The continuity LED (same as " + DC" LED) will come "On" when resistance between prods is 500K ohms or less. Full brightness of the continuity LED occurs when the resistance between prods is 300K ohms or less. [. . . ] The terminal which does not give a voltage indication, but does give a continuity indication, is the grounded side. · Testing for 25 to 60 Cycle Frequency Place tester between each side of AC line. 60 cycle current is indicated by a higher frequency hum and more rapid vibrations. Continuity LEDwill come "On" if resistance is less than 500K ohms. · · Locating Excessive Leakage to Ground Place tester across the neutral terminal and the ground, only the continuity light should come "On, " indicating neutral and ground are connected. If the " ­ DC" light also comes "On, " there is a 5VAC or greater between neutral and ground indicating a high resistance leakage to ground. High resistance leakage is qualified since a low resistance (high current) leak to ground would open a circuit breaker or blow a fuse.

The duty cycle on:off ratio is 1:7 for 240 volts or less, and 1:40 for 240 volts or greater. Unit may be used for "checking for voltage" without batteries; however, the battery packs must be in place for safe operation. · Always remove right angle plug on lead set prior to removing battery packs. Note: If LEDon the left does not come "On" when it should, check the battery pack on the left. If LED on the right does not come "On" when it should, check the battery pack on the right. Pack may not be fully seated, batteries may not be oriented cor rectly or batteries are bad. Assembly Instructions · Remove lead set plug. Use screwdriver as a lever, inser ting tip in slot at edge of cap and under the battery pack head. · Insert four 1-1/2 volt watch/calculator batter ies (two per each pack), putting negative terminal down as indicated on the side of the battery pack. [. . . ] On Right LED Off Off On On if red prod is on negative, off if prod is reversed. Scale indicates relative voltage. On On On if black prod is on negative, off if it is on positive. On if red prod is on negative, off if prod is reversed.
