Thanks for your suggestion Fabian,
I have tried both: PROCESSING "SCALE=<low>:<high>" PROCESSING "SCALE=AUTO" but with no change....with outputformat set to jpeg, I get a white image, with outputformat set to PNG, I get a very light grey image....but that is all!

Mapserver truncates this to 255 which interpreted as white on a greyscale. To correctly scale the values you can use band processing options: PROCESSING "SCALE=<low>:<high>" You can also use "AUTO" but that might result in strangely "tiled" images.
