The Catu earth and ground resistance tester measure a 1.999kΩ absolute maximum resistance and is having a CAT III safety category. This tester is used to ensure proper operation of the earthing system. It emits a sound signal for continuity checks and directly displays the value on the LED screen. It is also used to measure the electrical characteristics of a system. The measurement of the earth resistance, performed by this device, is based on the measurement principle called "fault loop". The measurement is carried out with an accuracy of (+/-3% +1 digit) on pure resistance, range of 0-200 Ω at 23 °C +/-5°C.
Features and Benefits
Available with a touch point on extension cord of 7m and instructions for use, without a case Displays the presence of Voltage and the phase position Measures the earth loop (fault loop) without tripping the circuit breakers: <15 mA Non-slip coating for a better grip Once connected to a properly connected installation, the earth value is displayed instantly on the top of the 4-digit LCD display that can indicate earth resistance values ranging between 0 and 100Ω in blue colour digits (at the 100 Ω threshold recommended by NF C 15-100) and between 101Ω and 1999Ω in red colour digits Operating temperature ranges between -150C and 450C Total autonomy (without battery) Two-way use: 2P + T socket or LV switchboard with cord
Applications
• Measurement of earth resistance. • Highlight phase position and check the presence of earthing connection. • Controls continuity of metal masses (buzzer).
Features
• Quick reading of conformity due to bicolor LCD Display (blue = OK/ red= no conformity). • "Default loop" principle using for earth measurement in TT schema. • Earth measurement with 3 1/2 digits LCD display (from 0 to 1999 Ω). • Accuracy: ± (3% + 1 digit) for pure resistance, range 0 to 200 Ω at 23°C ± 5°C. • Show presence of dangerous voltage (400 V - connection between phases). • Full autonomy: no battery, power supply by plugging on 2P+T outlet.
Composition
