From Sears’ weekly circular: a Digital Multi-meter (#82140) with an AC voltage detector (#82174) for $12 — 50% off the regular price. The multi-meter measures both AC and DC voltage, current, resistance, diodes, and continuity. It’s also fuse protected, and it comes with two additional fuses. The AC voltage detector lights up when exposed to 120 or 240V at 50 or 60 Hz.
