The Greenlee TL-AST-M (52087335) TILT-II Transformer Tester with Automatic Self-Test and Magnet Mount provides quick and easy tests for opens and shorts on power distribution systems. It operates with a single push-button and provides clear indications of open circuits, short circuits and confirmation that the test results are OK.

The TILT II (Transformer Initial Livening Tester) Transformer Tester is a versatile tool for quick and easy checks of transformers and the connections made to them. In the field, the TILT II is used to test the primary and secondary sides of a new or reworked, single or three-phase transformer installation for short circuits prior to energizing. The TILT II can test the secondary sides of transformers and all the connections made to them, up to and including the meter, prior to energizing. Unlike a simple ohmmeter, the TILT II can differentiate a true short from the low instance of a transformer winding.

In the shop, the TILT II can be used for quick screening of incoming and outgoing transformers for both primary and secondary shorts or opens (including internal fuses and breakers). The TILT II tests both 1Ø and 3Ø transformers, including potential transformers and other instrument transformers.

The TILT II is equipped with an automatic self-test. The Tester will automatically perform a complete self-test of the battery, lights, beeper and all electronics every time the TEST button is pushed. The unit also features a magnet that allows for hands-free operation.
