What is the difference between this one-probed tester and the testers that have two probes (red and black)? I am confused what each type is used for.

This tester senses A/C voltage without requiring metal-to-metal contact with the wires or terminals you are testing. It can sense A/C voltage through the wire insulation. The two probe tester you are describing needs the metal tipped probes make metal-to-metal contact with the "hot" and "neutral" or "hot and "ground" of the circuit you are testing. Also note, this tester only works with A/C systems, such as house wiring etc. and does not work with battery or automobile type systems.

I can only guess that the one with the red and black probes would be for testing dc current.red for positive polarity and black for the negative terminal.the other tester with no probes is for ac circuite. hope this helps.

Not that I am aware of , shortly after I bought my reason for buying it became obvious without using this,there is a lot of videos out on using one, I can tell you the broken wire tester works great I have used that. As for the power probe itself, the maker and other people will warn you to be careful in using it because you can send 12 volt current to components that will wind up burned out,that said I am sure there are applications where this tool will fill the bill.

The question is confusing. It is not clear what you are trying to do here. If you can hang the meter with a magnetic strap you would have two hands free to use the probes. You can also buy an assortment of test probe clips so you can clip one probe to a neutral or ground and then still have two hands free the hold the meter and use the red test probe for measurement.

This one cannot be used without the external probe. The probe has the sensor...But you can buy the other one with the built in sensor in the back of the unit. Personally I like the probe better..

The tester works with any USB device. You connect the tester to the USB-A port on any device, like a computer, printer or charger (car/power) and then connect the cable that charges your device to this.You then connect your USB cable with the familiar A-end to the tester and the other end USB-B (printer) mini, micro (phones and cameras), lighting (newer iPhone and iPad), 30-pin (older iPhone, iPad or iPod) or proprietary to your device.

You have to use compact plus strips for a compact plus tester. You also have to use the compact plus testing solution for a compact plus tester.

you have to find the duplicate unit, i think sears sells, then use their on line manualI hated it at first then i realized the logic, one button controls both temp sides and to calibrate use stired ice water with both probes in the water, stir fast with lot of ice and set at 32 f

I think there is no different, it is just ur prefer and i didn't know they make blue displays in redline detector. The redline detector is always red.

12 volt (red and black). red goes to any always on circuit. amperage is so low it doesn't affect any circuit. black goes to rv ground although i went all the way back to the battery each time. i use three of the units and they make life much easier. be sure polarity is correct or the readout will be backwards. yes, i got one wrong the first time i tried.

It doesn't need a probe. The buzzer and light are much more sensitive then on most other voltage sensors; you don't need to probe into a receptacle to know whether there's power or not. Just hold it in the vicinity (about 1/2" from the receptacle.) Probes break off. This sensor lasts.

It can not test any battery well. There are other testers better then this. There is an inexpensive tester out there. I do not have the model number. It is black with a red slide to make contact with the terminals of the battery. It works great.

I tried other non contact testers and they tend to give you inaccurate warning. e.g. if you have a neutral carrying current because there is incorrect splicing somewhere else, it will give you a wrong signal unless you separate then far apart to test them individually. This one is pretty accurate.

I bought this for my husband and he said he has no experience with the Test-Um's Resi-Tester. Sorry we could not help.

I do not know for sure, but some probes I have owned work in other units. If you do purchase this unit, you can test if it works by taking a glass and filling it with ice cubes to the top. Then fill it with water so that the ice cubes are completely submerged and stick the probe into the middle of the cup with the ice. It should read to 32F or 0C within 3 minutes. If it does not, then it sadly will not work with that particular unit.

To add to Phillip's statement. This testor is designed to test cables. As you can see, the testor consists of a sending unit (the larger device) and a receive (the smaller device). Each device has two ports in which to insert one of the following, either an RJ11 (telephone / MOD6 plugs) or an RJ45 (data / MOD8 plugs). If you were testing a data or telephone cable, it would have a plug at each end, either an RJ11 or an RJ45. If you were testing a patch cable, you would insert one end in the sending unit and the other end in the receiver. If you were testing a cable with a jack installed at one end, and either an RJ11 / RJ45 plug at the other, then you would need a short patch cable to connect one of the devices to the jack end. If you were testing a patch panel to a jack, then you would need two patch cables to test the cable. The unit does not come with patch cables. I hope this answers your question.

I purchased a BAT-250, it is red and the meter display is located at the top not side of the tester. Mine works great and would highly recommend it. As J.Qualey mentioned with the BAT-250 it has a groove to better hold and keep the contact points of the batteries in line for testing.

No, it only works on unpowered cables. You put one part of the tester on one end of the cable and the other part of the tester on the other. Each end can be in different rooms.
