergreen, Model Roadrunner II; and
Revere, Models C7500, C46500, C55800-4-25, C55800-3-50, CS7, 155800-00, 155800-01,
and 155800-03. The manufacturers' manuals, TM 55-6670-200-14&P, and TM 55-6670-201-
13&P were used as the prime data sources 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.
b. Time and Technique. The time required for this calibration is approximately 3
hours, using the physical technique.
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).
pertain to this calibration are listed in table 1.
