Turn on the test instruments,after preheating for 20 minutes,adjust the instrument to ensure instrument pointer refers to zero or display shows zero initially,check the test fixture in contact with the equipment are in good connection.According to the resistance and accuracy requirement of flow process check point,set the nominal resistance meter to the specified value.On quality test of the resistance,the precision of the resistance must be within the prescribed range of error.
Weighting personnel,according to the different requirements of different resistance,group 50,100,200,500,1000 standard number of resistors according to the equivalent amount of weight on weighting machine.Bagging personnel will put the grouped resistors into a plastic bag,tag on each bag a certificate of approval,use a stapler or encapsulation machine sealing,and put into a circulation box.Simultaneously,in the process of initial assembly,packaging process and final packaging,the bagging personnel should check the weighting amount,to ensure accurate packing quantity.
