Page 6: Chapter 3 Calibration & Adjustment
Chapter 3 Calibration and Adjustment 3.1 Turning on the power, and connecting the loadcell correctly, the indicator will perform self-checking, then turns into working mode (After turning on the indicator for more than 10 minutes, you can make the calibration). 3.2 Turning on the calibration switch on the back of the indicator, the indicator will go into the calibration mode, and display [n,****](**** is the previously set number), then you can set the calibration coefficients. - Page 7 will go to the next step. If you need not to change it, you can push [ C ] key to go to the next step. Step 9: Selecting manual zero-setting range: displaying [05 .**] Push [CH] key, .** will be 0.02, 0.04, 0.08, 1.00: representing respectively 2%, 4%, 8%, 100% F.S.
- Page 8 1, 2, 5, 10, 20, 50 optional by pushing [CH]. For example: 5 Pushing[Tare] [E 5] pushing [Tare] to confirm, then it will return to next step. If this number needs not to be changed, pushing [C ] Will get into next step. Pushing [CH] [d 0.0] Selecting the decimal position:...
- Page 9 pushing [C ] Will get into next step. Pushing [CH] [03 *.*] Choosing zero setting rate: 0.1, 0.2, 0.3 optional by pushing [CH]: meaning respectively the zero setting rate is 0.1e, 0.2e, Pushing[Tare] [03 0.3] 0.3e. Choosing one of them, pushing [Tare] to confirm, then it will return to next step.
- Page 10 pushing [C ] Will get into next step. Pushing[Tare] [CAL ] Deciding the zero position: Displaying [CAL] for 2 seconds, then it will [no Load] display [no load] automatically, checking if the scale is empty,waiting for about 10 seconds till the scale returning to zero stably, pushing [Tare] to confirm, then you can go to the next step.
