Product overview: Fluke T5-600 Electrical Tester

The T5-600 Electrical Tester is a versatile troubleshooting tool you can carry to every job site. Use it to check voltage, continuity, and current, all with one compact, rugged tool. Just select volts, ohms, or current and the tester does the rest. For higher voltage applications check out the Fluke T5-1000.

This meter is perfect for my use as I do HVAC and Electrical work, and this will give me what I need for troubleshooting and performance of equipment.” - Paul

Measure current up to 100 A without breaking the circuit with OpenJaw™ design

The trendsetting OpenJaw™ design allows for fast and easy current measurement, safely and without metallic contact to a live conductor. The integrated protection circuit allows it to stay connected to a voltage source longer than a solenoid tester would be able to. The T5-600 is also designed to:

  • Withstand a 10 ft. (3 m) drop
  • Conserve battery life with auto-off mode
  • Fit in one hand with handy probe storage in the back of the holster
  • Accept Fluke accessory test clips with the test leads

Meter automatically selects AC or DC voltage for tests up to 600 V

Voltage tests are faster and easier than ever before. Just turn the knob to voltage (V) and place your leads on the test points. The T5-600 auto-selects either AC or DC voltage, depending on what is detected. This meter is suitable for both residential or commercial applications and is designed to keep you safe with a CAT III 600 V rating.

Reviews: Fluke T5-600 Electrical Tester

Rated 2 out of 5 by from Only checks AC amperage This only checks AC amperage and not DC. It doesn’t even mention that in the description. I wasted my $$ on this one.

Rated 5 out of 5 by from Money well spent This is one of those tools that not only can I not live with out, but truly feel like I got my monies worth. Upon my retirement as a vocational instructor I had to buy my own meter after years of having one supplied to me. After years of purchasing this meter for my students and seeing the abuse that a high school student can put them thru there was no question in my mind what I was going to buy. I still have my original "Wiggy" that I got as an apprentice 40 years ago. I have every expectation that my Fluke T5-600 will be around just as long.

Rated 5 out of 5 by from A nearly perfect electrical test The t5 600 works as intended, it can check ac/dc voltages, ac amps and ohms/continuity. Honestly this tester is nearly perfect and I can't take off points for options the product does not offer to begin with but I do think that adding a backlight to the t5 line would add a lot of value to an already great tester. I was debating going with a t6 just for the backlight on the screen alone but the extra cost and field sense feature did not seem worth the $.

Rated 5 out of 5 by from Nice for reading Amps T5-600 is Great. Question will it work AC Line Splitter example Tekpower M920 AC Line Splitter, does Fluke have a unit that will work with the T5-600

Rated 4 out of 5 by from great limited range tester for everyday functions I brought mine in 2006 so its about 13 yrs old, and its seen and been through it all and theres been no real issues! My only complaint (and id be glad to be corrected) is that you cant mesure amps between A+N with the test probes to see what an outlet cct may be drawing. But for the price and ease of use, and the probe holder on the meter (which is a great function imo) its a good little all rounder!

Rated 5 out of 5 by from Safety first I bought this my first year as an apprentice and now in my 3rd year still great.

Rated 4 out of 5 by from Great value. A few shortcomings. This is my second t5-600. Love the light weight, multiple features (Amp clamp, vom). Higher resistance reading would be a plus, but I realize that Fluke doesn't want to eat into the market for it's other meters. My large Fluke meter has a lighted display. That would be awesome on the T5. Be warned: My old meter did not have detachable leads. I don't feel that feature is needed with this type of meter. If you put one of your probes in the socket in the back so you can test while holding the meter, it is very easy to get the probes in there so deep that once you try to remove them, they come unplugged from the leads. Mine would come unplugged every time. I called Fluke tech support and the tech got a T5 and was quickly able to recreate the problem. His solution: Try not to wedge them in too tight. :-( My solution: (super glue doesn't work) If you wrap a piece of electrical tape around plug where the lead connects, it makes it difficult to attach the probe, but it will stop coming apart each time you are finished using the meter. Come on Fluke, you make world class products. You can make this meter better.
