Zero a FieldLab

Reset the FieldLab pressure readout to zero when there is no pressure applied to it.

Sometimes, due to atmospheric pressure, the FieldLab will show a negative or positive pressure when there isn't actually any pressure applied to it.

When that happens you can easily reset the FieldLab by pressing the Zero button.

With no positive or negative pressure applied to the FieldLab, press & hold the Zero Button down until a message displays saying that the FieldLab has been Zeroed.
