The Gardner Bender GMT-318 Analog Multimeter is a versatile and easy-to-use tool designed for electrical and electronic equipment measurements. With its color-coded analog display, the device offers 6 functions on 14 ranges for quick, accurate readings, including AC and DC voltage, DC current, resistance and dB decibels. It can also measure common 1.5V–9V household batteries.

Unit tests AC and DC voltage of 10-50-250 and 500 Volts, DC Current 250 mA, up to 50K (Rx1, Rx10, Rx100) of Resistance (Ohms), -20 to +56 dB Decibels on AC voltage ranges, 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.
