Voltlog #253 – Aneng V01A Multimeter Review & Teardown

Welcome to a new Voltlog, today it’s a multimeter review because we haven’t done one in a while and here I have the Smart Digital Multimeter which sounds like a generic name, no obvious branding on the box but granted it is featuring the multimeter on the box, it’s a color image which is not often seen on these cheap meters. On the back, the meter is shown in full black holster and we get a model number sticker, AN-V01 so this probably indicates the Aneng brand.

We’ve looked at Aneng multimeters in the past in Voltlog #114 and others and I’m gonna say this again, Aneng does not make multimeters, Aneng is just a company that rebrands existing multimeters made by other companies.

Voltlog #152 – Fake Aneng AN101?

So back when I was preparing for that video, I ordered an Aneng AN101 from aliexpress, I think I took the cheapest seller out of the ones that were available and when I got the meter I realised it doesn’t have the Aneng branding right here on the upper side of the LCD.

Voltlog #148 – Affordable Pocket Multimeter Shootout

In this episode we are going to be taking a look at the affordable pocket multimeter market, I’ve god 4 models which you can get for under $20 and I’m going to review these to see which one is best.

If you just want to skip to the results checkout this spreadsheet on google docs.

Voltlog #131 – Measuring The Efficiency Of The Ruideng Kis3r33S DC-DC Converter

You might remember this small module from the previous InTheMail, this is the Ruideng dc-dc converter with a claimed efficiency of 95%. Now a figure of 95% efficiency is not unheard of these days, many dc-dc converters can achieve this with proper circuit design.

This particular model uses the MP2307 converter chip manufactured by Monolithic Power and if we take a look at their datasheet we can immediately see where they got the 95% efficiency figure they advertise.

If you own fancy equipment like a source/measure unit than one instrument can do all the measurements and data log the results as well but a source/measure is out of our budget so we will be using multimeters for this test.
