Flow IiValue is in " source strength zero " U0iValue, I0iIn the preset range of value, then the zero of X-ray uclear scale is influenced by the operating mode of conveyer
There is deviation, needs to remeasure " gage zero ", and " gage zero " that newly measures is saved in " gage zero-source strength zero
In point " array；If the tube voltage U of x-ray sourceiValue, tube current IiValue and " source strength zero " U0iValue, I0iThe error of value is more than pre-
If range, then illustrate that the tube voltage of X-ray and tube current parameter shift, then weighing instrument determines the variable quantity feedback of source strength
High voltage power supply control module is given, tube voltage, the tube current parameter of x-ray source are adjusted, X-ray is kept to stablize, ensures " metering zero
