KYORITSU LOOP/PFC/PSC TESTER MODEL 4118A

Description

Precision and Reliability in Loop Testing

In the complex field of electrical diagnostics, the accuracy and reliability of your tools are non-negotiable. This instrument is at the forefront of this, designed with a custom microprocessor to ensure the highest levels of performance. Its core function is to perform loop impedance and prospective short circuit current (PSC) measurements with exceptional precision. The device’s intelligent design eliminates common problems associated with traditional testers, making it an indispensable asset for professionals. The large, custom digital display provides clear and easy-to-read data, allowing technicians to quickly and confidently assess the safety of an electrical installation. This is a tool built for accuracy, reliability, and ease of use in the demanding world of electrical work.

Low-Current Loop Testing for Efficiency

A significant challenge in loop testing is the risk of tripping a sensitive Residual Current Device (RCD). This tester solves that problem with a specialized 15mA LOOP measurement function. This low test current is carefully calibrated to ensure that it will not cause RCDs to trip, even those with the lowest nominal differential current of 30mA. This “no-trip” capability is a major time-saver for professionals, preventing unnecessary power outages and allowing them to conduct tests on energized circuits without disrupting the power supply. This intelligent feature is a testament to the device’s thoughtful engineering, making it a highly efficient and practical tool for modern electrical diagnostics.

Comprehensive Diagnostics and Safety Features

Beyond its core function, this tester is packed with features that enhance both its diagnostic capabilities and user safety. The inclusion of 3 LEDs provides an immediate and clear visual check of the correct wiring status of the socket, including a crucial warning for reversed phase and neutral wiring. This instant feedback is a vital safety check before any testing begins. The device can also measure low loop resistances with a high resolution of 0.01Ω, providing detailed and accurate data that is essential for a thorough safety assessment. A significant safety feature is the automatic lock-out if the test resistor overheats, which protects both the user and the instrument from potential damage. This combination of advanced diagnostics and robust safety features makes the tester a highly reliable partner in the field.

Specialized Applications for Electrical Professionals

The versatility and precision of this instrument make it an essential tool for a wide range of applications. For electricians and field service technicians, it is the perfect tool for verifying the safety of new and existing electrical installations. The no-trip loop testing is particularly useful in environments with sensitive equipment, such as data centers or hospitals. The ability to directly read Prospective Short Circuit Current (PSC) is invaluable for electrical inspectors and engineers who need to confirm that a circuit’s protective devices are correctly rated. It’s also a great tool for maintenance technicians who need to perform routine safety checks on circuits to ensure ongoing compliance and reliability.

Built to Withstand the Toughest Environments

Durability is a key consideration for any tool used in the field, and this tester is built to last. It is designed to an IP54 rating, which provides robust protection against both dust ingress and splashing water from any direction. This makes it a reliable instrument for use in a variety of challenging environments, such as dusty construction sites, workshops, or damp outdoor settings. The rugged construction ensures that the device can withstand the rigors of daily use without compromising its performance or accuracy. This commitment to durability guarantees that the tester will be a long-lasting and reliable partner for professionals.

The Importance of Precise Loop Measurements

Loop impedance is a fundamental safety parameter in any electrical system. An accurate measurement is crucial for ensuring that a fault current will be large enough to trip a circuit breaker or blow a fuse quickly, thereby protecting people from electric shock and preventing fires. This tester’s high-resolution measurement of loop resistance and its ability to provide a direct reading of PSC give professionals the precise data they need to make informed decisions about an installation’s safety. This level of detail and accuracy is what sets this instrument apart and provides the confidence required for safety-critical work.

A User-Friendly Interface for Professionals

Despite its advanced capabilities, the tester is designed to be highly intuitive and user-friendly. The large digital display provides a clear and uncluttered interface, and the LEDs offer a simple, immediate visual status of the wiring. This combination of a detailed display and quick visual indicators allows for rapid and efficient diagnostics. The device’s thoughtful design, which includes features like the automatic lock-out for overheating, ensures that the user can focus on the task at hand without worrying about the instrument’s performance or safety. It’s a perfect blend of high-end technology and practical, real-world usability.
