2 Operations and Functions during Measurement
Hysteresis
If the measurement value is fluctuating around the tolerance comparator value, the comparator
output may repeatedly turn on and off. By setting a hysteresis, a gap may be generated
between the detected value and the return value of the tolerance comparator, thus avoiding this
phenomenon. When the comparator output format is normal, the comparator output is as
follows. Hysteresis is not set by default when shipped from the factory.
Measurement stops while the setting is in progress.
■ Setting procedures of hysteresis
1
Press the key.
Enters the tolerance setting mode.
2
Pressing the key twice shows the Hysteresis setting
screen.
" kYS-1 " sets OUT1, and " kYS-2 " sets OUT2.
3
Press the key, and set the value with the and keys.
In this example, the hysteresis of OUT1 is set to "0.1000".
4
Confirm the data by pressing the key, and press the
key to return to the measurement state.
Refer to "Setting the Output Form of the Tolerance Comparator" (page 3-42) for the
comparator output form.
