Electronic Measurement Equipment Mechanic

This position is located in the Joint Forces Headquarters-State Logistics Directorate (J-4) Surface Maintenance Facility. The primary purpose of this position is to perform calibration diagnostics repair and certification of electronic mechanical and radiation Test Measurement and Diagnostic Equipment (TMDE).

• Calibrates and repairs TMDE within support capability and authority including various levels of calibration as designated in technical bulletins manuals etc. Performs functional electronic physical and radioactive testing involving interpretation and analysis of measurement data in accordance with cyclic inspection requirements. Aligns troubleshoots tests inspects repairs modifies calibrates and certifies precision measurement equipment such as multimeters microwave equipment oscilloscopes temperature analyzers mercurial barometers gage blocks and micrometer caliper dimensional equipment digital voltmeters signal generators torque wrenches pressure gauges torque testers weight scales electronic counters radiation monitors radix calibrators and radiation dosimeters. 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.
• 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.
• 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.
• 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. Makes radiation calculations/readings at various distances from the standard ensuring radiation equipment is operating in specified parameters. Performs contamination/radiation surveys on radiation equipment to control/eliminate radiation leakage/contamination.
• Follows appropriate safety procedures with special care being exercised while calibrating high voltage radio frequency radioactive sources and high-pressure instruments and gages. Performs and interprets wipe tests on radiation sources for possibility of radiation hazards. Familiar with and abides by all Federal and State regulations concerning handling transportation and disposal of radioactive waste or devices.
• Performs other duties as assigned.

• NATIONAL GUARD MEMBERSHIP IS REQUIRED. If you are not sure you are eligible for military membership please contact a National Guard recruiter prior to applying for this position.
