===== pseudo Tests with Timegrapher =====

Ignoring Temperature Variations. 

Make 2 measurements on Timegrapher in each position, separated by 24 hours and record them in table:

^Day^Pos^Daily rate^Variance^
|1|6H|M1|  |
|2|  |M2|V1|
|3|3H|M3|  |
|4|  |M4|V2|

|7|Ddn|M7|  |
|8|  |M8|V4|
|9|Dup|M9|  |
|14|6H|M14|  |
|15|6H|M15|  |
