Ok, something off then. I filled with 1 ml bac water then used different settings to back fill a 1 ml syringe. Needed it set to 16 units to hit 1/10th ml. Cripes, guess I keep messing with it a bit...probably put a full 3ml in the reservoir and try it . Appreciate the info though. I think once I have dialed in itll be nice and convenient.Normal pens are set up for U100 insulin, 100 units per ml. U40 is insulin for pets (with syringes matching standard dilution botox). Never heard of U60.
With U100 pens from Lilly and Chinese clones, 10 units is 0.1ml. One unit is 0.01ml. Cartridge holds 300 units (you lose the last 5 or so units due to dead space at cartridge throat)
