The Analyzer Zero Warn is set to ON at the factory to remind you to zero out any offset
in the Flow measurements. The Zero Warn screen reminds you at power on, after the first
five minutes, and then after each 30-minute period. After the power-on zero warning, you
can choose to Zero or Cancel when the reminder appears; either action returns the
Analyzer to the same function.
