For clarity, which version of the meter are you referring to? I ask because the names of the different models vary depending on where the meter is distributed from.

For one of my meters at least (I have two, and they are of different vintages) they are badged "Lunasix 3 and they have both a "Transfer Scale" and an "EV Scale". If you are reading from the "Transfer Scale" it will yield numbers that are 3 more than the corresponding numbers on the EV scale.
