2-214 TD Sensor
Initial Setting Performs the TD sensor initial setting. This SP
mode controls the voltage applied to the TD
sensor to make the TD sensor output 2.5
±
0.1
V.
After using SP2-214, check SP2-220 to see if
the sensor is working correctly.
This mode is started by pressing the Start key
and stops automatically after about 2.5
minutes. Use this mode only after adding new
developer.
