This easy to use Heat Blanket Tester, HCS2047, will identify possible hidden damage to the blanket with a simple “Pass/Fail” feature. This will help to ensure uniform heating of the application by elimination of cold spots associated with blanket failure. With prompting by on-screen menus the repair technician connects the blanket to the tester, enters the voltage and wattage and views the results. The tester can identify open, shorted and intermittent circuits or power leads.
