If the result is the same as default parameters or previously programmed ones, then communication has
been done correctly.
If the result is as shown in the following three images, then communication has not been done correctly.
Note: Place the target with proper air gap distance if it won't read EEPROM correctly. Then, try to read
again. Adjust the target until it reads correctly.

3.2 How to Capture Data Using IPCE Manually
If data cannot be captured by a motorized automatic system, then it can be done manually using IPCE.A
position measurement tool is required to get an accurate position value (linear or rotary/angular).After
locating the target at a given position, then record this value.Then, collect data using the customer’s
bench test system.Replace the position/measured data into template file.
