[. . . ] Reversing prods will verify continuity versus low volt DC. · Locating Blown Fuses (single phase, three phase and DC) Turn Power Off. Place tester across the suspected fuse to perform continuity check. If continuity LEDcomes "On, " the fuse is good. [. . . ] 60 cycle current is indicated by a higher frequency hum and more rapid vibrations. Checking Continuity of Cords, Motors, Appliances, etc. Remove power source and place tester across circuit to be tested. 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. ND 2838-1 Vol-Con Test Inst sh 11/29/00 11:12 AM Page 2 Cautions · To avoid the risk of electrical shock, disconnect test leads before removing the batter y pack. Do not operate unit with the batter y pack removed. This instrument is for intermittent service only. The duty cycle on:off ratio is 1:7 for 240 volts or less, and 1:40 for 240 volts or greater. Fifteen seconds is the maximum "On" time. For determining the nominal line voltage only. · Do not use unit with battery packs removed. 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. Remove the two battery packs adjacent to the lead set, plug opening. Use screwdriver as a lever, inser ting tip in slot at edge of cap and under the battery pack head. A light force will pop the pack loose for easy hand removal. [. . . ] On On if black prod is on negative, off if it is on positive. On Right LED Off Off On On if red prod is on negative, off if prod is reversed. On On if red prod is on negative off if prod is reversed. No movement. On On Little or no movement. [. . . ]
