Turnigy meter question

When a Turnigy is used to monitor charging, the charging source is the source side, and the battery is on the load side. If the charging source is off, will the meter show the battery voltage? It doesn't seem so from what I see of it.

There is an aux power input. If that was powered up, would it then register batt voltage in the above scenario?

Thanks.

    yes, one heavy duty power lead , the negative aka wire is attached to the built in shunt

    put the meter on the battery side of the contrtoller,
    Not the panel side
    measure what is going ino the batteries
    attach red wire of meter, with or without switch to the red wire going to batteries
    meter will always have power

    I also have the same meter. The right side of the meter is the load side (battery) and the left side is the Source (panel) The switch is needed in battery side so as to Disconnect the battery power (Red) for two seconds to reset for data readout. I've read the two reds are tied together in the meter. Hmm lot's of fun

    I have my Watt Meter just handing below the MPPT controller in the shop connected to my 24v/120w Cynergy Panel and two 12v batts in series.

    My Watt Meter was mfg for SUN-BORN Energy by Turnigy It's on EBay at $42.95 plus shipping.

    Yeah, I watched a bad, boring youtube video where the guy took one apart, and the reds are both soldered to one point. It probably has a shunt on the negative side, and does the math from that and the volt readings.

    I got Mr. Wizard's part about using the switch to reset, but wasn't sure about his wording on the overall hookup. Now I get it, assuming you and he are describing the same thing. Well, I've got one coming, although from where I have no idea, lol. I don't know if it's going to take 5 days or 5 weeks.

    mine shows battery voltage
    i get to record the overnight low voltage

    mine is wired to the battety/output side of the controller going to the batteries
    so the power red lead is connected to the batteries charge line, thru a switch i use as the reset
    so it reads battery voltage even when the solar is off
    every evening after taking my daily reading, i hit the reset


    I'm sorry, I'm still confused. :)
    Are you providing battery power to the unit when the solar is off?
