CHAPTER 5 OPERATION
5-20 Specifying the Auto-zero
Time
(K3MA-F)
This parameter allows you to specify the auto-zero time.
The auto-zero time is the length of time required for the product to return the readout
to zero after pulse input interruption.
Set this parameter to a larger value than the expected time interval of input pulses
(interval between pulses). Failure to do so will result in incorrect measurements.
If auto-zero time is too long, on the other hand, a long delay in lower-limit action in
response to a stop of rotation may result.
In the following application where a pulse is produced per rotation at 12-6000 r/min, for
example, the input pulse frequency is 0.2 to 100 Hz, which means the time interval of input
pulses is 0.01 to 5 seconds. The auto-zero time should be set to five seconds or longer.
Procedure
A. When the product is at the operation level, press
the L key and hold it down for at least three
seconds to enter the initial setting level.

C. Press the M key several times until parameter
"auto.z" appears on the main indicator.
D. Press the S key to display the set value of the
parameter on the main indicator.
• The current set value of auto-zero time will
appear on the main indicator.
E. Press the S key again.
• The set value will start blinking, indicating the
product is in the change state.
