LB3980 Voltage Calibration

You Are Currently Here:Home > Training > LB3980 Voltage Calibration

All our product and control boards have been calibrate and QC serval times before delivery, customer no need to do the calibration at their end, but in case you need to do it somehow, the instruction bellow would be useful

1. Click”系统管理

2. Click”参数管理

3. Click”零点校正”

4. Click”Enter” to do an auto Zero Point Calibration

5. After auto Zero Point Calibration complete, it shows “校正完成!”, return to previous menu

6. Click”计量校正”

7. Click”电压校正”

8. Total 4 voltage “72V”, “162V”, “325V” and “760V” need to calibrate, we go with 72V first

9. In this step “实际电压:24:00V” means you need to get the unit an input voltage supply about 24V

10. Measure the exact voltage you supply to the unit, in this example the real input voltage i measured is 25.18V, so i set “实际电压:25.18V”, then Enter, you would see”1″ and “1”, same in the picture, it means the first point calibrate is complete

11. Use → and ← go to next page to set the second calibration point, in this step “实际电压:65:00V” means you need to get the unit an input voltage supply about 65V

12. Measure the exact voltage you supply to the unit, in this example the real input voltage i measured is 65.18V, so i set “实际电压:65.18V”, then Enter, you would see”2″ and “2”, same in the picture, it means the second point calibrate is complete

13. Click Enter, go to “参数保存” to save the calibration

14. Use password 9577 to save and update the calibration. After that, repeat steps 6-14 to calibrate the other 3 voltage 162V, 325V and 760V
