VI. Weighing and calibration of instruments
When the instrument is used for the first time or after using for a period
of time, the weighing error is large, so it is necessary to carry out weighing
calibration.The instrument can be calibrated in kind, and the calculation method
can be used in some cases where the physical calibration cannot be carried out.If
it is the initial calibration, the user needs to set the f parameters related to
weighing before entering the formal calibration step,The parameters involved are:

6.1 Physical calibration
The physical calibration is divided into two steps. The first step is zero
point calibration, and the second step is loading point calibration.Weighing
calibration operation is a user-1 level or above project, you must use the
corresponding password to log in.
The operation of zero point calibration is completed directly through the panel
buttons [reset 1] [set to zero 2]. If you do not log in with a password, the following
operations are performed manually.The specific steps are as follows:
