One probe. Multiple ways to diagnose electrical problems.
Voltage, polarity & continuity
See circuit voltage on the LCD while red and green LEDs quickly identify polarity, and check continuity in wires and components.
Power & ground at the tip
Use the power switch to apply battery positive or ground through the probe tip to activate components and verify operation. The manual specifically shows applications including lights, motors, fuel pumps, solenoids, relays, and other electrical components.
Five diagnostic modes
Go beyond basic voltage testing with five modes for standard circuit testing, positive and negative peak capture, peak-to-peak measurement, and adjustable peak-detection thresholds.
