KEW5050 is a leakage current meter that can measure leakage current (Io) and resistive leakage current (Ior).
The Kyoritsu KEW5050 is a leakage current logger designed to measure resistive leakage current (Ior) in various wiring configurations, including single-phase and three-phase systems. The device features a large LCD display, multiple keys for navigation, and supports data recording to an SD card for later analysis. It is equipped with specific clamp sensors and voltage test leads to ensure safe and accurate measurements in different electrical environments.
The manual covers the complete user experience, from unpacking and initial setup to advanced settings and data transfer to a PC. It details how to attach markers, install batteries, and connect the device to the circuit under test. Additionally, it explains how to configure event settings for upper and lower threshold values, view vector diagrams, and utilize the included PC software for data analysis and troubleshooting.
| Measurement Category | CAT III 300 V |
|---|---|
| Reference Voltage Input Rating | CAT IV 300 V, CAT III 600 V |
| AC Adapter Frequency | 50/60Hz |
| Included Battery Type | Alkaline size AA battery (LR6) |
The Ior leakage clamp sensors (KEW8177/8178) are rated to CAT III 300 V.
The reference voltage input terminals are rated to CAT IV 300 V, but the clamp sensors limit the sensor side to CAT III 300 V.
The device requires 6 pcs of Alkaline size AA batteries (LR6).
