Auto-zero Time
Due to the principle of forecasted cycle calculation, the frequency will
not become zero even if the input signal is cut off. Refer to " Forecasted
Cycle Calculation" (P.A-30) for details on forecast cycle calculations.
When there is no input pulse for a specified time, auto-zeroing can be
used to force the measurement frequency to zero. The time from cutoff
of the input pulse to the zeroing of the measurement frequency is
called the "auto-zero time."
