For on line inspection devices such as Pilot Profiler and Pilot Vision, training is very critical for guarantee the success of project. However we sometimes see either those trainees did not grasp the training fully or those who learned well changed job. During Pilot Profiler installation at Coca Cola Guangxi Beverages, we encouraged the customer to use a digital camera to film or record the training especially those key steps for doing proper operation and setup so customer could do internal refresh-training at any time in order to make sure those operators could handle the operation/setup properly.
