DigitalFlow™ XGM868i Service Manual 1
Chapter 1. Calibration
Chapter 1. Calibration
1.1 Introduction
Calibrating the Model XGM868i’s analog outputs and inputs is explained in this chapter. In addition, testing the
optional totalizer, frequency and alarm relay outputs is discussed. The chapter includes the following specific topics:
• calibrating the Slot 0 and Slot 1 analog outputs - page 2.
• calibrating option card analog inputs - page 4.
• calibrating option card RTD inputs - page 6.
• testing option card alarm relays - page 7.
• testing option card totalizer outputs - page 8.
• testing option card frequency outputs - page 10.
Note: Convention in this manual identifies any expansion slot as Slot x, where x is a number from 0-2. Slot 2 is used
only for data logging, MODBUS or HART option cards.
See Chapter 1, Installation, and Appendix B, Data Records, in the Startup Guide for a complete description of the
available option cards and the procedures for wiring them.
1.2 Accessing the Calibration Menu
The Calibration menu is accessible through the Keypad Program, as well as through PanaView™ software. (If you are
using PanaView to calibrate the XGM868i, refer to Appendix B.) Use this menu to calibrate and test the Slot 0 analog
outputs, as well as to calibrate and/or test any option cards that are installed in expansion Slot 1. Refer to the menu maps
in Figure 3 on page 11 as a guide in following the calibration instructions.
1. Power up the XGM868i and wait until it has initialized.
2. Press the [Escape], [Enter], [Escape] keys. The Keypad Program appears on the screen.
3. Press the right arrow key to scroll to the CALIB menu. Press [Enter]. The Cal window opens.
Proceed to the appropriate sections of this chapter to calibrate and/or test any of the installed inputs and/or outputs.
Note: The Calibration menu never returns to the Keypad Program. Pressing [Escape] to exit the menu causes the
XGM868i to restart.
