EARTH CLAMP TESTER - KEW 4202
KYORITSU 4202 Digital Earth Clamp Tester
The KYORITSU 4202 digital earth clamp tester is a high-precision instrument designed to measure ground resistance without disconnecting the earth system. The KYORITSU 4202 digital earth clamp tester provides reliable readings for electricians, engineers, and maintenance personnel in industrial, commercial, and residential environments.
Overview
The KYORITSU 4202 digital earth clamp tester allows accurate ground resistance measurement without the need to disconnect the earth system. Its portable design and high-precision capability make it ideal for field inspections, maintenance, and electrical safety audits. This tester is durable, easy to use, and compatible with a wide range of industrial and commercial applications, ensuring efficient and safe measurements every time.
Key Features:
- Wide Measuring Range: Measures earth resistance from 0.05Ω to 1500Ω, suitable for multi-earthing systems.
- True RMS Measurement: Provides leakage and phase current readings from 0.1mA to 30.0A for comprehensive analysis.
- Noise Immunity: The filter function helps reduce the impact of electrical noise, with a noise mark indicating excessive interference.
- Memory Function: Stores up to 100 data sets for later retrieval and analysis.
- Bluetooth® Connectivity: Easily syncs with the "KEW smart 4202" app available on the Google Play Store, enabling convenient data transfer to Android devices.
- Over-Range Indication: Displays "OL" when the input exceeds the upper limit of the measuring range.
- Auto Power Off: Automatically powers off the device after 10 minutes of inactivity to conserve battery life.
