slow speed mode. For example, if you set
+5, 5 mm from the leading edge will be
quenched. [-5~10/2/0.1 mm]
Performs the TD sensor initial setting.
This SP mode controls the voltage
applied to the TD sensor to make the TD
sensor output about 2.5 V. After finishing
this, the TD sensor output voltage is
displayed. Press Start to execute.
You must enter the developer lot number.
(The lot number is stenciled on the top
