GS38 Compliant voltage indicator recomendations.

[Pete999]

I have a T110. The RCD trip function has never worked. Now neither does the continuity or self test functions. There are recognised problems with the T series from Fluke. Steer clear.

The thing I don't understand, is why would anyone want to buy a voltage indicator that does all you need one for is to measure if there is a voltage present or not, RCD function, why? when you have a function on your MFT for that purpose, continuity, why when your low resistance ohm meter does that as well, just saying, awaiting a backlash from members, who revel in these testers.

Absolutely. . one of these will comply. i have one myself.

Hey Pete! Here's my cheap, cheerful rugged, British made voltage indicator. Batteries neither included nor required. It does what it says. Detects voltage.

RCD function... in a board that isn't marked up, you can check for voltage, trip the board, check again and then go and lock off... all without moving It's a limited test function in that all it does is attempts to trip and RCD with a 30mA current. This function can also serve you when suddenly you get a voltage present you weren't expecting... say 50v neutral-earth.... you can apply the low impedance mode... if the voltage disappears it's a good chance it's a phantom voltage from inductive/capacitive coupling.

Continuity is useful for buzzing out circuits and testing fuses, bulbs, operation of switches etc. without the need to break out the big guns.

The other functions are useful as well, like voltage indication and phase rotation.

It's no replacement for an MFT (or separate dedicated instruments) but it can be a useful piece of kit for fault finding.

Bugger Tel were on earth did you get that jobby ? I still have my intrinsically safe one, and no it aint for sale.

Thanks for all the responses so far, as expected a wide range of opinions, suggestions and personal experiences. Some of which are contradictory too.

So just to confirm do the Fluke indicators trip RCD's un-intentionally when you don't want it to trip or do you have to press a button for the RCD trip function to operate? Also are the Flukes GS38 compliant out of the box or do they require caps for probe tips to be purchased separately to make them compliant? The websites I have looked at dont seem to mention GS38 compliance for the Flukes wheres as they do for others hence why I ask this.

Finally anyone else have any problems with the Fluke as Andy78 has mentioned?

I didn't get it for the RCD function at all, just noticed it never worked. I personally don't see the point either.
Continuity on my voltage indicator can be very helpful when quickly tracing circuits or fault finding. I don't use it for continuity readings, just a beep to confirm continuity.

MFT comes out for all proper testing of course

I have a Fluke T150... it is GS38 compliant as it comes with probe shrouds that can be removed (like the Martindale).

So just to confirm do the Fluke indicators trip RCD's un-intentionally when you don't want it to trip or do you have to press a button for the RCD trip function to operate?

It can trip RCDs, when I want it to... by probing between line and earth and pressing a button on each probe that drops it's impedance such that around 30mA will flow through it.

I have never had it trip an RCD unintentionally. If you look at the specification sheet for it under normal conditions (i.e. without the trip buttons pressed) it's impedance is way too high for a current of sufficient magnitude to flow through it.

As for the reliability, Andy isn't the first person I know of who has had an issue with it, but my own personal experience of it is entirely positive and I would buy another if mine were to expire.

Thanks for all the res-ponders

The main purpose of this for me as mentioned in original post is for safe isolation. Continuity confirmation will be nice to trace out circuits quickly / simple fault finding as Andy mentions.

Given the above, I don't know if I can justify the cost of the T150 fluke though.

Looking for something reliable and durable.
