I don’t think there’s a way to mess up the first button press to calibrate. Once that’s done then mix contents of packet for 2 mins as stated.
I spoke with the folks at Hanna once and they said they do add a bit of extra powder to the packets to make sure. I’ve found it hard to get all the nitrate packet out but no problems with the phosphate.
It would be easier if they maybe sold the reagent in capsules vs packets.
