1Parameter settings for displacement display instrument: When there is no password protection）Press the function key during normal operation（MO）More than seconds, the main display window showsPn-00

2To enter the parameter settings, you can use the ↑↓ keys to loop through the display until you want to modify the parameter Pn-XX）When the main window displays parameters“Pn-XXAfterwards, press the OK button（

3En ）Entering the parameter setting state, the last digit of the parameter displayed in the main window is flashing;）To modify the value, make sure the current modification bit is the flashing bit. If not, you can press the function key（MO）Cycle from right to left to change the position of the flashing bit, with different parameters displaying different numbers of bits. Use the ↑↓ keys to change the value, set the parameters, and then press the OK button（En）Jump out of parameters

4Pn0XX The setting,）Press（

5MO ）Return to work mode.）When entering any state in the settings, if you press the reset button（

2CL.

）The exit will not be saved, but the newly modified parameters will be temporarily valid until the power is turned off (except for the serial port baud rate), and will be restored to their previous settings when powered on again. This function can be used to view parameters.When there is password protectionWhen the function key is pressed and the above method is used to enter the corresponding settings, the main window will display“0000Pn-CO.”Enter password input mode. At this moment, the window displaysFlashing at the lowest position, follow the above steps and use the ↑↓ keys and function keys（MO）Enter the correct password and press the OK button（En）Confirm that the program has entered the parameter setting state. If the password is entered incorrectly or the reset button is pressed（

CL.）Then the program returns to its working state.III
