MS2308 is an advanced earthing-resistance testers integrated with multiple measuring methods, can be used for checking earthing-resistance of transformer, anti-lightning system, high-voltage power tower, and communication equipment, and its automatic frequency control (AFC) function can bring interference to an absolute minimum.With 3-pole/4-pole earthing-resistance testing function, the earthing resistance of single-point earthing system and soil resistivity can be measured. With 3 pole/4 pole method and current clamp, resistance of a single branch circuit in an inter-connecting network can be tested without disconnecting the earthing system; With current clamp and voltage clamp and voltage clamp, resistance in an inter- connecting network can be tested without disconnecting the earthing system.
For Testing the Earthing-Resistance of Electrical Equipment
For Testing the Interference Voltage of External Circuits
For Testing the Interference-Current of External Circuits
For Testing the Average Soil Resistivity
For Testing Resistance with 2-pole AC Voltage
