1. Supply a power to the indicator after distributing power lines.
2. Set up indicator as indicated in the instruction.
3. Test the calibration indicated as in the instruction of Digital indicator.
4. Press a quarter of maximum capacity on the upper parts of loadcells which is to be adhered.
5. There are unbalanced load points, which is happened by the load of system.
6. Turn the multi trun resistivity of a summing box to the right direction to go up the load,or left.
7. Coordinate repeatedly the multi trun resistivity like the case of No.5 above to even up the load of 4 points
8. Set on calibration as indicated in the digital indicator.
