interesting how immediately after the 9.18 calibration the meter reading showed the sample at 9.57, not sure how much these meters can be trusted for accuracy.

Hola, solo se calibra una vez para usarlo? O es necesario estar calibrándolo siempre?

Good afternoon. The factory instructions recommend the calibration order first 6.86 then 4.00 and only then calibration is done at 9.18? But your procedure is not the same. How important is this for proper calibration of the device?
