KYORITSU KEW 6516 Multifunction Installation Tester: Low-Voltage Installation Testing in One Instrument

Overview

The KEW 6516 is a KYORITSU multifunction installation tester that performs, in one instrument, the insulation, loop impedance, RCD, earth, continuity, voltage and phase rotation tests commonly used to inspect low-voltage electrical installations. The HELP screen shows the wiring for the selected function, and the Zs / Ra Limit function gives a PASS / FAIL judgment against set values. This model transfers data via USB; for wireless transfer, the KEW 6516BT is available.

Key Specifications

• Insulation resistance: 100 / 250 / 500 / 1000 V, automatic discharge after testing
• Loop impedance: L-PE / L-N; ATT (2-wire and 3-wire) measures L-PE without tripping the RCD; high-current 2 Ω range with 0.001 Ω resolution; PSC / PFC calculation
• RCD: Type AC, A, F, B (general and time-delayed), EV and variable; ×1/2, ×1, ×5, Ramp, Auto, Uc
• Earth and continuity: Earth 20.00 / 200.0 / 2000 Ω, 2-wire and 3-wire; continuity at 200 mA or 15 mA
• Voltage and phase rotation: Voltage 2–600 V, 45–65 Hz; phase rotation 48–600 V
• Other: SPD (varistor type) operating voltage; PAT insulation and protective conductor resistance
• Standards and protection: IEC 61010-1 CAT IV 300 V / CAT III 600 V; IEC 61557-1, 2, 3, 4, 5, 6, 7, 10; IP40
• Power and weight: 8 × AA; 136 × 235 × 114 mm, approx. 1350 g (including batteries)

Applications

• Completion and periodic inspection of low-voltage electrical installations.
• RCD testing of EV charging equipment (EV type 6 mA).
