PROCEDURE TO TEST FLOW METER CABLES:
PROCEDURE TO TEST FLOW CABLE:
1.
Enter a meter cal number of 1 in the key labelled METER CAL.
2.
Depress key labelled TOTAL VOLUME.
3.
Place boom switches to ON.
4.
With a small jumper wire, short between the 2 o’clock and 6 o’clock sockets with a “Short, No Short” motion.
Each time a contact is made, the TOTAL VOLUME should increase by increments of 1 or more counts.
5.
If TOTAL VOLUME does not increase, remove the section of cable and repeat test at the connector next closest
to the console. Replace defective cables as required.
6.
Perform the above voltage checks.
7.
If all cables test properly, replace the flow sensor.
