Multifunctional electrical tester built for accurate, everyday troubleshooting and measurement Key benefits Consolidates many test functions into one instrument so you can diagnose electrical issues faster without swapping tools. Clear, high-contrast VA color reverse display and touch sensor make readings easy to see and operate in different environments. NCV non-contact detection and bright front light improve safety and speed when locating live conductors or working in low light. What it measures and how it helps AC/DC voltage and AC/DC current: test household, automotive, and industrial circuits for correct voltage and current without separate meters. Resistance, capacitance, frequency, duty cycle: verify components and signal quality for repairs and maintenance. Temperature: capture thermal readings for HVAC and equipment diagnostics (sensor-equipped). Diode and buzzer: check semiconductor components and continuity fast. Zero fire line detection: identify live/neutral orientation to reduce wiring errors. Data hold: freeze readings on the 6000-count display for safer, easier viewing. Display and controls Intelligent sensor touch screen for responsive, intuitive operation. VA color reverse LCD for high contrast and visibility in different lighting. 6000-count maximum display with data hold to read values clearly in the field. Safety and practical features NCV (Non-Contact Voltage) sensor: detects live conductors without contact; alarm rate increases and the flashlight flashes red as you get closer to the power source to help you pinpoint live wires quickly. Built-in front light: illuminates measurement points in dark work areas so you can see connections and measurement points clearly. Practical use scenarios 1. Home electrical troubleshooting: verify outlet polarity and live circuits, check continuity, and measure voltages safely with NCV detection before working on wiring. 2. Appliance and HVAC service: measure temperature, capacitance, and frequency for motors, capacitors, and controls while using the front light to see terminals. 3. Automotive and battery diagnostics: test DC voltage and current, diodes, and resistance for charging systems, starters, and sensors. Notes on compatibility and performance Supports both AC and DC measurement modes across voltage and current ranges (as listed). 6000-count VA color reverse LCD provides precise readings and good visibility in varied light conditions. Touch-screen operation and compact form factor simplify field use and reduce the need for multiple instruments. This tester is designed to combine multiple measurement functions, non-contact safety features, and a readable display to streamline electrical diagnosis and repair across residential, automotive, and light industrial applications.
