Default Newbee question about Rx

Okay, tommorrow looks like a great day to get out and work out my newly received solo wings. I decided to do some checking on my batteries.

Now, I turn on my 6EXAS Futaba radio. 10.8Volts. Okay, probably top that off tonight with the wall charger tonight. I double check this with the El Cheepo Multimeter. And it shows a little over 10V. I've read the manual that came with the 6EXAS and understand the whole Tx voltage ranges regarding when to fly, when to start thinking about a charge, and when to panic.

The receiver charging protocol is where I'm getting hung up.

I can't figure out a good way to check the Rx battery using the MM leads. I have a Hanger 9 Double Vision field charger (thanks LowLevlflyer!) that has ports for the MM leads. So I plugged the field charger up to the Rx and left the charger unplugged from the battery (just using it as an interface between my reciever batteries and my MM). The charge on the multimeter is showing about 9.0V. I went ahead and plugged the field charger into the field battery and the bar graph on that shows 80% on the reciever battery.

My questions are:
1) How the heck am I getting a 9.0V reading from a 4.8V battery?
2) What is the Normal volt range/low range/panic range for a standard 4.8V battery?
3) Do I need a new Multimeter?

Also, what is odd, is that when I check the field battery Volts on the multimeter, I show right at 24Volts (on a 12 Volt battery!)

I'm lost, please help!
