Gardner Bender GMT-318 Analog Multimeter, 6 Function, 14 Range, AC / DC Volt, 500V Product Description This multifunctional analog multimeter was designed for the homeowner, hobbyist, or professional needing to make electrical and electronic equipment measurements. 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.
