Online earth resistance monitoring
The ETCR ETCR2900 performs continuous on-line monitoring of grounding system resistance, equipotential bonding resistance and earth voltage. It uses precision three-wire or simple two-wire measurement methods with average-value rectification for voltage. A 124×67mm LCD shows readings in real time and the unit can store data automatically to generate reports.
Electrical maintenance teams and facility engineers
Suited for personnel who need permanent, remote surveillance of grounding installations and want MODBUS communication via RS232 or RS485 for network integration. Not intended for users who only require occasional spot checks with a handheld meter or who need a tester without data-logging and alarm functions.
Measurement range 0.010Ω–2000Ω and 600V AC
The single specification that decides suitability is the combined resistance range of 0.010Ω to 2000Ω alongside an AC voltage range up to 600V. If the installation under test falls outside these limits, a different instrument must be selected.
