Grounding resistance tester VC4106 digital instrument ground shaking table Lightning detector
Basic measurement functions: 1.
2/3/4 pole method of grounding resistance measurement
Soil resistivity (rho) measurement.
Automatic interference voltage measurement.
2. Grounding resistance measurement using square wave excitation test, four test frequency (94 hz and 105 hz, 111 hz and 128 hz), can be manually choose, so as to avoid the interference sources, the measurement of grounding. Test of open circuit voltage, maximum 50 v; Short circuit current < 20 ma.
3. Can remove the residual resistance of test line
4. The overrun or incorrect warning function test conditions.
5. Panel calibration technology, to ensure that its should be the precision and performance.
