TB 9-6695-301-50
IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
calibration of Torque Cells, MIS-26485, Type I (Lebow, Model 2133 Series), Torque Cell
MIS-26485 Type II class I (Lebow, Model 2351-102) Load Cells, MIS-26331 (Ametek
Aerospace Model USP1 Series), and Toroid Corp., Model 35-133BCF60K, (MIS-26331TY4),
and Force/Torque Indicator MGCPlus (13589298) . The manufacturer's manual was used
as the prime data source in compiling these instructions. The equipment being calibrated,
torque and load cells with force/torque indicator MGCPlus (13589298) 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 10
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.
