I am curious about how much difference there is in accuracy when one kit is trained for 30 minutes, 1 hour, 1 day, 3 days, and 7 days, respectively. 2. I am curious about the measurement period. (The period I was thinking of was Test Day 7.) 2-1 Since stool is decomposed, do I need to measure it continuously for 7 days with one kit? 2-2 In other cases, do I need to measure separately on the 1st, 2nd, 3rd, 4th, 5th, 6th, and 7th days? @BSTRobin  ...

After bringing the magnetic material close to the board and observing the graph phenomenon, the magnetic material was moved away from the board. It is normal for the graph to return to its initial state, but I am curious as to why it does not return. (A photo is attached.) Photo 1. normal normal   Photo 2. error error ... View more
