KYORITSU KEW 6516 Multi Function Installation Tester
The KYORITSU KEW 6516/6516BT is a robust, all‑in‑one installation tester designed for electrical professionals. Housed in a durable, impact‑resistant casing with an ergonomic grip, it delivers eight key test functions continuity, insulation resistance, loop impedance (including high‑current and Anti‑Trip Technology modes), prospective short‑circuit current (PSC/PFC), RCD, voltage, phase rotation, and earth resistance without changing instruments. Its large, color LCD presents all live measurements at a glance, while the HELP key provides on‑screen wiring diagrams for immediate guidance.
The built‑in LOCKDOWN switch and optional remote probe enable hands‑free testing, improving safety and efficiency on site. Anti‑Trip Technology (ATT) allows loop tests at ≤15 mA to bypass RCDs rated ≥30 mA, avoiding unwanted trips and speeding up inspections. Connectivity options include a USB adapter (Model 8212USB) for PC‑based test reporting and, on the BT version, Bluetooth® communication to tablets or smartphones via the KEW Smart app. Powered by eight AA batteries, the KEW 6516 offers up to 3 500 RCD tests on a single set, and features auto‑power‑off and internal memory for up to 1 000 readings.
With full compliance to IEC 61557 and safety ratings to CAT III 600 V/CAT IV 300 V, it is ideal for commissioning, maintenance, and troubleshooting in residential, commercial, and industrial installations.
Features:
- Eight Functions in One: Continuity, insulation, loop impedance (high‑current & ATT), PSC/PFC, RCD, voltage, phase rotation, earth.
- Anti‑Trip Technology (ATT): Loop tests without tripping RCDs ≥30 mA using 2‑ or 3‑wire methods.
- High‑Resolution Loop: 0.001 Ω measurement at 25 A for precision near transformer.
- Hands‑Free Testing: Remote probe and LOCKDOWN switch for extended measurements.
- HELP Key: On‑screen connection diagrams tailored to each test.
- Auto‑Discharge: Insulation test auto‑discharge prevents stored charge hazards.
- Battery & Fuse Protection: 0.5 A HRC fuse in continuity circuit; auto‑power‑off to conserve AA batteries.
- Memory & Connectivity: Internal storage (1 000 readings), USB (8212USB), Bluetooth® (BT version) for data transfer.
