    We'll see. I got the only one I could find on eBay with a 120V option, so that gave it an edge for me. Even if I do have that 1kW step up transformer I never use

    I eventually changed my mind and I will go for the GW Instek 8212R (today I checked both manuals of Instek, Hameg). Mainly because it has auto-calibration (and 0.2% accuracy vs 0.8% of the hameg).

    I was really hoping for green displays:



    This is me pulling about 770W out of a BFG EX1000. First impressions - this meter is considerably more accurate than the Brand or the KAW, though the Brand was a lot closer to being accurate than I ever thought.

    Thanks to this wee beastie, I can actually consider doing standby efficiency tests now. This thing reads to three decimal places with really low loads. Will have to give that some more thought.

    They did indeed send me the 120V version as requested. That outlet on the front is actually a multi-way deal that lets you plug damn near any worldwide AC connector into it. All I need to do now is get some proper 12 gauge stranded wire to connect the load terminals to the wall, and I'll be set. For the time being, I'm using some of the old 12/2 I used to wire the 20A dedicated load testing circuit. Not a permanent solution, but it'll do for now.

    Nice!!! One irrelevant question. Did you make by yourself the patch board for the PSU connectors. I am still trying to locate one , although I don't need it for the moment.

    Nope, it came with the SunMoon. I did have to do some rewiring to it though... those big 12 gauge wires running off the top of the picture are for the auxiliary loaders, which are on a shelf near the ceiling. Many of the existing cables also needed replacing due to too much voltage drop.

    in 2 days I will have my new power meter (GPM-8212RS) and I hope my new oscilloscope, too.

    Photos coming

    I also bought a Fluke 175 (although I do not need it since I have the labjack for all measurements but I found it in a good price)

    The Instek came and it rocks

    I didn't have the time to take some photos because since yesterday I am trying to connect it with my program. Unfortunately its programming is a little tricky. .
