Product description

Earth ground resistance tester is a high-precision testing instrument used in various fields such as substations to test grounding resistance and related parameters.The instrument is of an integrated structure, with a built-in frequency conversion power supply module, and the output power supply is continuously variable in frequency. The frequency can be changed to 45Hz or 55Hz, the high-speed processor core is built in, and the high-end digital filtering technology is adopted, thus effectively avoiding the interference of power frequency electric field to the test and fundamentally solving the difficult problem of accurate measurement under strong electric field interference.

1. Real-time detection of each cell.
2.Multiple conditions (capacity, time, open circuit voltage, discharge platform, etc.) for battery sorting.
3.Automatically calculate the constant current charge ratio, capacity loss, discharge efficiency, average voltage, median voltage and other data.
4.Each batter y fully has its own constant current and constant voltage source, and its own loop does not affect each other.
5.Curve analysis and processing: curve analysis function.
6.Data export EXCEL and TXT file.

Using the most advanced AC discharge test method, it can accurately test the voltage and internal resistance at both ends of the battery, and judge the battery capacity and technical status of the battery. Customers can choose according to their own situation according to the internal resistance test, voltage test, and capacity estimation of batteries used in the communication industry. As the basis for the matching of the internal resistance of the new battery; the internal resistance of the battery is tested before and after discharge to identify the real backward battery; the key operation and the liquid crystal touch are two operating modes; it can test the battery in Strings or single cell.

Function:
Nowadays, many shoddy batteries are so dazzling in the market that we waste the most of our money unknowingly; Some battery protection boards are original, but the cells are set up afterwards; Some protection boards and batteries both are set up afterwards, some are the original but have been cycled hundreds of times, and it is sold again after the parameters are cleared; In short, Every situation could appear; with the battery test box emergence, these problems would go away! Cleaing and identifing only need one second, let the sham battery, high imitation battery nowhere to hide.

Writing the cycle times at random:
Double-click the button on the right to write randomly the cycles times of battery (1-9).

The times of battery cycles is cleared:
Click the right button, then, the times of battery cycles is cleared.

Battery charging activation:
The box needs to be connected to the charger, plug in the battery, short press the left button, it will enter the charging state, at this time, the battery current will display the charging milliamps, the default is maximum 500ma;
This function is for batteries which can not charge and need to be charged.

Special Reminder:
Regarding the problems that occurred during the upgrade process, if upgrade is successful but the instrument does not restart automatically, you need manually turn the power off and turn it on again.
If upgrade is unexpectedly interrupted or failed, you can turn off the power, then press the right button on the instrument and turn on the instrument again. Computer will prompt the instrument has been connected, upgrade mode, and now, you can upgrade again.

Precautions:
The instrument itself needs to be fully charged and used so that get an accurate test result. If the power supply is insufficient, please charge it in time. The upper right corner on the screen is the battery power of the instrument. If the screen dim out or flickering during the test, it is considered as low power. Please charge and use it
