  • Page 12: Test Weight Calibration Mode

    ■ (Calibration) Adjusting “ZERO” Balance Adjust weight balance between “Real weight” on the load cell(Weight Part) and “Displayed weight of Indicator”. When you replace LOAD CELL or Indicator, you have to Calibrate process once again. (When you start calibration mode, TARE, HOLD & PRINT will be reset.) Before processing calibration, please warm up the indicator during 15 min to guarantee more preciseness.
