Kyoritsu 4200 Earth Clamp Tester

Description

The Kyoritsu 4200 is a digital earth clamp tester designed for measuring earth resistance in multi-earthed systems without requiring auxiliary earth spikes. It also measures AC current and features True RMS for accurate readings, even with distorted waveforms.

Key Features

• Clamp-on measurement: Provides a non-invasive way to measure earth resistance by clamping around the conductor.
• Earth resistance measurement: Measures earth resistance from 0.05\(\Omega \) to 1500\(\Omega \).
• AC current measurement: Offers True RMS readings for AC current, including leakage and phase current, ranging from 0.1 mA to 30.0 A.
• Noise check function: Detects interference currents that can affect resistance measurements and displays a "NOISE" warning on the LCD.
• Data memory: Can save and recall up to 100 measurement data points.
• Backlight: A backlit display and buttons allow for operation in dimly lit areas.
• Buzzer: Sounds an audible alert when the measured earth resistance is 10\(\Omega \) or less.
• Safety rating: The instrument is compliant with IEC 61010-1 CAT IV 300V, providing a high level of safety.
• Auto power-off: Turns off automatically after approximately 10 minutes of inactivity to conserve battery life.
