Kyoritsu KEW 4300 Simplified Earth Tester
The Kyoritsu KEW 4300 is a two-pole simplified earth resistance tester with auto-ranging 200 and 2000 ohm scales, a live circuit warning above 30V, and an automatic LED that lights the test point in low ambient light, making it quick to use on distribution lines and appliances.Overview
The Kyoritsu KEW 4300 is a simplified, two-pole earth resistance tester designed for fast checks on distribution lines and electrical appliances. It also measures AC and DC voltage, giving technicians a compact, single-handed instrument for routine earthing verification.
Key Features
- Two-pole method earth resistance measurement with 200 and 2000 ohm auto-ranging scales
- Measures AC and DC voltage, with true RMS values for AC readings
- Warning buzzer triggers when resistance reads 100 ohms or less
- LED lights up when a large earth voltage is detected and warns of live circuits above 30V
- Automatic LED illuminates the measurement point and adjusts to ambient brightness
- Small 2 mA maximum test current will not trip an RCD during testing
Specifications
- Measurement Range: 200/2000 Ohm (auto-ranging, 2-pole method)
- Test Current: 2 mA max (RCD-safe)
- Live Circuit Warning: Triggers at 30V or higher
- Weight: 0.1 kg
- Color: Black
- Country of Origin: Japan

Frequently Asked Questions
When is a simplified two-pole earth tester sufficient instead of a four-point model?
Simplified testers like the 4300 work well for routine checks on small installation earths, appliances, and distribution outlets; larger installations require four-point fall-of-potential testing.
How does auto-ranging on 200 and 2000 ohm scales speed up field testing?
Auto-ranging eliminates manual selection errors and scale switching, reducing test time and allowing technicians to take measurements faster across distribution lines and multiple fixtures.
Why is a live circuit warning above 30V important for technician safety?
The warning alerts technicians to dangerous voltage before they clip the probe, preventing accidental contact with live circuits and reducing electrical injury risk.
How does the automatic LED illumination improve measurements in poor lighting?
The LED highlights the test point in dark areas (basements, cable ducts, outdoor nighttime inspections), making it easy to see where connections are made and improving measurement accuracy.
Is the 4300 practical for rapid compliance checks across an office building?
Yes, quick auto-ranging and simple two-point operation make the 4300 ideal for fast compliance surveys on many distribution outlets and appliance earths in commercial facilities.
Can this tester identify poor earth connections on older electrical installations?
Yes, high readings on the 2000 Ω scale detect corroded or loose connections typical of aging installations, helping maintenance teams prioritize upgrades.
