TB 9-6625-2279-35
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification. This bulletin
provides instructions for the
calibration of Volt-Ohm-Milliammeter, Soltec, Model HM-102S. The manufacturer's
manual was used as the prime data source in compiling these instructions. The
equipment being calibrated 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 1
hour, using the dc and low frequency technique.
2. Forms,
Records, and
Reports. Forms, records, and
reports required for
calibration personnel at all levels are prescribed by TB 750-25.
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-286. 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.
5. Accessories Required. The
accessories required for this
calibration are
common
usage accessories issued as indicated in paragraph 4 above and are not listed in this
calibration procedure.
