Testing Diodes ( / ):
• Slide the function switch to the Ω/ / position.
Note: The measurement mode defaults to Ohms (Ω).
• Press the Ω/ / button twice to toggle to the Diode test mode. The meter
display should show the / in the upper right corner.
• Ensure the circuit is de-energized to prevent inaccurate readings.
• Apply the red test lead to the anode of the diode and the black lead to the
cathode (gray ring). Verify the forward voltage drop is about 0.6V for silicone.
• Reverse the test lead connections. Verify an "OL" reading in the display.
• If the diode is shorted, 0mV will be displayed.
• If the diode is opened, "OL" will be displayed both directions.
Note: Audible indication occurs at <0.25V.
Battery Replacement:
• Ensure test leads are disconnected from any
circuit or components.
• Remove the screw from the battery cover.
• Remove the battery cover.
• Replace batteries with two 1.5V button cell
batteries.
• Assemble the back case on the meter and re-tighten the screw.
Maintenance:
• Clean the case with a damp cloth and mild detergent. Do not use abrasives or
solvents.
