Important Notice: Low voltage electronic transformers must be tested under load with a analog meter to achieve accurate results. Testing the transformer with a digital meter will produce an invalid reading of "no output". This characteristic is unique to electronic transformers that produce a square sine wave. We recommend use of an analog meter for testing with the transformer loaded to at least 20% of its rated output. Most electronic transformers returned as defective are actually good due to testing methods in the field that did not follow the above requirements.
