• True RMS
• Measures voltage drop under 12, 15, and 20-amp loads
• Measures voltage: line, ground-to-neutral, peak, frequency
• Measures hot, neutral, and ground conductorimpedances
• Identifies proper wiring in 3-wire receptacles
• Identifies false (bootleg) grounds
• Tests GFCIs for proper operation

This test instrument "looks behind walls" to identify wiring problems that can lead to personal shock hazards, electrical fires, or equipment performance issues. Incorporates all the branch circuit testing capabilities you need to effectively test and troubleshoot a branch circuit. It can apply a full 12, 15, or 20-amp load to a circuit for voltage drop measurements. This capability helps detect high-resistance points that cause fits for equipment on the line, such as loose connections, corroded sires, bad splices or faulty electrical devices. It also offers important features like True RMS, ground impedance, peak voltage, frequency, GFCI testing, and the capability to identify proper wiring in 3-wire receptacles with a sleek handheld frame and one-touch operation. SureTest® Model 61-165 also tests arc fault circuit interrupter (AFCI) devices to ensure that AFCI breakers protecting the circuit have been installed correctly. Additionally, it checks for a shared neutral condition that leads to AFCI nuisance tripping. Comes with 1-ft. extension cord and carrying case.
