Turnigy Wattmeter auxiliary power function

[Fordulike]

Has anyone connected an auxiliary power source to keep the display alive, when the source power is shut off?

Also, does the auxiliary power function allow it to retain it's memory from one day to the next, when the source power is shut off?

If you wanted that could you just not wire it in before the switch for the battery?!?
If not you could change the switch in the negative position to actually create a live to keep the watt meter going.

Any idea of the standby current drain on one of these meters?
Can't imagine it to be much.

I've left mine on while at work for about 12 hours in total and the volts dropped from 47.63 to 47.02v across a 10amp pack so I don't think it's that much.
It's more than some simple meters but it's by no means high. I wouldnt imagine more than a few watts for an hour If that.

Intact it's less than what I said as I leave my batteries running all sorts.
