1. User s Manual Rev 1 3 TEST INSTRUMENT SAFETY GUIDELINES WARNING An electrical shock of over 10 milliamps of current to pass through the heart will stop most human heartbeats Voltage as low as 35 volts dc or ac rms should be considered dangerous and hazardous since it can produce a lethal current under certain conditions Be sure to observe following safety precautions l Do not expose high voltage needlessly in the equipment under test Remove housings and covers only when necessary Turn off equipment while making test connections in high voltage circuits Discharge high voltage capacitors after removing power If possible familiarize yourself with the equipment being tested and the location of its high voltage points However remember that high voltage may appear at unexpected points in defective equipment Use an insulated floor material or a large insulated floor mat to stand on and an insulated work surface on which to place equipment make certain such surfaces are not damp or wet When using a probe touch only the insulated portion Never touch the exposed tip portion When testing ac powered equipment remember that ac line voltage is usually present on some power input circuits such as the on off switch fuses power transformer etc any time the equipment is connected to an ac outlet even 1f the equipment is turned off Limited One Year Warranty GME Technology warrants to the original purchaser that this2. 100 saturation Colors bars include White Yellow Cyan Green Magenta Red Blue and Black The COLOR BARS video pattern serves as the fundamental pattern used for most testing troubleshooting and adjustments in video equipment Use this test pattern to check and test the video device s ability to produce fully saturated primary and secondary colors It is often used as the reference for color adjustment and compensation When troubleshooting analysis of the colors bars pattern helps television service personnel to pinpoint color related problem to specific circuits This pattern can also be use as a reference for troubleshooting color amplifier or color demodulator problems inside the display device www gmetechnology com 7 CROSS HATCH amp DOT The CROSS HATCH patterns display a series of horizontal and vertical straight white lines that forms a grid of 12 x 8 squares of the same size The CROSS HATCH patterns are used to check and adjust dynamic convergence of the display Observe the horizontal and vertical lines to detect color fringing resulting from misconvergence An example that the display is misconverged is when the white lines in the white CROSS HATCH pattern become separated Red Green and Blue lines Adjust the displays RGB convergence control to align the colors to overlap so the horizontal and vertical lines appear as white lines This pattern can also provide a convenient reference for making vertical and horizontal linea
