GD169A Digital Clamp Meter – 1000A AC/DC True RMS, 1000V DC / 750V AC, VFD Mode, Inrush Current, LowZ, NCV, Temperature, Capacitance, Frequency
GD169A True RMS Clamp Meter — 1000A AC/DC Industrial Multimeter with VFD & LowZ
The GD169A is a high-performance True RMS clamp meter designed for professional electrical troubleshooting, industrial maintenance, and HVAC service work. It measures AC/DC current up to 1000A using the clamp jaw and voltage up to 1000V DC or 750V AC with test leads, delivering flexible diagnostics across power systems and equipment.
A large 6000-count HD color LCD with backlight and built-in flashlight improves visibility in panels or dark environments, while smart AUTO measurement and automatic current identification streamline daily workflow. Advanced functions such as VFD voltage/current measurement, inrush current capture, and LowZ mode help diagnose real-world installations including motor drives and long cable runs.
The instrument also supports NCV detection, live wire testing, resistance, capacitance, frequency, duty cycle, temperature measurement, MAX/MIN tracking, and relative measurements. Powered by standard AAA batteries, it provides portable capability for technicians performing complex field diagnostics.
Handles high-current AC/DC diagnostics safely.
VFD mode, inrush capture, and LowZ measurement support.
Automatic detection for faster troubleshooting.
Backlight, flashlight, MAX/MIN, REL and hold features.
