This is the current voltage of your 2 leisure batteries. In this case its a normal, good number/value. If you want to know which values are normal (when on hookup, when driving or when using the batteries, search the forum.)

This is the amount of ampères that is going into your batteries. They are charging. If the number is proceeded by a '-' (i.e. when the number is negative) it shows how much ampères are being drawn from your batteries at that time.

Finally, a friendly and well meant word of advice. Please read it that way. A lot of people on the forums here are very kind, knowledgeable and willing to help out with tough problems or easy questions alike. However, people tend to be more willing to help, if you show you have browsed the manual and/or searched the forums. Because this information can both be found in the manual as well as in the gazillion of older threads in this forum that make this forum so usefull. Much like an encyclopedia.
Hope this helps. Don't hesitate to ask more questions
