What is the procedure for testing an RTD sensor?
Follow this test procedure: 1. Verify RTD Place the positive (+) lead of your multimeter on I+ or V+ and the negative (-) lead on V- or I. You should measure the resistance that is expected of the sensor's temperature at the time of this test.
2. 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.
3. 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).
