Disassembling the GF2018 Current Logger with Insulated Rod Connector

Disassembling the GF2018 Current Logger with Insulated Rod Connector

This demonstration illustrates the standard disassembly procedure for the GF2018 logger equipped with an insulated rod connector. First, slowly rotate the rod body clockwise to loosen the connector, then gently lift the sensor away from the power cable. During normal disassembly, the sensor's electronic seal remains intact. The device can be connected to a computer via a 433 MHz wireless signal to download and view historical load data, and export it to Excel or PDF files. This is an indispensable operational guide for electrical maintenance teams and anti-theft inspectors. https://www.gfuvegroup.com/ammeter-recorder/high-voltage-power-load-recorder-with-wireless-current-sensor.html
