TM 5-6635-386-12&P NOTE Pushing any Operations key will immediately restart tester and will supersede prior command. D - DATA = Displays Density count. M - DATA = Displays Moisture count. D - STD = Displays Density standard count. M - STD = Displays Moisture standard count. Upon initial operation after a period of nonuse, press the CLEAR key to clear out any unwanted commands. Press any of the four OPERATIONS keys to start the tester for normal density and moisture counting. All displays will be normalized to a 1/4 minute count base for simplicity of computation. At the completion of any count cycle, the tester will "beep-beep" rapidly for ten beeps. During the count cycle, a pulsing "beep" will be heard If the batteries are low, but still useable, an "L" will appear in the display window. If the batteries are below acceptable charge level, the "L" will display, but the tester will "Cutout" and will not operate. Recharge the tester overnight when the batteries indicate "L" or low.
