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.

Will this meter read amps on a thicker insulated wire, or even an extension cord?

Asked by: Aa_Ron_Rufus
The Fluke T5-600 Electrical Tester can read on thicker insulated wire but will not work on an extension cord, as it has multiple conductors and you have to only measure one conductor.

Will this meter pick up ghost voltages?

Asked by: Jim P
The Fluke T5-600 Electrical Tester should not give you ghost voltages as it has a low input impedance.

Is there a test probe adapter for an alligator clip?

Asked by: Jimgo
The Fluke AC285 SureGrip&trade; Alligator Clips will plug in to the Fluke T5-600 Electrical Tester.

Rated 5 out of 5 by from T5-600 sweet Volt, ohms are good, love the plug outlit meter leads thats 5 star itself. Haven't tried amps in a high amp envioment. BUT AS USUAL FLUKE COMES THROUGH.

Rated 3 out of 5 by from Unclear if it can measure DC Current. I anm thinking in buying one to replace my , but the advertising is Unclear if it can measure DC Current, and its range limit. Can the lighted display keep on? Does it has a “hold” option. Can the probes be detached? It seems to be permanently connected. What is the IP protection ?

Rated 5 out of 5 by from Excellent voltmeter got right stuff This little meter shines in comparison to other meters for the $$. It's 3rd party tested with credentials, it's Fluke which means it rugged and accurate. I teach electrical safety so the T5-600 and T5-1000 are my go to so as to give my apprentices and techs the safest and best meter at a price point and size affordable and convenient

Rated 5 out of 5 by from Have used this brand for years and is reliable. Maintenance is glad to have it in their inventory.

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 $.
