Change Zero:
This button automatically zeros the meter.
To perform this zero procedure, you must make sure that the actual flow is zero.
Attempting to zero the meter or controller while there is a flow condition will cause
an offset. Note: This MUST be done using the appropriate gas as selected.
Caution : do not perform auto zero when there is no gas present in the meter and or
the gas is FLOWING.
Default zero:
This will set the zero value back to factory conditions. Use this in order to recover
from a mistaken entry.
