What is the procedure for testing a diode sensor?
Ensure that your multimeter is rated to measure resistances up to 10 megohms, then follow this test procedure: 1. Verify diode (part 1) Place the positive (+) lead of your multimeter on I+ or V+ and the negative (-) lead on V- or I. You should measure approximately 5 megohms at room temperature.
2. Verify diode (part 2) Place the negative (-) lead of your multimeter on I+ or V+ and the positive (+) lead on V- or I. You should measure an “open” (infinite resistance).
3. Verify sensor leads: measuring between the I and V leads - Measure the resistance between the I+ and V+ leads. You should measure the total resistance of your wire. - Measure the resistance between the V- and I- leads. You should measure the total resistance of your wire.
4. Verify sensor leads: isolation - Place one lead of your multimeter on I+ or V+ and the other lead to your system ground. You should measure an “open” (infinite resistance). - Place one lead of your multimeter on I- or V- and the other lead to your system ground. You should measure an “open” (infinite resistance).
