1.RS-232 serial interface enables the instrument to communicate with other computers.
2.Monitoring the dynamic variation of MN electrode potential through inspecting its ground resistance.
3.Receiver supports transient over-voltage protection for input voltage; transmitter supports over-voltage protection, over-current protection and AB open-circuit protection.
4.Automatically displaying the resistivity relative error between the current measuring result and the last measuring result.
5.Able to store measuring data for more than 150,000 times, including voltage, current, resistivity, relative error, SP, array constant, measuring point and so on.
