Testing Power Adaptor Correctly.
Need advice to confirm I am testing a power adaptor correctly, to see if it is working. Please advise what test or tests to do, the mode to use and where to connect the common and positive tester leads. Also what test results to expect.
I did Concentricity, Volt & Amp tests, but the results were questionable. Test Meter: My tester is a RadioShack, Cat. No. 22-805, 24-Range Digital Multimeter, powered by a 9 Volt battery. Power Adaptor Specs.: Brand: YHI, Made in China, Model: YS-1015-U12, Input: 100-120VAC, 60Hz, 0.45 Amps., Output: +12VDC, 1.25 Amps., S/N: 01725948, Symbol beginning left to right: Circle with dash in center connected by short horizontal line to half-circle (like letter C) with dot in the center, connected by short horizontal line to circle with plus mark in center. Thanks much ! Todd
