Fluke 771 Milliamp Process Clamp Meter

I use this for a fast measurement of 4-20 mA circuits. It is easy to use and works well. I wish I had purchased the model that will also generate a 4-20 mA signal but I tried a less expensive alternative with poor results.

Fluke Instruments are still top notch. Came with a nice carry pouch as well.

Product is easy to use and works great. Just clamp on the meter and turn on for 4-20mA signal. Bidirectional so if clamp is backwards still reads just a negative signal instead.

Product was exactly as ordered

Got my order fast and pricing was good.

I use this mA meter all the time. It is a must for checking mA readings without having the disconnect the wires. A very quick, accurate and easy way to verify and calibrate instrumentation in the field. Fluke is a great brand and this meter works well. I highly recommend it.

There aren't too many recent reviews for this, so I thought I would toss in my 2 cents.I already knew this price was out of line, especially since it is made in China, so I picked this up elsewhere brand new for about 1/3rd the cost. If you take one of these apart and compare it to say the Fluke 87V, you will immediately see that this clamp meter is at least double the cost that it should be. There simply is not $600+ worth of components and labor cost here. Honestly, not even $300.Price aside, the 771 is the bottom model of the 771/772/773 series and has really just does the basics. For process work, you do get 0.01mA resolution from 4-20mA. I would say real world accuracy is typically within 0.03mA of actual in that range and similarly within around 0.2mA in the 20-100mA range.Personally, I had no interest in using this for process work, but to fill in the gap below my other clamp meters. Very low DCA is notoriously difficult due to the earth's magnetic field and in the case of the Fluke 771 from what I can tell they have added shielding to the clamp sensor to solve this. You rarely will need to zero out the meter for most tasks, where a typical clamp meter will require regular attention.After running through some bench tests, I found the meter switches ranges right around 22mA, so you do get 0.01mA resolution up to that. Then up to 100mA you get 0.1mA resolution. It does actually measure up to 109.9mA.For electronics use, this mA meter can be pretty handy as a typical DMM has quite a large resistance in mA mode. If you try to use your DMM in series, the voltage drop can greatly impact the circuit.For automotive use (low voltage DC), you can detect leakage and parasitic drains quite easily with this, although in many cases a quality DMM in mV mode across a fuse can do the job with less effort.So what is antiquated? Well, the backlight is terrible, as you can see the 4 LEDs brightly shining into your eyes from the right side of the display. The forward LED can't illuminate where the clamp is. The clamp hinges are very fragile, the spring is far too strong for them and replacements are stupid expensive. None of these models have any communications options for remote work. IR out the back would be trivial. The instruction sheet doesn't fit properly at all in the case, so why even include a paper copy if you can't take it with you? You would think that after all these years Fluke could be bothered to improve SOMETHING? No, they just keep cranking them out as-is. So that is the reason for the loss of two stars here.

I have been using a multimeter for testing 4-20mA for years. It seems that most mfg's are using transducers and plc's these days and not having to shut down and remove wires is a huge time saver. I knew the first time that I used this it was worth the money. Now everyone wants to borrow mine.
