Product Introduction

AI-6301 Automatic Earth Test Set is designed to measure the resistance of ground devices and connection resistance between ground devices. AI-6301 is equipped with frequency conversion power supply that enables high interference suppression performance. The set can get both impedance and resistance results. Readings can be displayed on LCD and can be printed out with internal printer.

Product Features

▪ Interference Suppression：
AI-6301 adopts frequency converter and digital filter technique. For example, when use 45Hz / 55Hz dual frequency mode, it tests with 45Hz and 55Hz then calculates the results to 50Hz. 50Hz interference is eliminated during the test.

▪ High Accuracy：
There are two isolated circuit to sample current and voltage signals separately which consists a true four terminal circuit for low impedance test. All Input signals are converted to digital signal by high accurate A/D converters, and then processed by a DSP. Most of the tasks are done by software.

▪ Easy to Operate：
All test work will be done automatically after start the set: raise up the voltage, testing, ramps down voltage to zero, displays the results and print them out.
The test set can save 100 groups of data. Through the serial port, a computer can remote the set, get results, or update the software of the set.

▪ Safe Protection：
There are multiple protections for safe operation. An alarm beeps while testing.
