No continuity
Grounded Bolt Coulter terminal
3) Implement Test Box – To properly measure conductivity, good electrical continuity must
be present from the coulter electrode to the instrument. The Implement Test Box (Part
No. 10759) allows you to quickly check this.
Use the following method:
a) Connect the signal cable to the terminal on the test box.
b) Touch one lead of an ohmmeter to the #1 coulter blade (left hand, standing behind
the unit) and the other lead to the #1 terminal on the test box. A reading of less than
2 ohms is normal.
