Recently we had a customer request information and instructions 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.
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!
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.
Refer 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.
There were many complaints 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 of course did not find any issues or have any problems using our circuit testers on any of 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.
The grease used to build and service the B2000 is Sta-Lube’s Extreme Pressure (Moly-Graph), multi-purpose grease. You can use this grease or any other multi-purpose grease to service the B2000.
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.
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.
