ABOUT DY4100A/B：
2-in-1 Ground and Earth Tester: The DY-4100B is a versatile 2-lead/3-lead/4-lead resistance tester, equipped with microprocessor control. It measures both DC and AC voltage with an output of approximately 50 Vrms or less, ideal for testing grounding resistance of distribution cables in agricultural equipment, internal wiring, electrical machines, etc.
Adjustable Resistance Measurement: This insulation tester features 4 adjustable resistance levels (0-2Ω, 0-20Ω, 0-200Ω, 0-2000Ω) to meet the needs of different scenarios. The ground tester also offers 4 level adjustments for versatile application.
Night Vision LCD and Protective Casing: The digital megaohmmeter boasts a high-resolution large display for clear readings. Its robust casing is drop-resistant, dustproof, and moisture-proof, providing excellent protection for the instrument.
Automatic Safety System: To prevent battery over-discharge, the device automatically powers off after about 5 minutes of inactivity. If the "Test" button is pressed without connecting the test lead, numbers other than "OL" may appear, especially in the range over 200Ω, which is not indicative of a malfunction.
Usage Tips: Ensure the range switch is set correctly before testing. After use, switch to OFF and disconnect the test leads. Operate in environments with temperatures from -10°C to 50°C and altitudes up to 2000m. Avoid high temperature, humidity, or wet locations.
