The cable length makes it easy to check distant circuits such as brake lights and trailer terminal connections. The Multi-Probe Ultra comes with a 23’ cable to connect to the vehicle battery and move around cars, trucks, boats, ATVs and more. An AC meter displays peak-to-peak, pulse width, duty cycle, frequency and TRMS simultaneously to keep techs in the know about the job at hand. Single-function buttons speed scrolling up and down, muting, turning the light on and off and powering a circuit. Data is displayed by unique color for easy recall of the mode in use – purple indicates AC voltage, orange DC voltage, yellow amperage and white represents ohms. ![]() The large, rear-facing LCD navigation screen on the Multi-Probe is easy to read, even in tight spaces, with a color-coded menu. “Our advanced multi-probe tester combines circuit tester functions with a multimeter, so if the vehicle or equipment you’re testing has an electrical problem, this tool can locate it.” “Tracking down an electrical problem without the right equipment can consume much of a technician’s day,” says Dave Brekke, Snap-on product manager. Technicians can test AC and DC voltage, resistance and amperage. The new EECT900 Multi-Probe Ultra from Snap-on features both a circuit tester and digital multimeter in one convenient handheld device.
