Figure 2.2

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

unit) and the other lead to the terminal marked #1on the Quad 1000 test box decal. 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. (Figure 2.3)
