4.2 Programming tips 
• 
See Section 3 for general programming procedures. 
• 
Before programming a function block’s input parameter with a CV’s (Calculated Value) output 
parameter, you must program the CV first; otherwise, the CV’s output parameter will not be 
available for programming. 
• 
The function block SY (System Parameter) operates internally and has no menu.  It automatically 
produces outputs which reflect the status of alarms, data storage, diagnostics, and reference 
junction temperature.  These outputs can be programmed as inputs to function blocks.  See Table 
3-5 in Section 3. 
• 
Each function block can be labeled with custom descriptors and tags to identify the function on 
displays.  You can enter these labels under the menu item ENTER LABELS or within each function 
block’s menu item.  See Section 4.4 Frequently used programming prompts. 
• 
All Program mode menu items and settings can be reviewed but not changed in the Online mode 
by selecting “REVIEW PROGRAMMING” on the main Online menu.  See Enable Features, Section 
4.19. 
• 
We recommend you save the instrument configuration to a floppy disk after you have completed 
programming the instrument.  See 4.23 Access LOAD/STORE CONFIG.
