X3 on the vapor charge and I like the converting to grams. It's got more increments for more accuracy.
If you switch to grams you'll have much smaller increments, but the accuracy of the scale remains the same.
My (POS) TIF scale has a resolution of +/- .5 oz and will read out in kg to 2 decimal places...ie, 0.00 kg. That means it's lowest possible results would be in increments of 10 grams...which is still less than .5 oz.
So my stupid scale won't even register anything until you're up to about 20 grams.
Put the entire machine on the scale, since it is 134A you can charge it vapor.
Great in idea, very difficult in implementation. Such a scale is very costly and not portable.
They have such high capacity, high resolution scales for such thing as measuring grams of tread worn out on a tire after a test run with the wheel still attached. They're something like 50,000g x 0.1g which requires a 500,000 count resolution.
Your average 220 lbs x 0.25oz charge scale is 100,000g x 10g which is only 10,000 counts.
Do they have such thing as an adjustable metered dose injector that lets you dial-in the charge in 0.01oz increments and allow the injector head to mount close to the port?
