Purpose and user

The ETCR ETCR2800B is a non-contact grounding resistance tester designed for continuous on-line monitoring of earthing systems. It suits maintenance teams and facility engineers who need real-time data without interrupting the grounding path or disconnecting conductors.

Interface limits

The instrument communicates through an RS485 wired link or a GPRS wireless channel, allowing a network to be built for remote supervision. Measurement spans from .010 to 200 ohms, and the built-in sensor is fully sealed to maintain accuracy during long-term field deployment.

Pre-installation checks

Verify that the grounding conductor can pass through the detector perforation and that the installation zone complies with the Exia BT3 Ga explosion-proof rating certified under CE18.2332X. Confirm RS485 cabling or GPRS coverage is available at the mounting location before ordering.

Questions about this item

Should I choose the ETCR2800B if I need to measure very low grounding resistance?

Yes, the ETCR2800B measures from .01 Ω up to 200 Ω, so it covers very low resistance values for grounding systems.

What does the 0.01~200 Ω range mean when the tester is installed on a live grounding system?

It means the ETCR2800B can continuously monitor earth resistance from .01 Ω to 200 Ω without interrupting the lightning protection or normal operation.

How do the RS485 and GPRS interfaces limit the way I collect data from the ETCR2800B?

RS485 provides wired communication while GPRS enables wireless transmission; both let you build a network for real-time remote monitoring of grounding resistance.
