GVDA Digital Clamp Meter GD166/168 GVDA GD166B Digital Clamp Meter

GVDA GD166B Digital Clamp Meter6000-Count True RMS AC/DC Clamp Multimeter with Inrush, NCV, Temperature & Smart Auto Mode

The GVDA GD166B is a True RMS intelligent clamp meter designed for comprehensive AC/DC electrical diagnostics. With a 6000-count VA-color display, SMART AUTO mode, AC/DC current measurement up to 600A, non-contact voltage detection, temperature measurement, and extended multifunction support, it is ideal for electricians, technicians, automotive work, and advanced DIY users requiring professional accuracy and safety.

Key Features

• True RMS measurement: ensures accurate readings for both linear and non-linear loads.
• 6000-count VA-color LCD display: high-visibility interface with analog bar graph for dynamic signal viewing.
• AC/DC voltage & current measurement: supports 600mV–600V and 60A/600A ranges.
• SMART AUTO mode: automatically identifies AC/DC voltage, resistance, continuity, and signal type.
• NCV non-contact voltage detection: fast live-wire identification with LED indication.
• Live wire detection: visual and audible indication (L/H levels shown on display).
• DCA Zero function: precise DC current calibration (exclusive to GD166B).
• Inrush current measurement: captures motor and inductive-load startup surges (60A / 600A).
• Frequency, duty cycle, resistance, capacitance, temperature: wide multifunction coverage.
• MAX/MIN recording: captures signal extremes for diagnostics.
• Backlight & flashlight: supports work in dark environments.
• Automatic calibration at startup: displays “CAL” during initialization.
• Clamp opening: 36 mm for thick cables.
• Safety indicators: over-range “OL”, low battery symbol, and polarity “–”.
