The NT631/NT631C has the following initialization functions. Use them as necessary.

• Clearing screen data	page 135
• Initializing memory tables	page 141
• Initializing memory switches	page 143
• Initializing display history record data	page 137
• Initializing alarm history record data	page 138
• Initializing recipe tables	page 140

Reference: If writing to the screen data memory has been disabled by the System Setting setting in the System Installer mode, memory initialization is not possible.

6-4-1 Clearing Screen Data

Use this function if the screen data has been corrupted and the NT631/

NT631C cannot be started up correctly.

This operation clears (initializes) only the screen data and contents of the cal- culation tables. The memory switch settings and display history/alarm history record data are retained.
