Aquant Plus 2 moisture meter

[Sailorman Ed]

My new project boat came with a Aquant Plus 2 moisture meter but wo any documentation. I cannot seem to find any info on this older model made in the UK, only the much newer GE models. Does anyone have one and could share how to interput the results? ( there are a series of LED and also 3 scales). I know I have some balsa core issues in the salon roof/walls.
thanks in advance, Ed

Just putting this away and noticed the cover has a square bulge on it suggesting maybe it came with an included "standard".
