When attempting to do a three-point calibration on a SensION+ MM150, the meter will not allow more than two points, even though the "check" button is not pressed during the calibration. What is causing this?
sensION+ meter does not allow for a three point calibration
The meter most likely has the newest version of firmware. The default on the new firmware is a one-point calibration, as this is best practice. The customer will need to change the number of standards in the meter settings if they need to usemore than one standard.
