On-line Grounding Resistance Monitor

The ETCR ETCR2800N is an on-line tester designed for continuous monitoring of grounding system resistance. It serves electricians and facility engineers who need permanent insight into earth connection status without interrupting the grounding circuit. The instrument measures from .010 up to 200 ohms and is intended for integration into fixed installations or secondary development projects.

Installation and Common Issues

The unit is built to be embedded inside another enclosure, which simplifies permanent mounting but requires mechanical design work by the integrator. Wiring the RS485 link demands correct MODBUS-RTU address and baud-rate configuration; mis-set parameters are the typical cause of communication failure. If the GPRS option is used, adequate cellular signal at the mounting location must be verified beforehand.

Pre-Order Compatibility Checks

Confirm that the grounding conductor can physically pass through the detector perforation without altering the existing lightning protection path. Decide whether RS485 wired networking or GPRS wireless reporting matches the site infrastructure and budget. Ensure the host system can poll MODBUS-RTU registers or receive GPRS data packets for real-time monitoring and remote alarm functions.

Questions about this item

How can I confirm the ETCR2800N is monitoring correctly after installation?

The unit performs real-time, non-contact measurement as the grounding wire passes through its perforation, so a live reading between .010 and 200 Ω on the display or via the network confirms normal operation.

What comes in the box and what must I source separately?

The package contains one ETCR2800N tester; any RS485 or GPRS communication cabling, mounting hardware or integration accessories for secondary development are not included and must be purchased separately.

Should I choose the RS485 or GPRS version for my network?

Select RS485 when a wired MODBUS-RTU link to a local SCADA or PLC is preferred, and choose GPRS when wireless remote monitoring over a cellular network is required.
