Kyoritsu 4202 Earth Clamp Tester

Description

The Kyoritsu KEW 4202 is a digital earth clamp tester that, in addition to measuring earth resistance and AC current, includes a Bluetooth communication function to transfer and save measurement data on an Android device. This provides significant advantages for remote monitoring and data management.

Key Features

• Bluetooth communication: Allows real-time measurements to be transferred, displayed, and saved on a paired Android device using the "KEW Smart 4202" application.
• GPS data collection: Saved data includes not only the measurement values but also the date, time, and GPS location where the measurement was taken. This allows for easy mapping of measurement locations.
• Comparator function: Using the Android app, you can set preset values and use the comparator function to be notified when measurements are outside of the acceptable range.
• Clamp-on measurement: Provides a non-invasive way to measure earth resistance from 0.05\(\Omega \) to 1500\(\Omega \) in multi-earthed systems without needing auxiliary earth spikes.
• True RMS: Provides accurate AC current readings, including leakage and phase current, even with distorted waveforms.
• Noise check: Detects interference currents that can affect resistance measurements and displays a "NOISE" warning.
• Data memory: Can save up to 100 data points internally.
• Backlight: A backlit display and buttons allow for operation in dimly lit areas.Safety rating: The instrument is compliant with IEC 61010-1 CAT IV 300V.
