Documents Flashcards Grammar checker. Handle the test sample by the active colored end. Place the test sample next to your skin.
Keep the test sample in the case when not in use. Assure that the test sample is securely attached to the radiac set case with the chain provided.
Handle only as necessary. Should you receive spare tubes by mistake, return to stock immediately. Never attempt to replace a tube in the radiacmeter. Refer to TM for specific instructions on the control, safe handling, inspection, storage, and disposition of the test sample.
If you find anymistakes or if you know of a way to improve the procedures, please let us know. A reply will be furnished to you. This manual supersedes so much of TM 2 Septemberincluding all changes that pertains to the Organizational Maintenance.
Detects and measures beta and gamma radiation together of gamma radiation alone. It is not necessary to show a new design or list a better way to perform a procedure, just simply tell why the design is unfavorable or why a procedure is difficult. A reply will be furnished directly to you. Major Components All Components of the radiac set are contained in a carrying case.
Each component is shown below. A full description of the radiac set and its individual components can be found in TM The Radiac Set consists of: Location of Components in Case and Equipment Labels Location of components while stored in the carrying case are shown below. Nomenclature plates and equipment labels are also identified.
Beta and tions together gamma Types of gamma radia- or radiation alone. Six BA Batteries 1. Activates batteries and controls sensitivity of meter. Supply operating power to the radiacmeter.
Supply required voltages to the tubes in the probe and to the amplifier and pulse shaping circuit. Keep power supply circuit voltages constant so that radiacmeter operates properly.
Contains two Geiger-Mueller tubes which detect radiation. One tube is associated with range switch position to 50, the other dq position 5 or 0.
Takes pulses from the probe and com verts them to constant amplitude pulses which are applied to the meter circuit. Indicates the amount of radiation detected by the probe on a scale. Provides an audible indication of ca detected by the probe. Repair parts are listed and illustrated in the repair parts and special tools lists, TM P, covering organizational maintenance for this equipment.
Inspect the equipment for damage incurred during shipment. Check the equipment against the packing list to see if the shipment is complete. Report all discrepancies in accordance with the instructions of TM Check to see whether the equipment has been modified. If the Radiac Set has been modified, then an MWO data plate should appear on the case next to the nomenclature plate.
Case Harness 1 Inspect the harness for tears. Case Headset 1 Inspect for dirt, fungus and grease. Inspect for tears in the cables.
Radiacmeter Probe 1 Inspect for grease, dirt and fungus. Case Radiacmeter 1 Inspect for grease, dirt and fungus. Check that range switch is not cracked or missing.
ELECTRONIC DA FORM INSTRUCTIONS
Use Table to perform preventive maintenance checks and services to be sure that the Radiac Set is always ready for use. If the Radiac Set fails to operate, then follow the maintenance instructions in paragraph Troubleshooting. If surface area missing paint is larger than one square inch, touch up painting is required.
Inspect glass surfaces for cracks or scratches that would impair ability to obtain accurate readings.
Inspect the battery compartment for fodm. Check rubber gaskets for wear, frays or tears, and replace if necessary. Check for worn threads and broken or worn gaskets.
Check that the knob is not cracked or missing. Check that the knob is not loose or binding. Replace or repair as necessary. Check for frays, 2028–2, or cracks in the probe and headset cables. Check for frays or tears. Check for two complete clip fasteners. Check for cracks or breaks.
Inspect for broken clasps or handles. This manual cannot list all malfunctions that may occur, dorm all tests or inspections and corrective actions. If a malfunction is not listed or is not corrected by performing listed ca actions, notify your Supervisor and evacuate to higher maintenance for repair.
Remove battery compartment cover by loosening three captive screws and check the rubber gasket on the mounting panel. Remove two screws securing handle to cover and check both gaskets. Check operation of switch at each position to check for looseness or binding.
If switch binds, loosen the setscrew gradually until the switch turns 208-2 and stops at each setting. If the switch is loose, tighten setscrew so the switch stops at each setting. 202-2 not use excessive force to tighten setscrew. The column gives the area of the damaged item. The column describes the steps to be followed in order to replace and repair the damaged item. If the rubber gasket is damaged, then remove the gasket.
Make sure that the gasket is seated properly in the recessed groove and remove any excess cement from around the 2028. Tighten the screws securely in order to maintain a watertight battery compartment. Do not tighten too tightly or damage may result to the rubber gaskets. Inspect captive screws for damage broken threads or cracks. Do not tighten the screw too tightly or damage may result to the screw.
Cleaning To clean the Radiac Set surface, wipe with a soft, damp cloth to remove grease, dirt 2028–2 fungus. Painting 1 Check painted surfaces for missing, blistered or chipped paint. If the surface area missing paint is larger than 1 square inch, touch up painting is required. Preparation for The following items must be completed or considered prior to storing the equipment: The storage area must be secure and prevent items from being stolen.
Covered storage is required. Equipment that is inoperative cannot be stored. Perform the operational check routine on the equipment prior to storage.
The equipment in storage must be able to be put into operation within 24 hours. Batteries must always be removed before the Radiac Set is placed into any type of storage. Administrative storage covers the storage of equipment which can be readied for mission performance within 24 hours. Before placing an item in administrative storage, the next scheduled preventive maintenance checks and services should be performed, all known fodm corrected, and all current modification work orders applied.
The administrative storage site should provide required protection from the elements and allow for visual inspection and exercising when applicable. Place the radiacmeter in the case.
TM Fodm for destruction of electronic materiel to prevent enemy use Electronic Command. 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: T E S T – 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. ADJUST – To maintain, within prescribed limits, by bringing into proper or exact position, or by setting the operating characteristics to the specified parameters.
ALIGN – To adjust specified variable elements of an item to bring about optimum or desired performance. 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 compared. INSTALL – The act of emplacing, seating, or fixing into position an item, part, module component or assembly in a manner to allow the proper functioning of the equipment or system.
R E P L A C E – The act of substituting a serviceable like type part, sub-assembly, or module component or assembly for an unserviceable counterpart.
