Q:This is giving me a false positive for contact with any metal. Am I doing something wrong or is this product just very inaccurate?
by|May 22, 2023
1 Answer
Answer This Question

A:  Dear customer, Please ensure that you perform a self check of the functionality of the device before use to ensure it is working properly: Set the selector switch to the 0 position. Use one hand to hold the tip and the other hand to touch the metal contact on the side of the device. the Red indicator should light. Next, set the selector switch to the L/H position. Use one hand to hold the tip and the other hand to touch the metal. If the green indicator illuminates and the buzzer beeps, the device is functioning correctly.

        Q:Will this detect power in a low voltage connection(doorbell)
        by|Sep 23, 2021

        Answer This Question

        A:  The lowest voltage this unit will detect is 70 volts, if the voltage of your doorbell is less it will not detect it. Mike

        A:  Commercial Electric NCS-8904R non-contact Tester with Screw Driver can measure AC voltage from 70 to 250. Please see the manual page 4.

        by|Jul 19, 2023

          A:  Seems to.

          by|Feb 8, 2022

          A:  Most door bells operate at a voltage lower than 70 Volts, newer doorbells can take up to 24 volts. This product has a minimum voltage range of 70V so it will not detect anything lower than that.

            A:  Not necessarily. Look for YouTube video about how to use it and read the reviews. I returned mine unopened,

            While trying to satisfy the requirements of both a contact and non-contact voltage measuring device, this item accomplishes both, but neither well. The instructions provided are somewhat convoluted and, in some cases, erroneous. This is a simple device that is generally used to quickly verify if circuits are live or not. A label on the tool instructs the user to test on a known live circuit first, yet the instructions give several optional methods of performing “self-tests”, one which is flawed by the variable of grip and skin moisture the other due to the wording of the instructions. The “switch off” self test, where on grabs the exposed tip with one hand and the side contact plate with the other only works if your skin is relatively moist and your grip firm. The other method, with the tool in the “on” (high or low sensitivity) position references “both green lights illuminated”….when there is only one green light. The choice of a green light (LED) as an indicator of voltage present is unfortunate, as the power industry generally considers green indicators to show an open or de-energized state. While the tool can be used in the “non-contact” mode, with the cap in place (covering the exposed conductive tip) the cap is not captive and could be easily misplaced. A white LED “flashlight” is incorporated (which requires the tool be in one of the two “on” modes (H/L). The contact tip is shaped much like a screwdriver, however, since the instructions make no mention of being used in this capacity, one must assume that to do so may damage the housing which secures the tip. As this tool lacks intuitiveness and repeatable response under varying conditions it is certainly not the best solution out there.

            This product seems to work okay but the manual is really confusing so it is hard to tell if I’m using it correctly. On the switch there is an O, L & H setting. What do the different settings mean? Maybe off, low and high. Some examples of my confusion from the manual. On page 5 it says: “The red indicator light (B) illuminates indicating the presence of AC voltage.” And then: “Whenever neutral or earth (ground) is disconnected, the red light indicator light (B) will also illuminate…” So if the red light illuminates is it just AC voltage or disconnected neutral or ground? On the bottom of the same page it talks about “Testing AC Voltage using the non-contact method…”, but then it says to “…gently trace the tip (A) of the tester onto the wire.” So if you are touching the wire how is it non-contact? On page 6 it says: “To reduce the sensitivity, place your other hand onto the object you are testing.” Aren’t you testing a wire with AC voltage? Why would you want to place your hand on the wire? On page 7 the instructions say to replace the small watch type batteries you should: “Use a screwdriver to unscrew and remove the battery cover…” What you are actually doing is removing the whole side and the clip comes off too. Also be careful because the two screws are different. I would prefer a AAA battery and an easier way to change it but I suppose they take up more room. It is really inexpensive so I suppose you can’t expect too much.

            Constant false positives
            Doesn’t work, gives constant false positives for clearly dead wire.
