Catu DT-155 Multifunction Tester Earth Resistance Measurement

The Catu Electrical installation tester combines all essential functions to control and visualise instantly the quality and conformity of 230 V electrical installations. This tester immediately indicates whether the earth conductor in each of your sockets is connected.

The DT-155 tester enables you to perform the presence of voltage at the terminals of a socket, integrity of the earth circuit, correct polarity the position of the phase and the neutral is indicated. It also uses to choose the correct operation of the ELCB system at the following sensitivities, 30 mA, 100 mA, 300 mA, 500 mA, 650 mA.

• Class I reinforcement insulation

• Operating temperature is between -150C and 450C

• Presence of voltage at the terminals of a socket

• Possible detection of the signal with max network current of 80A

• Operating voltage: 230 V ± 10%

• Frequency: 50 / 60 Hz ± 10%

• Operating temperature: - 15°C to + 45°C

• IP 40 IK03

• Presence of voltage at the terminals of a socket, ensuring the circuit is active and safe to work on.

• Integrity of the earth circuit - detects any faults or disconnections in the earth circuit, ensuring proper grounding and protection against electrical hazards.

• Correct Polarity Check - verifies the correct connection of the phase and neutral conductors, preventing potential hazards from reversed polarity.

• Phase and Neutral Indication: Clearly indicates the position of the phase and neutral conductors for quick and easy identification.

• RCD System Check - tests the proper operation of residual current devices (RCDs) at five different sensitivities: 10, 30, 300, 500, and 650 mA. RCDs are crucial for protecting against electrical shock hazards.

Industrial Settings: Industrial electricians can utilise the DT-155 to perform regular safety checks on their installations, maintaining a safe and compliant workplace.

Maintenance Procedures: Maintenance professionals can incorporate the DT-155 into their maintenance plans, ensuring the safety of electrical installations throughout their lifespan.
