Q:Wmcksmith, how does it work without batteries if you are testing a receptacle that typically would not be outputting any power if it is being troubleshooted? I think you answered "no" too quickly and should correct it not to mislead anyone.

Answer This Question

A:  This tester is not like the ones with 3 lights that you have to look on the chart to decipher the state of the wiring. This unit has an LCD display that tells you the state of the wiring in writting word. It requires batteries to operate.

    A:  If it doesn’t light up the plug isn’t connected to power. 

    by|Mar 6, 2023

      A:  Batteries are required and included (2x AAA)

            A:  yes batteries are required This is a quality unit and works well My retired electrician was impressed with this outlet tester If you forget to turn it off it will self turn off to preserve the battery life Nice addition to your tool bag !

                A:  Requires batteries  But Not complicated works very well very handy and my retired. Electrician friend was impressed by it. If you forget to turn off the batteries, it will shut itself off, so I wouldn’t let the batteries be a big concern.

                        Such a solid and feature rich multimeter
                        This thing is rock solid. Makes fluke meters feel like toys. Definitely has a noticable rigidity and quality feel that most clamp meters lack. Flukes and ideal meter feel cheap. They measure fine and all but don't have the robust build that this does. Combine the build quality with the accuracy and rich feature set and you can't beat Klein for the money either.

                        This is a game changer
                        I bought this a month ago. I use this on my side job work and I also use it at work. I just like how it helps make troubleshoot stuff.

                          Great meter with lots of features for the price
                          After reading the reviews from others and looking at the price for features this meter has I went with the Klein CL800 for my A/C and electrical jobs. So far it works great and the accuracy is fine for field work.

                          Ok meter, hard to read screen and no tone with NCV
                          Good feature set and feels good in the hand. I just hate how faded the screen gets at an angle or when I turn on the backlight. The last thing I want to do is have to stick my head in a box to view the screen or twist some wire. Also the NCV has no tone alarm, so strange. Normally I'm a big fan of Klein but I'm a pass on this tool. Fluke or Ideal clamp meters for me.

                            quick & easy. [HD needs to increase review limit]
                            voltage reading is my reason for getting this. a 2-3' extension makes perfect .. i added outlets & switches years ago & getting little shocks ,, but all is good finally with this tool . i suspect it was static carpet shocks. HD double write limit

                              This is a great tester with which you can test and diagnose variety of problems such as improper wiring, faulty grounds, timing for tripping of GFCI receptables and most importantly - voltage fluctuations. This is particularly helpful when you need to diagnose and service generators, flickering lights due to deteriorating connections on your main panel and so on. For the price, it is a must have in every service van and toolbelt and a very good addition to a home's repair kit.

                              Awesome tester
                              This is the best gfci tester I’ve seen. You can check voltages on a gfci receptacle or a regular one. It also tells you how fast the gfci trips

                                Good for voltage, amperage, etc., but not for temperature.
                                Overall, the clamp meter is of good quality with acceptable results, when comparing it to the Klein MM700 multimeter. The discrepancy comes with using the thermocouple on the clamp meter. There was a sizable, erroneous difference when measuring ambient air temperature in a dwelling. My MM700 read 66.0F while the CL800 read 152.3. Upon switching my banana adapter and thermocouple from the MM700 to the CL800, the ambient temperature was only 0.7 degrees different than my multimeter. I contacted Klein Tools, informing them that I only wanted a new thermocouple and adapter. Unfortunately, they wanted the entire clamp meter with accessories back. Klein Tools, being a solid company, sent me a whole new CL800 clamp meter within 4 days. While there is some difference in temperature readings with the new CL800, I will use it more for voltage/amperage readings. As for the GFCI tester, I love it!
