AC Leakage Clamp Meter

HIOKI CM400112 Juni 2020 - The new CM4001 of Hioki is a compact clamp meter that measures everything from AC leakage current to AC load current. Its jaws, which house its current sensor, are shaped so that they can be clamped around wires in confined, complex installations safely and easily to speed up the measurement process. Further, a new comparator function halves the amount of time needed to carry out current leakage checks by alerting users to comparative measurement results with audio and visual cues.

The process of maintaining electrical equipment in buildings and plants includes periodic insulation management. Since current leaks can lead to equipment malfunctions and electric shock, it is essential to locate them quickly. Additionally, in today’s world where electric power is critical to our everyday lives, electricity users demand maintenance methods that do not necessitate power interruptions.

Technicians use leakage clamp meters to measure current quickly and easily simply by clamping them around wires, eliminating the need to shut off the power. Conventional designs have circular jaws to ensure performance, making them difficult to clamp around wires. Furthermore, the recent trend toward compact distribution panels has led to installations whose closely spaced wires sometimes defy measurement with conventionally shaped instruments. As a result, technicians have to spend more time and effort carrying out regular inspections and leakage checks.

Hioki currently offers a lineup of clamp meters with an innovative jaw profile that makes the instruments easier to clamp around wires. Leveraging that technology, the company developed a leakage clamp meter that is even easier to clamp around wires while maintaining the level of performance required in leakage current measurement. The new test tool also features a comparator function that will help customers boost work efficiency by streamlining the leakage check process.

KEY FEATURES

1. Easy-to-clamp jaws for streamlined measurement

Thanks to a jaw profile that slips readily into confined, complex wiring installations, the CM4001 can be clamped around wires safely and easily. This design smooths the measurement process and shortens work times. In doing so, it eases the workload on the technicians who are responsible for managing equipment and increases safety by eliminating the need to pull out wires in order to test them.

2. New comparator function for faster leakage checks

A new comparator function compares a user-set reference value with the indicated value to generate aninspection decision. Since the result is communicated by means of sound and light, users can quickly pinpoint current leaks without needing to look at values on the display. Together, the easy-to-clamp jaw profile and comparator function let customers double work speed compared to conventional designs.

3. Ability to measure everything from leakage current to load current

With accuracy guaranteed from 0.60 mA to 600.0 A, the CM4001 provides a one-stop solution for a range of field measurement needs. The instrument’s 24 mm clamp diameter readily accommodates thick, closely spaced wires and double wires.

4. Wireless Adapter Z3210 with Bluetooth wireless technology for easier post-measurement workflows (option)

When connected to the optional Wireless Adapter Z3210 (available soon), the CM4001 can be paired wirelessly with a tablet or smartphone using Bluetooth. Customers can then use GENNECT Cross, Hioki’s free smartphone app, to review and record measurement results on their smartphone.
