ND 2838-1 Vol-Con Test Inst sh 11/29/00 11:12 AM Page 1 #61-076, 61-079, 61-080 Vol-Con® Voltage/Continuity Tester Instruction Sheet Usage Instructions · Testing for Continuity ­ no switching required Place tester across terminals (live or dead) of components or circuit to be tested. 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. 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. If the continuity LED does not come "On," the fuse is defective. For locating a blown fuse with the power on, place tester across the "source" side of one fuse and the load side of an adjoining fuse. If no voltage is indicated, the fuse next to the load side prod is blown. If voltage is indicated, the fuse next to the load side prod is OK. Repeat the same test with the prods on the opposite side of the same two fuses to check the other fuse. On a three phase circuit, repeat the same test as above. An indication of no voltage or lower than normal line voltage indicates the blown fuse. · Finding Grounded Side of Line (neutral) Touch one test prod to the ground and the other test prod to each of the line terminals until one is found that does not give a voltage indication, that one is the grounded side of line and the continuity LED should be "On." · Testing for "Grounded"Side of Motor or Appliance With power to motor or appliance "Off," touch one test prod to the frame and the other prod to each of the terminal connections. The terminal which turns the continuity LED "On" is the grounded side. With power to motor or appliance "On," place tester across the frame and to each of the terminal connections. 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. A low frequency hum and slow vibrations indicate 25 cycle current. 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.

Do not operate unit with the batter y pack removed. · Do not use on over 600 volts. 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. · All indications are relative. 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. · 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. Use Union Carbide Corp. Type A76VP, Eveready No. 357 or IDEALNo. 61-201. · Orient the battery packs and snap into tester. Be sure the packs are fully seated. · Press right angle plug on lead set into the bottom of the tester. (Place plug on a bench or solid object and push tester into plug.) This is a tight fit to keep moisture away from pins and to prevent accidental plug release. Be sure the plug is fully seated. · Retract "safety shield" on prod tips Continuity OpenCircuit and lock by rotating. Place one prod into the "probing position" by No Voltage 6-65 AC putting the handle into the prod storage well. Bring the two 6-90 DC exposed tips into contact with each other; the continuity LED (LED to the left) should now be "On." This 65-110 AC assures batteries on the left side are good and your "lead set" is in 90-110 DC good working condition. Always perform this test before using tester. 110-600AC · Test a known live AC circuit such as 120 volts. Both LEDs should be "On"; the neon should have "fired" 110-600 DC if voltage is over 80 and the solenoid coil indicator should be acti vated. Tester is now operational. Neon Bulb Off Off Off Off Left LED On Off On On if black prod is on negative, off if it is on positive. 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. On Scale No movement. No movement. No movement. No movement. On On Little or no movement. Little or no movement. Scale indicates relative magnitude. 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. Warranty limited solely to repair or replacement; no warranty of merchantability, fitness for a particular purpose or consequential damages.
