HD Electric Quick-Check® Transformer and Capacitor Tester (QC-MAN-M)

HD Electric Quick-Check® Transformer and Capacitor Tester (QC-MAN-M)


The Quick-Check® 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 primary and secondary sides of a new or reworked, single or three-phase transformer installation for short circuits prior to energizing. Unlike a simple ohmmeter, the Quick-Check® can differentiate a true short from the low resistance 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.

The Quick-Check® also tests capacitors and capacitor banks. The Quick-Check® uses the same single push-button operation as the TILT II and automatically distinguishes between transformers and capacitors. The Quick-Check® test capacitors individually or connected in capacitor banks. The Capacitor O.K. indication confirms that the capacitor is not internally shorted or open.
