The first is the point-to-point technique, whereby each adjacent pair of contacts is measured. The second is to bus all of the “plus (+)” polarity contacts together, and the same for all of the “minus (-)” polarity contacts.

WebFeb 24, 2016 · Some people call it high voltage testing while some call it hipot testing. Each of these terms can mean different things to different people. Some people think hipot means only a dielectric withstand test. Others see it as covering the whole spectrum of high voltage tests. Still others associate hipot and high voltage with other meanings. WebThere are four main tests that may be performed on the DWV system; which are: Ball Test. A ball test doesn’t check for leaks, but instead insures a proper grade in the drainage pipes. At the local plumbing inspectors discretion he may use a ball to check for adequate grade by inserting it into a fitting; if all is well, the ball will make it ...
