GME MT160 User s Manual Rev 1 2 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 if the equipment is turned off Limited One Year Warranty GME Technology warrants to the origina2.
