Non-contact Voltage Testing (NCV)

As many of you may know non-contact voltage sensors (NCV’s) or “voltage sniffers” are strange and mysterious in how they work or in some cases don’t work. Due to the nature of this product and the science behind non-contact voltage testing, sensitivity is always a variable due to the components used and because your body completes the circuit which will affect your readings. We’re going to clear up some of the confusion behind NCV’s in this article, hopefully this will help bring you a better understanding of how they work. Below you’ll find useful tips and tricks for detecting voltage with a non-contact voltage detector.

One of the first things you want to do before you test for voltage at an outlet is disconnect any device that is connected to that specific outlet. This is largely due to the field that electricity creates.  If something is plugged into the outlet, the cord will generally increase the size of the field and make discrete detection difficult at best. The size of the field detected by a non-contact voltage detector can vary significantly in size for a variety of reasons, such as whether the box or cover is metal or plastic. Depending on the fixture (metal or plastic), the field may be greater.

For outlets in a metal box the field would be smaller and greater sensitivity would be required compared to a fixture in a plastic box where less sensitivity is required where the field is larger. GFCI outlets will generally have a larger field, making discrete detection even more difficult. The detection distance for a standard (non-GFCI) outlet, plastic cover, plastic box, should be less than 1 inch. As a result, to determine what is hot in an outlet using a (non-adjustable) voltage detector may require a technique that may not be obvious. We believe the natural way for most people to use a non-contact voltage detector is to approach the outlet directly from the front, as if one were plugging something into the outlet.

Direct

When the AC field is relatively large (plastic box/plastic outlet cover), this method will make it difficult to detect what openings of the outlet are hot. What we found works well is to approach each opening from the side.  To say it another way, if checking the outlet slot on the left side, approach the outlet from the left.  If checking the ground opening, approach the outlet from below. This is assuming the outlet is installed with the ground opening downward; if you approach the outlet from below you should be able to tell if the ground is hot.

If ground opening is toward the top, you can approach from above. We think if you try this, you will find that it is a much more accurate way to determine what parts of the outlet are hot. Remember that your body is part of the functionality of the device and completes the circuit.  If you move your finger toward the tip of the non-contact voltage detector (where the antenna is), you will find that this effects (reduces) the sensitivity.  Although not an official method of using the device, you may find this tip useful to know in differentiating a hot line, particularly when the field is large or there are several lines in close proximity.

Adjusted

Obviously, do not put your finger near the tip when checking an exposed conductor. It would also be appropriate to wear the proper protective gear for safety.Gloves

GDT-292A, 293A, 294A, & 295A Fuse Replacement

GDT-292A assembled showing 3 red insulatorsInstructions on how to replace the fuse inside the GDT-292A. These instructions will also work for the other versions of the meter: GDT-293A, 294A, & 295A. This is an older multimeter that we no longer manufacture, but we would still like to make people aware of how to replace the fuses safely without altering the multimeter in a way that could make using it dangerous. Luckily for us the customer was able to supply these pictures for others who may need help in the future.

To replace the fuse(s) open the case as previously mentioned in the manual, and remove the Printed Circuit Board (PCB) from the front cover by ONLY removing the four larger screws that are located toward the top of the meter and that are spaced to form a rectangle. The PCB and cover will now be able to separate easily.

 

5, What should be seen after PCB removal

DO NOT LOOSEN OR REMOVE THE FOUR SMALLER SCREWS THAT ARE LOCATED TOWARD THE MIDDLE/BOTTOM OF THE METER AND ARE SPACED 4 CM (approximately 1 1/2 inches) APART AND FORM A SQUARE.

 

 

 

 

 

 

 

 

 

(These four smaller screws marked in yellow in the above image hold the rotary switch in place.) DO NOT REMOVE THEM!

6, Fuses sitting on top of holders'For protection against fire or injury the fuse(s) should be removed without causing damage to nearby components and should only be replaced with fuse(s) of the same specified voltage and current ratings as specified in this Operator’s Manual.

7, Fuses removed for testingRefer to the two photos above. One black and three red rubber insulators surround the four jacks that the leads can plug into. The insulators are held in place against the PCB by the front cover. Upon dis-assembly one or more of the colored insulators may get stuck in the cover (in this dis-assembly one red and one black insulator were stuck to the cover). For ease of re-assembly, the stuck insulators can easily be pressed out of the cover and put into place on the PCB (wide end toward the PCB) as the two red ones in these photos are. Just remember, the BLACK rubber insulator goes on the post of the PCB labeled “COM” (of course). These insulators ensure a snug fit of the leads without using split-tip leads that lose their tension over time.

HGT6120 – AFCI Circuit Breakers

There were concerns that the HGT6120 would not function correctly on an AFCI Circuit Breaker, causing the breaker to trip as soon as you plugged our tester in. AFCI translates to Arc-Fault-Circuit-Interrupt and on many new models comes equipped with a self-test. We went ahead and started testing to see what the issue was while using the HGT6120 and all of our other GFCI circuit testers on AFCI circuits. During testing we used many different AFCI circuit breakers from multiple vendors. We were not able to find any issues while testing and we didn’t have any problems using any of our circuit testers on the new AFCI circuit breakers.

There is one other theory as to why this is happening on AFCI circuit breakers. It could be that the circuit breakers being tested are older and more prone to tripping. Circuit breakers are like most switches and over time they wear down. If this is the case and they aren’t functioning properly, they may need to be inspected and replaced. In any case, a licensed electrician should be involved to determine the root cause of the problem.

 

WiFi Inspection Camera (WIC-100) Troubleshooting

If your phone is not displaying the video feed you can try these steps to resolve the issue:

1 – You’ll want to first shut down the application.

2 – Turn the WiFi Camera off and then back on. (Make sure that you feel the click and that the light goes all the way off)

3 – Check to make sure that your device has established a connection with the WiFi Camera.

4 – Re-open the application.

If the above steps failed to resolve the issue: Reset the WiFi Camera by holding the reset button down 5 seconds. Perform this action while the camera is turned on. The reset button can be found next to the power wheel. See below picture.

WiFi Inspection Camera (WIC-100) Battery Install

The battery door is located on the bottom of the handle. Using your thumb; push the door away from the housing towards the rubber grip. Once the battery door has been removed the battery cartridge will slide out. Install four double AA batteries into the cartridge and replace it back into the handle and install the door.
