    Exclamation The State of the Power Meter Address

    Ladies and gentlemen... it is my privilege to report that the replacement shunt resistors for the Brand 4-1850 have arrived, and one has been swapped into the meter.

    With the help of next week's review sample, I have just completed testing of the Brand meter. What are the results?

    Folks, the Brand 4-1850 has been successfully repaired. Not in time for next week's review, but it is among the accurate once more. Actually, it's tracking better with 80 Plus than it was even before it failed.

    So, until the IDRC meter gets here, the Brand will once more assume its normal duties here at Wolfie's Lab of Insane Cackling and Power Supply Destruction.

    That is all.

    A long overdue update. The new power meter has been ordered, and it is not from IDRC, GWInstek, Hameg, Weibo, Lutron, or even Everfine. The owner of the IDRC ended up needing it yet, so I had to go for something else.

    I bought this:

    A Rek (Meiruike) RF9901. Their eBay listing claimed there's a 110V version, so that's what I asked for. Pics to come when it gets here.

    It looks like the Everfine PF9901 except with an outlet on the front:

    I get the feeling there's a lot of, shall we say, "sharing" of ideas between a lot of these companies.

    if the ±0.4% is real (which I doubt) then its a good deal for its money.

    Anyway we are waiting for your first impressions once you have it


    ps. I am also on the search for another power meter since the serial port of mine is giving me lots of trouble (it frequently loses communication with my program). Except from this I am very pleased with it.
    I am saving money to buy a Hameg 8115 (which has USB).

    I doubt it's that accurate too, but we'll see. I have two other power meters to compare against.

    at least it has a good price. I have to find 600-650 euros to buy the Hameg and thats without the load cables (although thats not big problem since I will make them).

    Yeah - it's also a little more full featured than the Everfines I could find on eBay.

    It's going to be nice to be able to tell at a quick glance what the power draw is. The Brand's display is an unlighted LCD and the green display on this meter will contrast nicely with the all red displays on the SunMoon. Every power supply review will seem like Christmas came early

    yeah here's another 9901 but without the front outlet:

    the 9800's should have slightly better accuracy with the additional current ranges
