The Greenlee QC-MAN-M (52087336) Quick-Check Transformer & Capacitor Tester with Manual 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 Quick-Check & Capacitor Transformer Tester is a versatile tool for quick and easy checks of transformers and the connections made to them. In the field, the Quick-Check 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 Quick-Check 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 Quick-Check can differentiate a true short from the low instance of a transformer winding.

In the shop, the Quick-Check 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 Quick-Check tests both 1Ø and 3Ø transformers, including potential transformers and other instrument transformers.

In addition to performing transformer tests, the Quick-Check tests capacitors and capacitor banks. The tester automatically distinguishes between transformers and capacitors. The Quick-Check tests capacitors individually or connected in capacitor banks. The Capacitor O.K. indication confirms that the capacitor is not internally shorted or open.

The Quick-Check is equipped with a manual self-test tab on its side. The Tester will 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.
