Capable of measuring 6 functions on 14 ranges on it's easy-to-read color-coded analog display you'll find yourself reaching for this handy unit almost every time. Unit tests AC and DC voltage, DC Current of Resistance, and common household batteries from 1.5V thru 9V. Unit includes built-in Zero Ohms adjustment dial allowing you to reset prior to resistance testing and to perform internal battery test function. Unit incorporates fuse overload protection circuitry to protect the user and a mirror scale is provided to reduce the possibility of parallax errors. Common measurements with this unit include: testing household batteries for charge level, troubleshooting various low voltage circuits, testing wall receptacles for proper voltage and grounding, and troubleshooting electrical cords, strings of lights, fuses, and switches to determine if they are operating properly or if a break in the circuit exists and the item in question needs to be repaired or replaced. The decibel feature of this multimeter is used for transistor gain measurement in electronic circuits and should not be confused with audio decibels. If you are looking for an all-around electrical tester you've found an excellent choice.

It will tell you how to use the tester. Where the tester lead cables are inserted. Where to turn the dial to do the specific test. You will find that the leads are inserted in the bottom right and left corners of the tester. The dial is turned so that it points to ACV and 250 to test for 120 volts. Leads are inserted into the outlet and the tester should display 120-125 volts approximately or the midway point on the display. I would find the manual first, read and understand it prior to using it. Electricty is dangerious. **Q: Could I use the standard leads from another meter on this unit⁷** A: If you don't have a direct fit, it should be possible to splice into the plugs that come with this unit. Seems to me that the leads for the analog meters are alike, but I don't know about digital meters. Good luck. **Q: What gauge are the wires?** A: Here is all the info I can find on it....
