Try This At Home

Will the insulation tester detect problems that a regular digital ohmmeter won't? Find out! Try this on one type of insulation problem: water on the wiring.rnSpill a little tap water on a clean counter. The puddle should be about one or two inches in diameter. Just don't add any salt or other contaminants to the water. Measure the resistance of the water using a regular digital ohmmeter, keeping the tips of the probes at least 1/2 inch apart as shown in Figure A.
