NR2600 series ground down conductor continuity tester (abbreviated as ground network continuity tester) is a newly designed portable tester with full Chinese character display, suitable for all kinds of power equipment ground down conductor and ground network (or adjacent equipment) Measurement of on-resistance between. The instrument is powered by a DC constant current power supply, and the measurement principle of the four-wire method is used to effectively eliminate the influence of the resistance of the test line on the test results, and the milliohm resistance data of the measurement loop can be directly obtained. Strong interference ability, easy to operate, rapid measurement data, accurate and reliable.
