FAQ's of Metravi CET-02 Clamp-On Earth Ground Resistance Tester:

Q: How do I use the Metravi CET-02 Clamp-On Earth Ground Resistance Tester?

A: To use the CET-02, simply power on the instrument, clamp the jaws around the earth conductor or rod you wish to test, and read the resistance or leakage current value on the LCD display. There's no need to disconnect the ground electrode, making testing quick and straightforward.

Q: What types of measurements can the CET-02 perform?

A: The instrument measures earth ground resistance (from 0.01 to 1200) and AC leakage current (from 0.1mA to 30A) in ground rods, plates, and earth loops, providing precise results for both safety and efficiency assessments.

Q: Where is the CET-02 typically used?

A: This tester is widely used in industrial, commercial, and utility settings across India, especially for routine site inspections, electrical safety audits, and preventive maintenance of grounding systems.

Q: What is the process for storing and recalling data?

A: The CET-02 can store up to 99 measurement results. After taking a reading, you can save it to memory. Stored data can later be recalled directly on the LCD display, facilitating record-keeping and analysis.

Q: When should I replace the batteries in the device?

A: The tester uses four 1.5V AA alkaline batteries, supporting approximately 1200 measurements. Replace the batteries once the low battery indicator appears on the display to ensure continued reliable operation.

Q: What are the benefits of using a clamp-on tester over traditional earth resistance testers?

A: Clamp-on testers like the CET-02 enhance safety and efficiency, as they eliminate the need to disconnect ground electrodes or use auxiliary rods. This allows for non-intrusive, rapid, and accurate testing in live systems.

Q: How accurate is the CET-02 Clamp-On Earth Ground Resistance Tester?

A: The device provides a high accuracy of 1%0.01 for resistance and 2%0.05mA for current, ensuring reliable measurements suitable for professional applications.
