Catu Earth & Ground Resistance Tester


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.
