1, making record data samples and testing. 2, the test instrument is placed at the edge of the experimental work station, convenient operation to make the adjustment handle. 3, according to the requirement of products and choose a suitable mandrel. The mandrel insert tester base and holes, and fixed. 4, turn the adjustinghandwheel lower plate, the model will be inserted into the film oriented between shaft and handle, and the carrier with the fastening screws and a sample pressing. 5, turn the adjustinghandwheel lift pallet of the model close to the mandrel. 6, lower the adjustment handle to the lowest position, adjust the knob on the handle pressing shaft, the pressing shaft tightly model. 7, up regulating handle, in 1-2S slowly lift 180 degrees, the axis of the sample plate is bent 180 degrees. 8, rotate the hand wheel adjustment, lower plate, the shaft rod bending model left out. 9, the model test results of judgment: After bending, immediately check the model, according to the requirements of product standards with normal vision or with 10 times the magnifying glass to check whether the coating crack or fall off.
