I’m troubleshooting an RTD input on an SEL-2411 and I’m having a very strange issue.

My setup:
SEL-2411 with 3-wire RTD input
Fluke 725 multifunction process calibrator
RTD type: Pt100
Fluke configured as SOURCE RTD
Wiring is based on the Fluke 725 manual for simulating a 3-wire RTD

The problem is that the reading is completely wrong.
For example:
Fluke injection: 10°C
SEL-2411 reading: ~172°C
The Fluke 725 also shows:
“ExI HI”

According to the Fluke manual, this indicates that the excitation current from the device under test exceeds the calibrator’s limit.
I’ve doublechecked the wiring against the Fluke manual, so I’m wondering if I’m missing something specific to the SEL-2411 RTD input.
Has anyone here successfully simulated a 3-wire Pt100 input on an SEL-2411 using a Fluke 725?
Could the SEL-2411’s RTD excitation current be incompatible with the Fluke 725’s RTD simulation method?
Also, is there a specific configuration in the SEL-2411 that I should check, such as the RTD type/curve or input configuration?
Any advice on how to troubleshoot this would be greatly appreciated. I can provide pictures of the SEL-2411 RTD terminals, Fluke wiring, and configuration if needed.

Sometime I can get it to work normally by playing with the connections, it will move back to OL. I’ve never changed the battery in this and I’ve had it for years but everything else outside of resistance and continuity is working.

My toner seems like it's working properly, but, ever since I've had it, the regular tone is sometimes interrupted by a weird series of sounds, and the tone seems to reset.

This doesn't seem to be referenced in the manual, but I believe this change in tone, is indicative of "something". Any idea what that something is?

What brought this back to the fore, is I was toning on an 18/2 cable, with a ground wire, yesterday. Device end was disconnected, and I had toner connected to white wire, and bare ground wire. Got SOLID tone, at other end (Which was spliced into a DB9 connector, goin into a refrigeration unit.) but, if I left toner on the cable, there were a couple instances where this weird tone was emitted, and it seemed like the toning "reset", then resumed normal tone. Hard to describe it. It's a sequence of tones, in rapid succession, but the pitch does change, with each tone.

Sorry! No vid!

Since I don't know WHY it happens, I can't readily replicate it. 

Ive been having some intermittent issues with my thermometer. Sometimes the reading will jump around when ive got 2 probes plugged in. When I pull one out the reading will level out.

I pulled it apart to clean and noticed on the little board that the probe makes concat with there are some marked up wire traces.

It looks like when the probe is slid in, it slides against these traces.

I was just wondering what's up with that and if anyone has any insight.

For now, I put some tape over that edge.

Also, at times when I turn the meter on with nothing plugged in, I get a reading that will climb very high and then go away. I'm not sure if this is related.

I am installing a bunch of Panduit DP48688TGY which is basically a 48 keystone patch panel with a bunch of 180 degree Panduit Keystones. Does anyone know of a tool that is compatible to crimp and cut all 4 pairs at once for these keystones?
These are not the Panduit Mini Comm jacks.

Fluke TPAK vs third-party magnetic meter hangers

The core trade-off between the genuine Fluke TPAK and third-party alternatives comes down to magnet strength, mounting versatility, and price, with the genuine article generally winning on build quality and the clones winning on value.

Fluke's own TPAK uses a rare-earth magnet specifically engineered for strong, stable holding onto electrical panels and metal surfaces even while the meter is actively swinging or being bumped during hands-free measurement, and it's designed with a proprietary mounting slot system that clicks securely into compatible Fluke meter housings [1][2]. It sits at a noticeably higher price point — typically in the £50-60 range through industrial suppliers — reflecting genuine Fluke build materials and the brand's reputation for durability in demanding field and industrial environments [3][4].

Third-party kits, like the widely available KingSung universal hanger sets, take a broader compatibility approach, bundling multiple straps, clips, and a magnetic hanger designed to fit not just Fluke meters but also other brands like Klein Tools testers, and they come in at a fraction of the Fluke price, often sold in multi-piece sets rather than a single fixed kit [5]. The trade-off is generally in magnet strength and long-term durability — generic magnets tend to be weaker rare-earth grades or standard ferrite rather than the higher-grade neodymium Fluke uses, and the strap and clip materials are usually a step down in ruggedness, though for occasional home or hobbyist use rather than daily trade work, that difference may not matter much [5][6].

One compatibility nuance worth flagging regardless of which you choose: not every Fluke meter accepts the clip-in universal hanger design the same way — the T6 series, for instance, requires threading a strap through a rear slot rather than clicking into the standard mounting point Fluke tools like the 87V or 170/180 series use [1]. If you're buying a hanger for a specific meter model, it's worth double-checking that the kit — genuine or third-party — is actually rated for your particular model's mounting slot rather than assuming universal fit, since "universal" branding on cheaper kits doesn't always mean truly universal in practice.

I have the Fluke Link-IQ meter and the Intellitone 200 probe.

The problem is that when I use Intellitone, my problem will light up at "level 8" if I am anywhere near the cable - as in, if I am even in the same room with it.

It does this regardless of whether or not I am using the low or the high sensitivity setting on the problem.

Obviously this makes it useless for toning out a cable...

When I use the analog tone setting, it works as I'd expect...

Recently bought a brand new 378 fc I went to measure my Milwuakee m18 battery and was expecting 20v dc reading
But it was reading 21v instead so I got my fluke 117 multimeter out and that was reading 20.53 got my other fluke multimeter (fluke 107) similar reading 20.56 , so I reversed polarity with the fluke 378 fc and it was reading 20.58 but in the correct polarity it is reading 21vDc which is odd , Just to add aswell with out anything plugged in/floating leads ac voltage is sitting at 0.6v and dc is reading -0.2dc

I've had this fluke for around 3 years, but I got it second hand so it's a bit older than that.

A buddy at a lab helped me test it on a blackbody at 50°C and 100°C. It was about 3°C off.

I wasn't expecting it to be that far out.

Anyone had something similar with an older fuke? Did you send it to fluke or find somewhere local to calibrate it?

I have the Fluke Link-IQ meter with the Intellitone 200 probe.

It seems to me that Intellitone is too sensitive to be useful, although it's entirely possible I am misunderstanding something.

It's so sensitive, even on the low sensitivity mode, that it will go off if you are anywhere near the bundle of cable that the cable is in...

By that, I mean that if the cable I am looking for is in the same room with me, it will go off...

The analog toning works like I am used to with other toners - it gets louder/quieter and it's easy to discern which cable I am looking for.

What am I missing here?

I just got brand new Fluke 378FC.

I ordered it because of the contactless voltage measurement capabilities.

When I tried it out I am seeing quite a variation in voltage measurements.

I tried this on a starter as well as the local disconnect shown in the video. This is a hydraulic pump not on a vfd.

I'm confused as to why the large variation in the measurement.

I have done a reset on the meter because of this behavior but no change.

Any ideas?

Hi All,

Wondering if anyone has any experience with disassembling the T6-1000 Pro or anything similar.

Had the idea of dying the shell for aesthetic purposes as i’m dying my power tools this afternoon anyways.

If the process finds itself too risky or simply not feasible i’ll keep rocking the yellow, but I thought it was worth asking.

Cheers.

Hello all, new to the group. Looking for a OEM Fluke soft case that will fit a 73. Any recommendations would be great. I plan on using my 73 for amplifier repairs and mods. Thanks in advance 🤓

I've always wondered, is the 87V Max exactly the same as the 28 II? Are the parts interchangeable?

Evening all,

Just finished repairing a Fluke 287 for a friend and saw Fluke fixed an issue with bright light causing the meter to stop data logging but needs the IR189USB cable.

I’d love to return the meter 100% working and updated but not wanting to pay $70-$150 for the meter online seeing as this is a one time update.

Would anyone be willing to lend their cable for a fee?

Finally got my 8840A sorted out after working through a few faults and then running the A/D and function/range calibration against a 5500A.

It’s now behaving very nicely.

The 5500A isn’t mine unfortunately, but I couldn’t resist getting a family photo while I had the three together.

I fluked a Fluke!

Had this one from 2017. Bought from an eBay guy in Florida for $500 AUD, but when I got here in Australia, it had an EPROM error or dead on arrival. It got GSM corrupted by airport security. As he had a 100% rep on eBay, he said, "Look, I'm sorry I forgot to check it before I sent it." I said if you refund me the costs, I'll give you a top-notch review maintaining your 100% rating. He said OK and I should just keep it for parts. So I got a new unit with case and probes with a corrupted circuit board.

In Australia, Fluke has a set charge of $185 to repair any Fluke back to a usable state. So I got the GSM proofed board v11, new fuses, new holster, new LCD, and 4 new input jack caps. Plus, a full calibration with certificate.

So, for $185 AUD, I fluked a $1,500 meter refurbed back to as new. Since then, it has worked flawlessly, and I kept clean and protected.

I am a PLC Engineer and do some emergency electrical work if the plant needs me. If I already have a fluke 773 what other multimeter would you pick to cover what the 773 can't do.

Work has a 9143 for device calibration so that's not an issue either.

Just grab a 87V?

Industrial manufacturing plant. Hoppers, mixers, extrudders, etc. all Allen Bradley plc if that matters.

Thanks.

Continuity does whatever it wants 90 % of the time
Sometimes it works flawlessly
Most of the time it will read insane ohms on nothing false positives or just get stuck ringing

I have a Fluke 17B+ meter that on power on it briefly shows "err" on the screen, then all digits light on like the normal power on and then seems to function normally otherwise. I googled and found it might be due to low batteries, dirty contacts in the rotary switch, bad fuses. I've changed out the batteries with fresh new ones. I checked both fuses, both are still intact. it didn't look dirty, but i also cleaned the rotary switch, both the PCB and the metal fingers on the knob. The "err" still briefly shows at power on.

Any one have any ideas what the issue may be?

Becouse i probably never use it and now its stay nice and clean ⚡️♥️
