ES3022 Multifunction Clamp Earth Tester having a 2.4" color screen provides the following measurement functions: earth resistance measurement by clamp method, three or four wire resistance measurement, AC voltage and current measurement.
Other functions are storage of measurement values, data recall to the screen, settable limit values and alarming by the set limit as well as automatic power off
The microprocessor controlled ES3022 Multifunction Clamp Tester accurately measures the earth resistance. The fast filtering technology minimizes the interference effect so insuring stable and accurate measurement
The maximum 500 measured value groups stored in the instrument memory can be downloaded to a memory stick by means of the USB interface.
The shock-, dust-, and moisture-proof design insures good protection against mechanical effects.
