GVDA Digital Clamp Meter GD166/168 GVDA GD168B Digital Clamp Meter

GVDA GD168B Digital Clamp Meter6000-Count True RMS AC/DC Clamp Multimeter with Inrush, NCV, Temperature & Smart Auto Mode

The GVDA GD168B is a professional True RMS AC/DC clamp meter designed for comprehensive electrical diagnostics in industrial, automotive, and household environments. Equipped with a 6000-count VA color display, SMART AUTO mode, AC/DC current measurement up to 600A, AC inrush detection, temperature measurement, NCV, continuity, and full-range resistance/capacitance testing, the GD168B offers high accuracy and reliability for technicians and advanced DIY users.

Key Features

• True RMS measurement: accurate readings for non-linear and distorted waveforms.
• 6000-count VA color LCD: bright, high-contrast display with automatic unit recognition.
• AC/DC voltage & current measurement: 600mV–600V and 60A/600A (both AC & DC supported).
• SMART AUTO mode: automatically identifies voltage, resistance, continuity, and signal type.
• NCV non-contact voltage detection: quick detection of live electrical fields.
• Live wire detection: ""--L"" for low voltage, ""--H"" for high voltage with buzzer + LED.
• DCA Zero function: enables precise DC current calibration (GD168B-specific).
• Inrush current measurement: captures startup surges in motors and inductive loads (60A / 600A).
• Frequency, duty cycle, resistance, capacitance, temperature: wide multifunction capability.
• MAX/MIN capture: record measurement extremes for diagnostics.
• Backlight & flashlight: supports operation in dark working environments.
• Automatic calibration at startup: displays “CAL” for self-adjustment.
• Clamp opening: 36 mm, suitable for thick cables.
• Safety indicators: over-range “OL”, low battery, and polarity “–”.
