When in this menu, the first button becomes the ZERO button. When this button is
selected, the most recent ADC value after averaging will be loaded into the ZERO
register.
Zero calibration is also enabled or disabled by pressing the ZERO button. This is
indicated by a change of the spinning character on the far top-right of the display, (i.e.:
a LINE is inserted under the spinning character when zero calibration is turned ON.)
When enabled, ZERO
