VIPER PRO CALIBRATION AND OPERATION
FIGURE 35. Sensor Status Screen
• The Yaw Sensor Status area of the screen displays the yaw sensor diagnostic information:
◦ Current Wheel Angle - An approximation of the machine’s wheel angle.
◦ Current Sensor Reading - The current value of the encoder.
◦ Zero Yaw Button - Recalibrates the yaw sensor to zero. The machine must be at a full stop before
recalibrating the yaw sensor.
◦ Yaw Zero - The yaw sensor reading while the machine is stationary. The acceptable operating range for
the Yaw Zero measurement is -2.00 to 2.00. Readings outside this range indicate that a sensor within the
node is operating outside of specifications and that the node must be repaired.
◦ Encoder Cal - The ratio of the steering wheel movement to the machine’s wheel movement.
SYS DIAG SCREEN
The System Diagnostics screen contains the PWM values and system input diagnostic tools.
