TB 9-6695-242-24
IDENTIFICATION AND DESCRIPTION
1. Test Instrument
Identification.
This bulletin provides instructions for the
calibration of Dial Indicating Tensiometer, Dillon, Model AN-ELEX and Dynamometer,
Dillon, Model AN-IONO. The manufacturers' manuals 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. Some TIs have a 5 inch dial and some have a 10-inch dial.
Other variations are described in text.
b. Time and Technique. The time required for this calibration is approximately 2
hours, using the physical technique.
2. Forms,
Records, and
Reports
a. Forms records, and
reports required for calibration personnel at all
levels are
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).
3. Calibration

EQUIPMENT REQUIREMENTS
4. Equipment
Required. Table 2 identifies the
specific equipment to be
used in this
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Set AN/GSM-287. Alternate items may be used by the calibrating activity. The
items selected must be verified to perform satisfactorily prior to use and must bear evidence
of current calibration. The equipment must meet or exceed the minimum use specifications
listed in table 2. The accuracies listed in table 2 provide a four-to-one ratio between the
standard and TI.
