The instructions are much more specific than what you're showing. There should be a timer used, and the #2 nitrate bottle needs to be shaken a lot before use. I work in a medical lab, and following instructions for testing is very important. Hopefully, no one is getting incorrect readings, but it is certainly possible. ALWAYS, read and follow instructions.

Oh ok! Wow, I had no idea. Generally this works fine though but thanks for your clarification.
