Most likely they were testing a live circuit. Continuity testers are designed to test UNENERGIZED circuits. The bulbs in these testers are only rated for around 3 volts. If you hook this up to a live circuit in your house, you just put 120 volts through the bulb and that is why it blew out.
No, we do not offer leads for these. The way these are manufactured, you would have to disassemble the entire tester and re-solder new leads on. These testers are not designed to be taken apart.
No we do not. Due to the fact these are kind of awkward/specialty bulbs, if you can find them, most times the store carrying them is charging almost the cost of a new tester if not more. The continuity testers are pretty much designed as throw away items. For the voltage probes, most times these are soldered directly to the circuit board and are not to be replaced.
These testers were designed for quick basic testing to determine if there is voltage at an outlet or on a line. They are not designed to pin-point which line is the hot and which is neutral. For that you would want to use the VD6505 because they have an adjustment for the sensitivity to dial it down and give more accurate readings.
No, we do not have replacement lenses or decals for the outlet testers. Any of the testers that have lenses that would fall out have been obsolete for about 2 years.
No. Due to the changes in the design of the housing, we do not recommend using the new accessory kit with the older style breaker finder kits. The CS61200 transmitter that plugs into the accessory kit has a different molding shape and it clicks into the accessory adaptor. The older kits have a flat front to them that will not fully sit in the accessory kit. This will leave parts of the metal prongs for the transmitter exposed and could potentially cause a shock hazard for the user. The accessory kit for the older breaker finder kits has been discontinued with no replacement.
Depending on how many breaks/splices are in the wire, people have been able to trace wires across extremely large warehouses and stores. The more splices there are in the wire being traced, the weaker the signal is going to get down the line. Rule of thumb is for every spice in the wire, the signal is getting cut in half.
Depends on the wire, how deep it is buried, and the soil. Most wire that is going to be buried underground is going to have a thick jacket and possibly shielded. Shielded wire is going to block out the signal leaking out of the wire to be traced. Normally we answer this as no.
This depends on how far behind the sheetrock the wire is, the type of wire it is, if it is in conduit or not, how thick the sheetrock is, and how new the batteries are in the testers. As the batteries in the tester weaken, the signal being sent is weaker and the transmitter has a harder time picking up the signal. If the sheetrock (drywall) is extremely thick or even doubled up, that is going to affect the receiver’s ability to pick up the signal. If they are trying to trace BX wire (wire in an armored sheathing) or if it is in conduit, it will not be able to detect the wire. These metal encasements will block out the signal being sent and the transmitter will not pick anything up.
Currently we do not carry any of the replacement temperature probes. Best place to find replacement probes is from www.omega.com .
