Firmly press one lead of the ohmmeter to the #1 coulter blade edge (left hand, standing behind the

unit) and the other lead to the #1 terminal on the test box. Maintain firm pressure on the ohmmeter

lead touching the disk blade. A reading of less than 2 ohms is normal. Rotate blade ¼ of a turn

back and forth as you view the ohmmeter. Any jump in the readings above 2 ohms indicates a

problem.

Continue to check each coulter electrode in succession, left to right.

If any coulter electrode exhibits no continuity or resistance higher than 2 ohms, refer to Procedure

#3 Diagnosing EC Signal Problems.
