Description
Product Overview
The ZHOUCE ZC-501 Digital Insulation Resistance Tester is engineered for precision, durability, and ease of use in demanding electrical maintenance environments. It offers an ultra‑wide measurement range from 0.06 MΩ to 50 GΩ, allowing technicians to detect both minute insulation defects and high‑resistance conditions with confidence. The device features an automatic ranging system that selects the optimal measurement scale in real time, delivering 2000‑count resolution and a resolution of 0.01 MΩ. A built‑in 2 V‑750 V AC/DC voltmeter adds versatility, enabling voltage verification alongside resistance testing. The LCD screen displays clear numeric readouts and stores up to 500 test records, facilitating traceability and trend analysis. Constructed from a rugged ABS housing, the tester meets IP54 protection standards, resisting dust and splashes while maintaining a lightweight profile of approximately 2 lb (0.9 kg). The ergonomic design includes a rubber‑grip handle, a rotary selector for test voltage levels, and a protective cover for the probe sockets, ensuring safe operation in cramped or elevated workspaces.
Usage
The ZC‑501 excels in a variety of field and shop‑floor scenarios. Electrical contractors use it to verify insulation integrity on low‑voltage control circuits, medium‑voltage motor windings, and high‑voltage transformer windings. Facility maintenance teams rely on the tester for routine preventive inspections of HVAC systems, generators, and UPS units, where early detection of insulation degradation can prevent costly downtime. In industrial plants, the device supports compliance testing for IEC 60364 and NFPA 70E standards, providing documented evidence of safe insulation levels. Its compact size and battery‑operated design (9 V rechargeable) allow technicians to carry it on ladders, in confined conduit spaces, or aboard service vehicles. The integrated voltmeter simplifies troubleshooting by enabling simultaneous voltage checks without swapping tools, reducing the risk of accidental contact with live circuits. Data stored on the LCD can be transferred manually to maintenance logs, supporting root‑cause analysis and regulatory reporting.

FAQ
What is the accuracy of the insulation resistance measurement?
The ZC‑501 provides a measurement accuracy of ±1 % of reading plus one least significant digit across the entire 0.06 MΩ‑50 GΩ range, which meets the requirements of most industrial and commercial inspection standards.
Can the device be used on both AC and DC circuits?
Yes. The tester supplies selectable AC or DC test voltage, and the built‑in voltmeter also measures AC and DC line voltages, making it suitable for a wide variety of electrical systems.
How is the data stored and retrieved from the LCD?
Each test result is automatically saved in the internal memory and displayed with a timestamp. Users can scroll through stored entries using the navigation keys and manually record the values in maintenance reports. Optional USB data logger accessories allow direct export to a computer.
What safety certifications does the ZC‑501 have?
The tester complies with IEC 61010‑1 safety standards, carries CE marking, and meets UL 61010‑1 requirements for handheld electrical test equipment.
Is the battery replaceable or rechargeable?
The unit uses a built‑in 9 V rechargeable lithium‑ion battery that provides up to 12 hours of continuous operation. The battery can be recharged via the included USB‑C port, and a spare battery pack is available as an optional accessory.
