The Triplett 1201 Compact AC/DC Digital Multimeter is a 3 1/2 digit, handheld digital multimeter with automatic power off and a backlit LCD display. Using a Large Scale Integration (LSI) integrated circuit, the multimeter is designed for stability and accuracy. The resilient outer molded cover provides additional protection from the occasional fall, and the threaded probe tips and screw on insulated clips provide for secure, hands-off measurements. The meter can measure AC and DC voltage, DC current, resistance, temperature, and forward diode voltage drop. It can also perform an audible continuity test, and test both 1.5V and 9V batteries. With an industry standard CAT III design, it provides resistance to damage from transient overvoltages in many demanding settings. The Model 1201 is well suited for a variety of commercial and residential applications, including security, home theater, electrical, HVAC installations and more.
