  1. CustomMenu instructions apply to the CR1000KD, CR850, and CR3000 display. Custom menus are not displayed or passed through to the terminal interface. 

  2. In OS 24 (CR6 OS 01) and later, a user can change constants from the CR1000KD or a terminal emulator without touching the program. The program must contain a ConstTable/EndConstTable construction for this to occur. Because the program does recompile, collect the data first.

  3. Yes. The CD100 mounts in an enclosure door and supports all of the CR1000KD capabilities. With the CD100, historic and real-time data can be read, and instructions can be entered without opening the enclosure door.

    Other available options that display real-time data only are the CD295 and CD294.

  4. Although it is recommended to use software such as Short Cut for programming, the CR800-series, CR1000, and CR3000 dataloggers can be programmed with the CD100, CR1000KD, or integrated keypads. The keypad can be used to create new programs or edit programs that already exist in the data logger memory.

    From the CD100 or CR1000KD home screen, follow these steps to get started:

    1. Press Enter
    2. Select File and press Enter
    3. Select either New or Edit
      • To modify an existing instruction, select the instruction, and press Enter
      • To add a new instruction, press Ins, and select Instruction.
