XinTester XT5910 RCD & Loop Resistance Tester
A faulty Residual Current Device (RCD/GFCI) can lead to catastrophic electrical shocks and electrical fire hazards in industrial installations. The XinTester XT5910 provides accredited testing of trip currents, trip response times, loop impedance, and fault touch voltages. Learn more about our grounding and impedance instruments in the Resistance Meter section.
Multi-Gear RCD Verification
Supports selectable multipliers (×1/2, ×1, ×5) alongside ramping test modes. Operators can verify whether a 30mA breaker trips within the mandatory 300ms limit at ×1, or under 40ms during severe ×5 surge events.
Contact Voltage & Phase Angle Control
Pre-checks dangerous contact voltage (Uc up to 50V) prior to energizing. Selectable 0° and 180° test phases ensure that asymmetrical waveform tripping characteristics comply strictly with IEC 61557 requirements.


Safety Compliance & In-Box Equipment
Compliant with CAT III 600V electrical isolation. Comes complete with a 3-wire test lead set, standard wall socket testing lead, crocodile clips, USB data cable, PC software, and hard carrying case.

FAQs
Q1: Can I export my test results to a computer?
Answer: Yes, you absolutely can. The device includes a reliable USB 2.0 interface. Specifically, you can easily upload up to 1000 stored datasets directly to your PC.
Q2: What current test gears are available on this model?
Answer: It provides multiple fast and slow current gears. Specifically, these include 10mA, 30mA, 100mA, 300mA, and 500mA. Therefore, it handles diverse electrical diagnostic scenarios efficiently.
Q3: Does the screen work well in poorly lit environments?
Answer: It works exceptionally well in the dark. The extra-large HD display features a bright backlight. Consequently, you can read measurements clearly inside dark basements or electrical cabinets.
Q4: Is the exterior durable enough for industrial fieldwork?
Answer: Yes, it is incredibly durable. The protective sleeve utilizes industrial-grade rubber. As a result, it provides excellent anti-fall protection and resists daily mechanical wear completely.
