Digital Earth Resistance Soil Resistivity Tester

Kusam Electrical Industries Ltd has introduced a new “Kusam-Meco” Digital Earth Resistance Soil Resistivity Tester with 2/3/4 wire measurement, Model KM 1320. It can be used specially for measuring earth resistance, soil resistivity, earth voltage, AC voltage, adopting the latest digital and micro-processer technology for precise 4-pole, 3-pole and simple 2-pole method for earth resistance measurement. This meter has 4-digit super large LCD display of host machine with blue backlight and bar graph indication that can be seen clearly in dim places. At the same time it can store 300 sets of data, fulfilling historical inquiry and online real time monitoring through monitoring software, dynamic display, alarm indicator, and with the functions like historical data access, reading, preservation, report forms, printing and so on. It measures earth resistance from 0.00 ~ 30.00 Ohms with 5 times/sec measuring rate; soil resistivity from 0.00 Ohms ~ 9000 kilo Ohms with measuring rate 5 times/sec; and earth voltage AC 0.0~600 V with 3 times/sec measuring rate. Measuring method of earth resistance is by rated current change-pole method, soil resistivity by 4-pole measurement and earth voltage by average rectification (between P(S)-ES). Frequency measurement ranges are 28 Hz/111 Hz/105 Hz/94 Hz (AFC). The short circuit test current is AC 20 mA max and open circuit test voltage is AC 40 V max. It has Data Storage, Data Hold, Data Access (Read) and Alarm functions, and also electromagnetic feature. It display “OL” icon on display when exceeding measuring range is over range and also displays “Noise” icon when interference voltage exceed 5 V. It can measure auxiliary earth resistance 0.00 kilo Ohms. The insulation resistance is over 20 Mega Ohms (between circuit and enclosure @ 500 V DC) and withstanding voltage AC 3700V/rms (between circuit and enclosure).
