Sounds right. The Kiwi video is quite good. I am honestly not sure of the exact process. But it might be an idea to start with getting each bucket to tip evenly and get it as near as you can to 6.28ml per tip. In theory if you get this exactly right and put 0.200 into the TX. Then 314 ml of water should result in 50 tips and 10mm on readout. I expect you will need to do small adjustments when you use 314 ml or 628ml as it will be difficult to measure one tip accurately using home / hobby equipment.

I had a quick look at the Dutch website. My kindle won't translate but if I read correctly he says 4 grams = 0.2mm . This can't be right, it is definitely 6.28ml (or grams) for a 0.2 bucket / gauge, but maybe it is my Dutch that is lacking. Looking closely at the makers plate, his is the 0.5mm bucket which means 20 tips will = 10mm . Each bucket tip will contain 15.7ml.

You could change TX to 0.238 (10mm / 42tips = 0.238). Given the numbers you are coming up with I wonder if your gauge has been calibrated as an imperial gauge, though Australia has been metric since the 60's I think. If it was, then I expect it would have been set to 0.254 or 1" = 100 tips (25.4 mm ) (0.01" per tip). I expect your gauge dates from the 1980's so it is possible.

The balance I think will alter the tip side to side. The set screws below the buckets will alter the volume. I expect you will need to do both simultaneously to get it right.
