Calibrates the process value to zero forcibly if no input pulse is received for a
certain period. This period is called auto-zero time.
Refer to the following graph.

Logically, the input pulse frequency does not drop to zero perfectly due to the
estimated frequency calculation of the K3NR. Therefore, the K3NR has a func-
tion to calibrate the frequency to zero forcibly if no input pulse is received for a
certain period.
Automatic zero time is determined by the following formula.
Auto-zero time = X x 10
Y
(s) (X: mantissa, Y: exponent)
Note Auto-zero time must be longer than the value obtained by dividing
one by the minimum frequency input of the K3NR. Auto-zero time
must not be less than 0.1 s.
If the operating mode of the K3NR is set to F7 (pulse counting), this parameter
will not be available.
