Pressing the DATA PAGE key again after the Fault Data title has been displayed will result in the display returning
to the Measured Data title and so on.
Line Down Key

move down one item at a time unless the button is held for over half a second in which case the scroll speed will
increase.

This key is used to store a setting parameter to the non-volatile EEPROM memory after a change has been made
using the above mentioned keys. After the key has been pressed the flash message ' DATA SAVED OK' will be
displayed. If for any reason the change has not been correctly stored the message ' WRONG PARAMETER SAVED'
will be displayed
If the STORE key is pressed whilst the display shows a Data parameter then the parameter currently being displayed
will be set as the default display which the MPC2000D will always revert to if no key is pressed for 5 minutes and
