In order to ensure the correct weight of the weighing scale and the linearity of the
weight change, each weighing scale needs to carry out weight calibration and dynamic
calibration.For specific operation methods, please refer to "Operation Instructions on
Buttons and Operation Frames" in section 3.3.2.

3.6.1 The weight calibration scale
In the setting page, click "Static calibration" to enter the interface of weight
calibration, follow the steps on the touch screen to calibrate the scale, and click "Exit" to
return to the main interface after the calibration is completed.For specific operation
methods, please refer to "Operation Instructions on Buttons and Operation Frames" in
Section 3.3.2.
 During calibration, ensure that the weighing scale is in the stopped state; otherwise,
the interface of the weighing scale cannot be entered;Calibration should ensure that
there is no item on the weighing platform, no vibration on the weighing platform, and
no relatively strong air flow around the weighing scale.
 When the weighing platform is empty, ensure that the weighing platform is at zero
position and stable. Otherwise, please eliminate interference and click "Calibrate the
weighing platform". The second step can only be carried out when the touch screen
indicator is 0 and the stability sign is lit.
 When placing the weight, try to avoid the weight hitting the surface of the weighing
platform. Enter the correct weight into the weight box of the weighing platform,
otherwise it will lead to inaccurate calibration scale or calibration failure (the weight of
the weighing platform should be greater than the product weight and not exceed the
maximum range of the weighing scale).
 If the calibration fails, please check whether the scale is stable and whether the sensor
is interfered by the outside world or whether the scale is in contact with other
equipment, and re-calibrate after troubleshooting.
3.6.2 Dynamic calibration of scale
On the product page, click "Dynamic calibration" to enter the dynamic calibration
interface, and perform dynamic calibration according to the text prompts. When completed,
relevant parameters will be automatically calculated and generated and product parameters
will be written.Click "Exit" to return to the main interface after completion of calibration.For
details, please refer to Section 3.3.2 "Operation Instructions for Buttons and Operation
Frames".

 Calibration must ensure that the check scale in the stopped state, otherwise can not
enter the dynamic calibration interface;When calibrating, ensure that there is no item
on the scale, no vibration on the scale, and no relatively strong air flow around the
scale.
 When the weighing platform is empty, it should be ensured that the weighing platform
is at zero position and stable, otherwise, please eliminate external interference and
carry out "zero clearing" operation.
 When placing the product, the product should avoid hitting the surface of the weighing
platform. Only after the weight is stable can you click "Obtain static weight";If the
product has a gross weight value, please set the gross weight value first before
dynamic calibration.
 The default value of learning times is 10. If the learning result is not accurate, you can
increase the learning times appropriately.If the production requirement is not high, the
learning times can be appropriately reduced to improve the learning speed;External
interference should be avoided in the learning process, and the system will
automatically save the learning results and display them after the completion of
learning.
 The change of product detection speed requires dynamic calibration again.
 The principle of dynamic calibration, attention to implementation and alternative
methods are introduced in detail in the interface of dynamic calibration parameter help.
If necessary, you can click Help to view.
Correction factor The standard value is 1000. After the number of dynamic
calibration is completed, the controller will automatically
calculate this value according to the dynamic result and static
weight.
If it is not convenient for dynamic calibration, you need to
enter this value manually, which can be set in the product
parameter interface, and fill in the size of the value refer to the
method in the dynamic calibration parameter help interface
