Measure voltage … without test leads

We know working in electrical boxes jammed with wires can be challenging when you’re trying to find a safe metallic contact point. Now, with Fluke’s T6-600 or T6-1000 with integrated FieldSense technology, you can quickly and easily take measurements by sliding the open fork over a conductor to see the voltage level without the need for test leads.*

Why use the T6 Electrical Tester?

Electricians often work in boxes jammed with wires, where finding a safe metallic contact point can be a challenge. With the T6-600 or T6-1000 you take measurements by sliding a single wire into the open fork.

How FieldSense Works

FieldSense technology is truly a breakthrough in how voltage is measured. While other open fork testers detect a magnetic field to show ac current, FieldSense technology detects an electrical field. This field interacts with a reference signal created by the T6 tester, creating a voltage value on the tester’s display.

Who needs a T6 tester?

Commercial and light industrial electricians can use T6 Electrical Testers for most everyday measurements. These devices easily fit in your pocket, making them easy to access on the front-line for electricians of all industries.

* Voltage measurement requires capacitive path to ground, provided through user in most applications. Ground connection via test lead may be required in some situations.

Measure voltage up to 1000 V ac through the open fork, without test lead contact to live voltage.+ Without opening covers or removing wire nuts. On wires up to AWG 4/0 (120 mm2), carrying as much as 200 A. It will change your job. Safer. Faster. Easier.

  • additional ground contact is required for the application

FieldSense measurement looks like this when properly grounded:

Correct Display
  • Display color turns green
  • Display shows a valid measurement >16 V rather than dashes or 0.0
  • shows for measurement ≥30 V
* Voltage measurement requires capacitive path to ground, provided through user in most applications. Ground connection via test lead may be required in some situations.

Rated 5 out of 5 by from Amazing Meter Hands down amazing. It's new technology meaning it's different. Once you figure out how to use it properly it's an amazing troubleshooting meter. I've had absolutely no problems with accuracy after I figured out how to use it correctly. I would love to see phase rotation on the next go around. I could care less that it doesn't read microfareds and probably not the best for residential. I use it all the time in commercial and industrial!! Revolutionary!!

Rated 5 out of 5 by from Tight little package . Bought one in Jan, used it lots already . Since I sometimes work on fire and security systems , I like the more capable Ohm ranges . Feild sence works well , and is handy to have . It’s a rugged compact instrument , carrys well on the belt . A lot easier than digging out my 87 ! If I could change anything , I would add a MegOhm range . Then I could leave the 87 in the toolbag .

Rated 4 out of 5 by from Nice all around meter I saw this meter a while back and couldn’t wait for its release. I bought it and right away there a some features that are really nice. Having the back light is a major plus. The field sense takes a few uses to get used to how it works. But it is really nice to see amperage and voltage at the same time while troubleshooting. All around another good fluke meter. The only complaint is the voltage is not super accurate. It’s within 10%.

Rated 2 out of 5 by from thinking about buying I'm on the verge of buying but the biggest issue I'm afraid of is what happens if the leads get damaged? on other meters, I purchase a new set of leads once a year. just to be safe.

Rated 1 out of 5 by from Highly Disappointed. When I ordered this meter in October, I was told an 8-10 week lead time. 4 months later, I finally receive my meter, and not only does the TPAK hanger not work with it, it will not read a proper ground, even when I connect the lead to a monitored ground connection. I love the idea, but this meter leaves a lot to be desired.

Rated 4 out of 5 by from Great Meter! Well Designed!! I got this t6-1000 meter recently and have been very satisfied. The field sense feature works great with the ground contact button on the back! I think it is important to know when to use the contact button or the black probe. I believe the T6-1000 Will perform well and give accurate readings for anyone that takes the time to learn how to use it properly. The one thing I am very disappointed/confused about is how the world are you suppose to use the TPAK magnet kit with this. I have a few meters with TPAK and I don't see how to put on this meter? Is there a new series of TPAK or???? I hope I don't have to spend more $$$ to get a different TPAK! Over all very useful unit.

Rated 1 out of 5 by from T6-1000 not a good choice I bought this meter with the intentions of using it in a healthcare environment to make trouble shooting easier and safer. Unfortunately this meter does NOT fit the bill AT ALL. First of all it requires you to touch a ground pad on the meter or use the ground(black lead) to establish a ground reference for the Field Sense to even operate and with the ground pad the voltage readings swing wildly and never settle out. Using the ground lead the reading settle out somewhat but still remain way out of range compared to two other meters I used to check against the T6-1000. Also an alligator clip is shown in the photos and naturally is not included and neither is a simple case or hanger. Im sorry but for this price point it should be a given that these things are a standard now. Don't worry there will be a Asian version for half the price that works better with all of the accessories within a year. I guess we lose again america. I will returning this unit a soon as possible

Rated 1 out of 5 by from Not working Bought this tester today thought I would give it a try. Will be taking it back tomorrow, after turning it on it just flashes ERR (error) and CAL (calibrate) I assume, Have had t5 for 10 years without one single issue.

Rated 2 out of 5 by from Fieldsense is not quite ready for primetime yet! I ordered this new technology skeptically shortly after product announcement. And it's about what I expected, and have heard from others while waiting for it to arrive. The FieldSense for voltage is pretty unreliable without a connection from the black lead to a good ground. Using the only the backside ground button/pad, I've gotten readings anywhere from 0 volts to 347 volts (how coincidental is that??) from a single 120v conductor while standing on concrete in regular work boots. I can't even trust it to determine if ANY voltage is present, because it has indicated -0- volts on energized conductors, while indicating that it had an "acceptable" earth ground. Same issue exists even if I am touching a good earth ground point that works for the single-lead method; so grounding yourself doesn't appear to make it any more reliable, even if the screen shows you have a "good" earth ground connection. And yes, I had the both leads docked in the storage slots (this is important) while attempting the readings. Using FieldSense with the black/ground lead on a good ground seems to be reliable and accurate, so I'll give that method a thumbs up. Just wish it worked truly "leads-free". The other features are worth the price though, love the backlit screen! Maybe this concept will get better in a few generations. So if you're thinking about a purchase, maybe hold off until the technology improves, accept FieldsSense as a "novelty" feature in lead-free mode, or go with the seemingly bulletproof T5.
