Overview
The GSCETE CM520A is a high-precision digital clamp meter designed to make electrical troubleshooting faster and safer. Unlike manual meters, the CM520A features Auto-Ranging, meaning you don’t have to guess the correct scale—the meter does it for you. It also includes an NCV (Non-Contact Voltage) sensor that lets you detect live wires behind walls or inside panels without touching a single copper strand.
Key Features
Auto-Ranging Convenience: Simply select the function (Voltage, Current, or Resistance), and the meter automatically selects the best resolution.
NCV Detection: Integrated non-contact voltage sensor with an audible alarm and LED indicator for maximum safety.
True AC Current Measurement: Accurate induction clamping for AC current up to 600A.
Backlit LCD Display: Clear, high-contrast screen makes it easy to read values in dark attics or basement panels.
Temperature Testing: Comes with a K-type thermocouple to measure heat in motors, HVAC vents, or electrical components.
