Fluke 289 True-RMS Stand Alone Logging Multimeter

i am using for the past 5 years working good temperator sensing also perfect

Its the best so far...!

I like the accuracy , look more professional when have it and use it. The machine has great features others don’t. The data logging is very useful for testing and monitoring unseen behaviour electrical signals and current when the car not in operation. I am using it in your automotive trade. Cars now a day have more advance electrical systems. ECU’s are networking together. I need it for the job.

Where to start... The negatives first... 1) I received the meter, and the packaging was absolutely terrible, it was just flopping around inside the box, not in a bag or anything of the sort. It looked like it was a return, that is how bad the packaging was. I looked at some unboxing video's and apparently this is how its shipped. 2) The way the molding is cut left these little yellow flakes all over the place and just seemed like terrible quality control overall. Also there is some dust and a scratch on the underside of the display casing. The scratch is pretty noticeable when there is light on it, but with the backlight on you cannot see it at all. Although it bothers me for a brand new $600 meter, its not enough for me to warrant a return. 3) There is a green dot on the bottom left of the clamshell, looks like a sharpie or something and I tried using 99% rubbing alcohol and the dot just laughed and mocked at me. I guess its staying there. 4) AC Current is not bang on, but is well within spec on the mA range. I forgot to test this when I was taking pictures and don't feel like updating. I have not tested the 10A or uA at all and do not have any standard's to really do so. The Good 1) Every other function on the meter is bang on accurate. It was calibrated in June of 2020 and it is spot on down to least significant digit except resistance obviously. 2) With the LoΩ and the Rel feature, I was able to measure with stability .18 ohm which is compared with the Keithley in 4 wire mode with filters. This took awhile as I left the meter on 30 min and shorted the leads till it was stable and used rel while stable, then measured the low resistance in which it eventually stabilized at the same value of the Keithley. Not the best setup but it was just a quick test. Other then that, resistance did quite well across the board and is well within spec. 3) The meter is very solid and feels good in the hand, it is quite big but with all the features it has I don't mind the size at all. Also the leads it comes with feel really nice and are better then what my other meters came with. 4) Continuity mode is very fast, faster then my Keithley. 5) AC+DC, DC+AC Etc. modes are absolutely awesome, I will use this meter for measurements of that sort because all my bench meters toggle a relay back and forth to do dual measurements. I didn't do much trend capturing, but it comes down to you can either set it to take a sample whenever you want, the lowest being every 1 second, or you can set a specific amount of time that you want it to record so it knows how often to take a sample, because it is limited to 15000 readings. Finally the open circuit voltage in Diode/Continuity is 5.4v at 1mA. It was able to light all standard LED's no problem. The Keithley in the pictures is in cal. and is spot on, the standard used for testing was the DMMCheck Plus r6. Overall it is a great meter, but either mine was in a rough batch or Fluke's QC absolutely sucks, because there were some issues and for the amount you pay for this meter it should be flawless. Edit: I uploaded the pictures in order, but Amazon kinda threw them all over the place. Voltage readings have both meters, and resistance they are done separately.

Love this meter, it's my workhorse, in use every day in the mechanic trade, never let's me down, except for when I pop an internal fuse ... my fault, not the meters. Do yourself a favor and get a few of each of the internal fuses (2 kinds) and you'll be set to tackle anything.

This items meet more than my expectations
