Thank you for another great video. It really shows how much effort you put into the reviews. You're making by far the best reviews of DMMs.

The BM789 that I bought after watching your BM786 videos quickly became my most favorite meter.

Thank you for the titanic work done, patience, professionalism. Thanks to you, I have decided on the model of the multimeter. Good luck.

Thanks for the excellent video Joe. I've been hanging for a new video of yours that involves testing and reviewing meters for a while!!. I've learnt so much through your channel and I really appreciate all the hard work and hours that you put into it. Hoping to see more videos like this from you soon (anything to do with multimeters). These videos are helping me stay occupied while in lockdown in Australia.

Thank you for this feedback, it helped me a lot in my choice of multimeter. All your measurements and tests are a mine of information, I admire this work.

Absolutely fascinating and thank you for the excellent reviews and hard work. Just bought the BM869s which is far beyond my capabilities but just got sick of buying cheap meters that packed in on me after short time. Always something to learn in this hobby, regards and best wishes from UK.

Very impressive and thorough head to head review on performance only, not just someone’s opinion! Great job from start to finish, well done and thank you.

This has been most informative when selecting a digital meter, (impressive).

[johnboyd]

Awesome job, very informative and through. Thanks for the update

Thank you for the video Joe! Excellent as always. Just bought one from Welectron. Edit: 78908 firmware installed.

Edit/20220510: Bought a second one from Welectron. Firmware 78908 installed.

Joe, You are the Maestro of meters...

[amham]

I'm a retired calibration tech (metrologist) and always found the Fluke meters to be the most reliable, accurate and responsive with very few not passing spec even over longer periods of use/time (I've calibrated/tested thousands!). However they are expensive. Your Brymen reviews have convinced me that Brymen maybe it's equal at a more attractive price point. I've purchased a couple after your reviews and have not been disappointed. Note, they test well using the sophisticated (and very expensive) Fluke 5520A calibrators.

Okay you had me subscribing after not giving me BS in the into

[janeklof]

Many thanks for a very interesting video !

From Fluke's calibration manual there is a paragraph that states: "For better accuracy when measuring the dc offset of an ac voltage, measure the ac voltage first. Note the ac voltage range, then manually select a dc voltage range equal to or higher than the ac range. This procedure improves the accuracy of the dc measurement by ensuring that the input protection circuits are not
activated.".
What I see from the video at 21.45 the scale is 6.00 (auto scale from AC measurement) and this scale should be set manually for the DC offset for precise measurement (as it is done when you select manually the scale, showing the correct measurement).

Joe. I love my eevblog bm786 so I'm about to pull the trigger on the bm869s off elecktor on ebay. It's quite cheap. I was given a tektronix dmm916 recently. Very nice responsive meter. I'm tempted to mod it with 2 leds. 1 on each side of the screen. I'll run them right from the battery when the meter is turned on. It's going to be a non destructive mod

[francomarianardini]

great video as always!!! congrats Joe!

in uk is quite difficult to get a specific multi-meter model from brymen or other decent or major manufacturers or anything else than a fluke. but i recently discovered a brand that is basically re-branding brymens and they are quite well known as a brand here in uk for testing equipment and they are called metrel.

joe smith, You can measure a current of about 500 mA with a BM789 multimeter in milliAmp mode, take a reading and, without changing the current, switch the limit to Ampere mode (10 A) and also take a reading. For example, it can show 490 mA and 0.500 A, respectively. Will there be such differences on yours or not?
Or it will show 500 mA and 0.500 A respectively.

[yannispreloude]

Hi Joe what is the difference between the bm786 and the BMS 789, and which will have better precise readings overall .There is only a small amount of difference in price I just want to know which is the better one. Great video you are showing all test done to all the metters. After watching the video I think I will get the BM789.

[zxrjimmy]

Still use my 869s, still think it's great
