5. Set the lower limit value for sensor head 2.
Touch again.
Set the lower limit value in the lower limit value screen
for sensor head 2.
6. Return to the MENU screen by touching or
return to the input/output screen by touching .
Reference Input Range: Upper Limit Value, Lower Limit Value = ±999.9999 mm
Set values so the upper limit becomes larger than the lower limit.
Default Settings:
Sensor Head 1 Upper Limit Value = Add/subtract Calculation Upper Limit Value =
+5. 20.0000mm
Sensor Head 1 Lower Limit Value = Add/subtract Calculation Lower Limit Value =
-5.0000mm/- 20.0000mm
Sensor Head 2 Upper Limit Value = +5. 20.0000mm
Sensor Head 2 Lower Limit Value = -5.0000mm/- 20.0000mm (50mm type/85mm type)
„ Hysteresis Setting
Set hysteresis for upper and lower limit values to prevent chattering. Because the
resolution changes based on the workpiece measured, the average number of samples,
and so on, set operating conditions and use the P-P mode to obtain an estimated
resolution before setting hysteresis. Hysteresis can be set for each sensor head
.
1. Display the upper limit hysteresis screen from the
input/output screen.
Touch on the MENU Screen. The input/output screen
is displayed.
Touch
on the input/output screen to open the upper
limit hysteresis screen. The current setting and a keyboard for
inputting value are displayed.
2. Set the upper limit hysteresis.
Input hysteresis for the upper limit value of sensor head 1.
Hysteresis works evenly in the upper and lower value areas
around the upper limit value.
For details, see the description "Hysteresis" below.
For keyboard input method, see page 4-2.
