Performs diagnostics at both startup and during operation to detect short circuits or motor failures.

Set the range to the diode position. Connect the red lead to the anode and the black lead to the cathode. A good diode will show a voltage drop (mV); an open diode will show no movement, while a shorted diode will show full deflection (near 4. Maintenance and Battery Replacement
