Section I INTRODUCTION
This appendix provides a summary of maintenance operations for the test set. It authorizes categories of maintenance
for specific maintenance functions on repairable items and components and the tools and equipment required to perform
each function. This appendix may be used as an aid in planning maintenance operations.
Maintenance functions will be limited to and defined as follows:
a. Inspect. To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical
characteristics with established standards through examination.
b. Test. To verify serviceability and to detect incipient failure by measuring the mechanical, or electrical
characteristics of an item and comparing those characteristics with prescribed standards.
c. Service. Operations required periodically to keep an item in proper operating condition, ie, to clean
(decontaminate); to preserve; to drain; to paint; or to replenish fuel, lubricants, chemical fluids, or compressed air
d. Adjust. To maintain, within prescribed limits, by bringing into proper or exact position, or by setting the operating
characteristics to specified parameters.
e. Aline. To adjust specified variable elements of an item to bring about optimum or desired performance.
f. Calibrate. To determine and cause corrections or adjustments to be made on Instruments or test, measurement,
and diagnostic equipment used in precision measurement. Consists of comparisons of two instruments, one of which is a
certified standard of known accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being
g. Install. The act of emplacing, seating, or fixing into position an Item, part, or module (component or assembly) In
a manner to allow the proper functioning of the equipment or system. h. Replace. The act of substituting a serviceable
like-type part, subassembly, or module (component or assembly) for an unserviceable counterpart.
i. Repair. The application of maintenance services (inspect, test, service, adjust, aline, calibrate, install, or
replace) or other maintenance actions (welding, grinding, riveting, straightening, facing, remachining, or resurfacing) to
restore serviceability to an item by correcting specific damage, fault, malfunction, or failure in a part, subassembly,
module (component or assembly), end item, or system.
That maintenance effort (service/action) necessary to restore an Item to a completely
serviceable/operational condition as prescribed by maintenance standards (ie, DMWR) in appropriate technical
publications. Overhaul is normally the highest degree of maintenance performed by the Army. Overhaul does not
normally return an item to a like-new condition.
