Prescaling
To display rotational speeds, circumferential speeds, or other
values based on input pulse calculations, the rotational speed
must be multiplied by a factor input before the input pulses are
measured. This factor is called
a prescale value.
Auto-zero Time (Set before use.)
In operation modes 1 to 6, the time to force-zero the frequency if
no pulse is received for a specified period can be set. This time
is called the auto-zero time. Set the auto-zero time to a value
that is somewhat longer than the longest input pulse interval. (If
the time setting is too long or if the factory-set value is used, the
display may not return to zero even if no input pulse is
received.)

Press the Mode Key for 1 s min. to move to the Setting
Mode.
Select the setup menu ( ) with the Mode Key
and set the operating mode, the input type, and other
settings.
If required, set a prescale value in the prescaling menu
( ).
Set comparative set values in the set value menu ( ).
Make settings in the option menu ( ) as required.
If necessary, generate simulated input for testing the output
function in output test ( ).
After completing all the settings, press the ESC Key to
return to RUN Mode.
