Securing guaranteed detection sensitivity and accurate rejection!
Daily inspection is very important.
1. Checking sensitivitySensitivity varies with the product temperature 1 and materials, and the ambient temperature.
2. Checking rejector operationCheck that contaminated products are rejected correctly by the rejector.
2
Check the operation at the start of the work day, when changing
products and at regular periods.
