Just got my new Aneng AN8009 Multimeter in the mail. I’ve made an old post about improving the responsiveness of the Aneng AN8008 in an earlier blog post. I loved that meter, but I gave it to my son who is just beginning on his electronic journey. So naturally, I needed a replacement. After checking eBay, I found that there’s a new model, the Aneng AN8009 so I decided to get that model. It has the same problem that the Aneng AN8008 had; it’s slow to settle on a value when measuring. Fortunately, my old modifications work on the Aneng AN8009 as well.
If you are on the lookout for a sub $30 Multimeter (or $15 on eBay) for working with low voltages, the best one right now in my opinion is the cute and tiny Aneng AN8008 TrueRMS Multimeter or the newer model, the Aneng AN8009 with NCV and temperature measurement. They have a lot of functions and can measure µA current, and both are a 9999-count meter. The continuity tester is reasonably fast, but there is one little problem that bothered me. It takes 5 to 10 seconds for it to settle on a correct voltage reading. When it finally ends, it’s spot on, but the waiting is annoying. But fortunately, there is a simple fix for this problem.
Easy Way To Calibrate a Bryman BM869s Multimeter
After replacing my lost Fluke 87V multimeter with a new Brymen BM869s (rebranded Greenlee in the US) about a year ago, I’ve been delighted with the multimeter. It has every possible function I could ask for and then some. It’s been my go-to meter when working on electronics projects. I do have a Siglent SDM3055 DMM that is very good, but due to its startup time, I usually reach for my Brymen BM869s when I need to measure something, and it has higher resolution. But after getting a broken HP/Agilent 34401A DMM from eBay, fixing it up and replacing all the capacitors, I now have a better reference. I’ve compared it to a friends calibrated 6 ½-digit multimeter, and it’s still within spec, so naturally, I want my Brymen to be as close to my HP 34401A as possible. Turns out that calibrating and adjusting the Brymen is quite easy. Here’s how to do it.
