Hello, What is the input impedance of the 77 when measuring DC voltage?
The Fluke 77 IV Digital Multimeter's input impedance for DC volts is 10 megohms.

Is the 77 IV a true RMS multimeter?
Rated 5 out of 5 by DSchramm from Best DVM I have used ever I got the DVM back in the late 1980s/early 1990s. When I got it, I was in Electronic Circuit Design. Because of a career change to Computer Software Development, I use the meter now at home. It is my goto meter to testing anything electronic/electric.
That means that the battery is now nearly/over 30 years old and I have never had to replace it. That is a great product;
BTW, below it asks how long I have had it. "1 year or longer" is the max entry. I laughed. They should have have entries like 5 years, 10 years, 25 years, more than 25 years.

Rated 5 out of 5 by Calcerttech from Tough, reliable. I worked in the Boeing Calibration lab and would see literally hundreds of these and typically about all I had to do was change batteries and fuses. Issued by toolrooms for production use, sometimes factory, sometimes flightlie. They got torture tested. Under any normal circumstances these are virtually indestructible..

Rated 5 out of 5 by vichardy from Highest Quality, unreal longevity So I worked at Fluke as a designer in the 80's and brought home a 77 prototype. I moved on to another company in '85 but have kept that DVM since. It's been dropped many times and I've gone through I think 3 or 4 9v batteries and it's still going strong after 35 years. Fluke had a robust qualification process that included temperature, humidity, shock, EMI and vibration abuses. When it's time I'll upgrade to another Fluke but I think this one will outlive me.

Rated 1 out of 5 by tech111 from Auto OFF SUCKS! You have both hands involved in what you are doing, look at the meter to start adjusting, and it shuts it self off! You loose your set up as you need to move a hand, NEVER WILL I BUY A FLUKE AGAIN!

Rated 5 out of 5 by EricDiaz81 from Solid meter with great performance. Bought this meter about 6-8 months ago and haven't had any issues. Replaced my old 77 series with this and the newer version is a definite upgrade as it should be. It's voltage range suits well for plc, electronics, and automated service circuit systems troubleshooting. Well suited for field technicians and mechanics alike. Fluke does not disappoint with its rugged package And true test to the elements. I have other meters And nothing is as reliable as my Fluke.
