Analyzes and isolates component malfunctions; calculates and determines tolerances; and performs tests and calibrations in accordance with instructions, which are often vague and incomplete, and may require the preparation of diagrams and instructions to facilitate the calibration action. (2) Sets up system test sets and various types of test equipment such as frequency meters, standing wave ratio meters, radio frequency (RF) power meters, function/ arbitrary waveform generator, distortion analyzers, time frequency work stations, oscillators, voltmeters, electronic counters, oscilloscopes, attenuators, decade resistors and capacitors, signal generators, stroboscope, tachometers, pneumatic and hydraulic pressure standards and other physical and electronic tests.

Diagnoses equipment, makes repairs, and replaces defective parts/components such as integrated circuits, printed circuit boards, electronic condition coils, radiation detector boards/circuits, crystals, transistors, tubes, transformers, condensers, diodes, relays potentiometers, and related components. (3) Following repair, tests by applying signals in known amplitude and wave shape into oscilloscopes to observe wave pattern.

Isolates faults by taking measurements and comparisons in voltage, amperage, ohms, henries, power factor, watts, temperature, humidity, microns, foot-pounds, decibels, sensitivity, noise, stability, Voltage Standard Wave Ratio (VSWR), impedance, phase, absolute pressure, time intervals, displacement, flow rate, etc., to determine performance of equipment. If signal is distorted, traces it through electronic stages to locate malfunctioning part.

Checks sweep rate by feeding known signal to an oscilloscope and observing wave pattern to correct shape and size. Operates equipment to complete range checking for proper operation of positioning controls. Adjusts with trimmer potentiometers; and if calibration is still not possible, adds or removes sufficient resistance to permit balancing of circuit. As needed, contacts the using organization to obtain information concerning the nature of the malfunction.

Uses equipment schematics to analyze circuits by preparing block diagram showing major components such as amplifiers, filters, oscillators and indicators. (4) Determines purpose in operation characteristics of each major section.

Refers to technical manuals and manufactures specifications to obtain information on operation characteristics of circuit components such as integrated circuits, microprocessors, decoders, latching networks, notch filters, logics, controllers, programmable gain amplifiers, digital displays, transistors, tubes, transformers, coils, relays, motors, and similar devices.

Disassembles, cleans and inspects parts such as printed circuit boards, resistors, capacitors, integrated circuits, relays, chambers, cables, and wiring for evidence or wear or malfunction. Repairs and/or replaces parts as required. Uses special test devices and radioactive samples or other calibrated sources. Tests equipment for sensitivity and correct operation.

Observes necessary precautions as stipulated in operational repair manuals. (5) Completes necessary Army Maintenance Management System (TAMMS), calibration, radiation reports and other records and forms on work completed. Ensures maximum number of weapons systems are operationally ready. Uses TMDE Integrated Maintenance Management Systems (TIMMS) for all supported equipment to track, turn-in, repair, calibrate, and return to the end user in a timely fashion to prevent work stoppages.

Furnishes technical data to the supervisor for inclusion in reports as well as recommending equipment improvement and solutions for unusual problems related to testing and the use of precision TMDE. (6) Follows appropriate safety procedures, with special care being exercised while calibrating high voltage, radio frequency, radioactive sources and high-pressure instruments and gages.
