12 Adjustment of zero count and full capability count value

12.1 Adjustment of zero count value：
 Remove 2*M4 inner Hexagon Sockets at the back of the balance with an
Allen wrench, and open the top cover of the balance.
 Open the inner cover of the balance core（4*M3inner Hexagon Sockets).
 Increase or decrease the additional weight at the front end of the balance
core, zero count value is as close as possible to 450.
 Reinstall the inner cover of the adjusted balance.
12.2 Adjustment of Full capability count value：
 Put 100g standard weight on the weighing pan to view Full capability
count value. The value should be 7800 to 8000.
 If Full capability count value is not in this range, an external resistor box
must be connected at R25. Full capability count value will be within this
range by the corresponding resistors in parallel.

13 Adjust Internal calibration weight value

Reference：For internal calibration balances, the internal weights class should be more
accurate than E2or F1，the error should be greater than the tolerance of the balance.
In order to eliminate the difference between internal weight and external weight, set to
calibrate the data.
Note：The setting is only for internal calibration balances. If the weighing
indications difference between internal weight calibration and external weight
calibration exceeds 3d, it needs to adjust internal weight value.
