I am about to order a set of Fluke TL71 Premium leads for the meter that arrived yesterday. I am not even sure of the resistance or anything else of them I just like them, they suite my hands.
Back on what I wanted to say is that I actually found them on the Fluke website and when I clicked buy now it sent me to a list of retailers one of which is Amazon and they are selling them for $17.84 U.S. dollars. It is Prime sold and shipped by Amazon so that even includes 2 day shipping. Just a heads up for you as their leads can get costly.
That is fairly normal, but even the same DMM can have different electronic/protection inside.
UNI-T do that with Chinese/EU versions, the EU version have lower CAT rating and better protection for the same meter.
Measure 610V within 0.5V, that is impressive (ok, the /- 2 count fixes that, it is only with/-2.5V).
Show off lol.... Honestly I was impressed even with the variances. Depending on how much the meter costs it is a pretty good meter... At least on paper.
It is always possible to ask if you want something clarified.
No, the 189 has more digits. The rated specification will also often also be better for more expensive meter with the same amount of digits, but that do not mean they are more precise, just that they a guaranteed to be more precise (It is not the same).
i.e. A meter rated with 1% /-5 and a meter rated 0.5%/-2 can both show 1.000 volt when you apply 1.000 volt and often will.
Even cheap meters are usual very precise, at least when used indoor at normal indoor temperature.
I have a Fluke 189 and 289. To be honest, I use the 189 most of the time. It’s got an easier to read display contrast wise. It’s been professionally calibrated about a year ago. The 289 was sent back to fluke to have the leaky super capacitor replaced under warranty about 2 years ago. While it was there, they calibrated it and updated the firmware.
My 189 which I’ve owned since 1999 still has a good supercapacitor. Have you checked your 289? It is a known issue with that model. Luckily mine didn’t damage the circuit board because it was just starting to leak. Fluke was really good about taking care of the problem.
It needed to leak a lot more before it could do any damage, but now it is removed. It did not work anyway.
This means it looses the time each time I replaces batteries (I already did that) and that is not really a problem for me. If I need to do some offline logging with time stamps I will have to use another meter.
Hi Ven, how are you buddy? I purchased my Fluke 62 Mini years ago before all the cheap Chinese IR meters came out. I remember it wasn’t cheap. I can only imagine how expensive Fluke thermal imaging meters cost. BTW, I purchased my Fluke meters when I had a decent paying job. Today I’m retired, and very careful how I spend my money. If I already didn’t own them, I’d be looking for much less expensive electronic measuring tools.
Shunt is often used about a resistor when it is used for current measurement.
Burden voltage is the voltage drop in a DMM when it is used for measuring current. If you are measuring current from a 1.2V battery with a 200mV burden voltage (At the actual current) your load will only see 1V, i.e. the DMM will affect the result.
Yes, but if only used for flashlights you can get something cheaper that is just as good. With the Fluke you also pays for safety when using it at mains voltage.
