5.6 Setting the Auto-zero Time
The display is forced to zero when there is no pulse for a specific
period of time.
* The input B auto-zero time can be set only for function F1 or F6.
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.”
