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.

Voltlog #139 – Aneng AN8009 Multimeter Review

In Voltlog #114 I reviewed the Aneng 8008 and I said it’s probably the best $25 multimeter that you can buy. Today we are taking a look at the Aneng AN8009 which is a newer model from Aneng. 

In the end I would say this new AN8009 model is just as good as the AN8008 and they are both great beginner multimeters but they can also be good for the more advanced user who better understands their limitations.

My recommendation is to take a look at the differences between the two and choose based on your needs: ask yourself, do I need temperature measurements? Do I need the extra resistance range? Or do I need the square wave output. Better yet, and this is what I would do, I would get both models to have all of those functions when needed. Also it’s good to have two multimeters because you can measure both voltage and current at the same time.

Here are some links where you can get the Aneng 8009:

Voltlog #115 – Pure Sine Wave Inverter Circuit Waveforms

This is a followup video on the 300W pure sine wave inverter I reviewed a couple of weeks ago.  A couple of people we’re curious how the output mosfets are switched in order to obtain that nice looking sine wave on the output.

Voltlog #113 – 300W Pure Sine Wave Inverter Review & Teardown

Today we are taking a look at a 300W pure sine wave inverter which was provided for free by banggood.com for the purpose of this video. First we take a look at it’s output on the oscilloscope and then we continue with a teardown of the inverter.
