Multi-function tool indicates voltage level, tests continuity and includes non-contact AC voltage detection. The Volt Check integrates many functions required for installations and trouble-shooting into one heavy-duty tool. This Smart Meter easily adjusts to the required application without the need to adjust any dials. The integrated Circuit Alert technology for non-contact AC voltage detection uses the only button found on the test unit! Move from continuity testing to AC or DC voltage measurements without making a single adjustment. Magnets molded into the back of the unit allow for total lead control while testing. The versatility of this tester, combined with the ten foot drop rating and two hundred fifty pound crush rating, make it one of the most durable, accurate and safe electrical probes on the market today.
