OIL PRESSURE SETUP
Dakota Digital only offers one pressure sensor for this system, SEN-03-8, 0-100 psi solid
state sensor with 1/8” NPT threads. The Oil Pressure setup allows you to set up a low pressure
warning point that will cause the message display to flash the oil pressure reading whenever the
value is lower than the warning set point. There is also a test mode that will display the voltage
from the sensor for trouble shooting assistance.
Press and hold SW1 while turning the key on. Release the switch. Press and release
SW1 to enter the “
