Heater Testing Simplified With the Wound Component EST Scanner Model 19035

At a minimum there are two production tests which all heater manufacturers perform in addition to ensuring the heater is operating properly. One test performed is a DC resistance test; the other test is a dielectric withstand test, more commonly known as a Hipot test. In many cases two pieces of test equipment are used to accomplish these two measurements. The Wound Component EST Scanner Model 19035 has combined these measurements into one instrument. This provides the advantage of performing both tests with a single connection to the heater or Device Under Test (DUT).

Simultaneous Hipot Testing

This application note investigates whether a tester will detect a failure when testing multiple components at once, or will the other parts “mask” the failed product.
