Kyoritsu KEW6516 professional multifunction multimeter for testing electrical installations. METER WITH CALIBRATION Multifunction meter for testing electrical installation with 8 functions: 1. continuity test 2. insulation resistance test 3. short circuit loop impedance measurement (high current measurement, measurement with ATT function) 4. measurement of predicted L-N short-circuit current (PSC) and L-PE fault current (PFC) 5. test of residual current circuit breakers (RCD) 6. voltage measurement 7. phase rotation direction test 8. measurement of grounding resistance Included: - meter in a dedicated plastic case - USB adapter (optical connection) with a mini USB cable [8212-USB]. - 3 test leads with needle type tips and crocodiles [7246/7247] - 1.4m test cable with remote switch [7281] - 2 pins 215x40mm [8041] - 3 cables with lengths of 5m, 10m and 20m for ground resistance testing [7228A] - power cable - calibration certificate - manual - shoulder strap for the meter - CD - case for accessories - capacious bag for the meter and accessories The KEW6516 meter has an Anti Trip Technology (ATT) function, which enables the measurement of short circuit loop impedance without triggering the RCD circuit breaker. Such measurement saves measurement time by eliminating the need to shunt the RCD circuit breaker from the circuit. When using the ATT function, the test is performed with a current of 15mA or less between the phase and protective conductor. (L-PE) The instrument thus makes it possible to measure short-circuit loop impedance without tripping RCD circuit breakers rated at 30mA or more. The ATT function is available for 3-wire (L, PE, N) and 2-wire (L, PE) measurement. The meter does not have Bluetooth communication only an optical connector for data transfer to a PC.
