INTRODUCTION
| MEWOI-BST4915 is a new generation of battery tester with touch-screen. It is strictly designed to evaluate and maintain all stationary power systems including Uninterruptible Power System. Via accurate testing of resistance and voltage, it gives an indication of battery capacity and technical status. The measurement data can be read on the instrument display directly. And it can also be uploaded to PC simply by using the USB drive. With the analyzing software, you could not only keep a record of the testing result but also have detailed analyzing for the status of batteries in different testing conditions. |
You can use either Test Clip or Probe Pin to conduct your test, bellow image would show you the right way to use them:
MAIN FEATURES
| 1.Wide test range: 5~6000Ah, compatible for single cell of 2V, 6V and 12V |
| 2.Smart and portable hand-held device, rugged and easy-to-go |
| 3.Colorful touch screen with optional operations of keyboard |
| 4.Simultaneously test for voltage, resistance and estimated capacity of batteries |
| 5.Online measurement, no need to remove battery and string from its system for testing, safe and convenient |
| 6.Fast testing for battery and string in seconds with testing data auto saving |
| 7.Strong anti-interference in high current with stable and accurate performance |
| 8.Testing frequency lower than10 Hz, effectively avoid interference from capacitive resistance of battery itself |
