Product Introduction

AI-6301B Automatic Earth Test Set is designed to measure the resistance or impedance of ground devices and soil resistivity. It is equipped with frequency conversion and digital filter technique that enable high interference suppression performance. Readings are displayed on LCD and can be printed out with internal printer. The set is portable and works with internal battery.

Product Features

▪ Interference Suppression：
AI-6301B is based on frequency conversion and digital filter technique. It tests at 55Hz, which tracks the interference frequency 50Hz or 60Hz. The interference is suppressed to about -80db after digital filtering. AI-6301B is suitable to test ground resistance at heavy interference site such as power plant or switch yard.

▪ High Accuracy：
There are two isolated circuits to sample current and voltage signals 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 instead of hardware. The maximum output current is 0.2A which is helpful to get more accurate readings than some meter works at mA level.

▪ Easy to Operate：
After make selection on a very simple menu and start test, readings are dynamically displayed on LCD. After stop test, data can be printed out or stored.
The meter can stores 100 groups of data. All data can upload to PC by RS232 or Bluetooth communication interface.

▪ Safety：
The maximum output voltage is 36V. It is much safer than high voltage test set.
