I. Brief Introduction ETCR2000C Multifunction Non-Contact Resistance Online Tester is our company devotes ourselves to Grounding resistance test technical research’s another new high-tech product for more than ten years. Detector adopts weather fastness material manufacture, temperature resistance, cold-resistant, corrosion prevention, fire prevention. Detector’s structure is rigorous and firm, against rain, dustproof, installation and use outdoors. Non-contact measurement, safe and reliable, Ease of installation. Grounding down lead is directly through the detector perforation, Will not affect lightning protection grounding effect and the normal operation of the facilities. Ensure high-accuracy, high stability and high reliability of long time on-line monitoring outdoors, underground mine and indoors. ETCR2800C Multifunction Non-Contact Resistance Online Tester is equipped with LCD display and alarm light, which can observe grounding resistance value at any times and set the alarm critical val. Alarm light will flash when measured value is beyond pre-set critical value. Detector applies to electric transmission line pole ground connection, underground mine device ground connection, meteorological lightning protection grounding connection, petrochemical engineering ground connection, communication ground connection, rail facility ground connection, building the warehouse ground connection, electrical equipment ground connection etc.. Detector provides power supply and RS485 signal interface, and standard MODBUS-RTU communication protocol,which user can do secondary development to realize remote monitoring. ETCR2800C’s LCD shows measured value directly, also sets up Detector’s alarm critical value, and possess audible and visual alarming function, which is very suitable to Independent installation and use when it needn’t form a network.
