Hi JRG,
It is actually REALLY EASY to change the meters from the standard NWare meters to make them reference full scale.
The standard scale of the basic NWare meter has values set at: 35:20:10:4:0:-2:-6:-10:-15:-25:-35
If you wanted to change these values to what is referred to as "Full Scale" the values would need to be changed to: 0:-15:-25:-31:-35:-37:-41:-45:-50:-60:-70
This can be done with the assistance of Inspector.
To start with, you need to have Inspector enabled in your NWare installation. It is easy to turn on, simply go to Tools>User Preferences>Advanced and you will see a check box that allows you to turn on Inspector (it says "Show Inspector (requires application restart)". Yes, after you enable Inspector you will need to shut down NWare and restart it. After restarting NWare, you may notice that the Utility Frame now has another tab that says "Inspector".
On the Inspector tab, you will notice that the list of options change depending on what you have selected in the Design frame. You should be careful what you edit in the Inspector. However, when you select a meter you will notice that there is a field called "ctl_options". On a meter device, these ctl_options are the numbers that represent the values displayed on the meter device. You can double click in the "value" column and edit these numbers directly.
Pro-Tip: You can copy the list of values I provided above and paste them directly into the ctl_options field. Sha-zam! You just rescaled the meters!!!
