circuit and discharge all capacitors fully before making continuity measurements. 4.5 Diode test • Turn off power to the circuit. Allow all capacitors to discharge. • Set the rotary switch to the multi-function position. Press “FUNC” once to enter diode mode. • Connect the red test lead to the input jack and the black lead to the COM jack. • Connect the red test lead to the anode (+) and the black lead to the cathode (-) of the diode and read the measurement on the display. The meter will display “OL ...
