2) defective products that unusual because the production and testing process, and also have the opportunity to test grounding resistance instrument is damaged (repaired four times); prevent short circuit test hardware update for this;

2) because of production test in the process of bad quality, and at the same time they also have the opportunity test ground damage resistance of the instruments (has been repairing the 4); for this in order to prevent short circuit testing project hardware update;

2) because the production testing in the alpha process unusual bad product, but at the same time also have the opportunity to damage the testing grounding resistance equipment (Virginie repaired 4 times); to prevent short circuit test for this hardware update for the project;
