With long leads and robust accessories, reliable readings are achievable even in demanding environments.

User-Friendly Features for Professionals

Engineered for practicality, this instrument features a large backlit LCD for clear visibility, data hold for convenient referencing, and an auto power-off function to conserve battery. Its portable design, supplied case, and over 15-meter test leads offer field-ready convenience. Overload protection, insulation resistance, and accurate three- or two-wire measurement methods ensure both safety and performance.

FAQ's of Metravi ERT-1502 Digital Resistance Earth Tester:

Q: How is the Metravi ERT-1502 used to measure earth resistance?

A: The tester employs either the three-terminal or two-terminal method to measure earth resistance. Users connect the supplied test leads and auxiliary earth rods as indicated in the manual, select the desired range, and read the results on the large LCD display. Data hold and backlight functions enhance usability in diverse environments.

Q: What are the primary applications of this earth tester?

A: This device is ideal for measuring earth resistance and soil resistivity, ensuring the safety and efficiency of grounding systems in electrical installations, substations, and construction sites. It is widely used by electrical engineers, maintenance professionals, and field technicians.

Q: When should I use the three-terminal method versus the two-terminal method?

A: The three-terminal method is recommended for standard earth resistance measurements as it provides higher accuracy by compensating for auxiliary electrode resistance. The two-terminal method can be used for quick checks or where auxiliary earth rods cannot be adequately installed.

Q: Where can the ERT-1502 be used effectively?

A: Due to its robust construction and conformity to IEC61010 safety requirements, the ERT-1502 is suitable for both indoor and outdoor use. Its operational temperature ranges from 0C to 40C, and it can be stored between -20C to 60C, making it adaptable for various environments across India.

Q: What safety features does this earth tester have?

A: The instrument offers overload protection, a robust insulation resistance rating (20M at 500V DC), and a low battery warning indicator. It is designed according to IEC61010 safety standards, ensuring user and equipment safety during testing.

Q: How long does the battery last and how do I know when to replace it?

A: The tester operates on six 1.5V AA batteries, providing power for at least 1,000 tests. A low battery indicator on the LCD alerts you when replacement is necessary, ensuring uninterrupted operation.

Q: What benefits does the data hold and auto power-off offer?

A: The data hold feature allows users to freeze measurements for easier recording, while the auto power-off conserves battery life by turning off the device when inactive, both of which enhance efficiency during field operations.
