DigitalFlow™ XGF868i Service Manual 1
Chapter 1. Calibration
Chapter 1. Calibration
1.1 Introduction
Calibrating the XGF868i 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 frequency outputs - page 6.
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 XGF868i, 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 9 as a guide in following the calibration instructions.
1. Power up the XGF868i 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
XGF868i to restart.

Chapter 1. Calibration
2 DigitalFlow™ XGF868i Service Manual
1.3 Calibrating and Testing the Analog Outputs
Every XGF868i flowmeter includes two built-in analog outputs (A and B) at terminal block J1, which is designated as
Slot 0. Additional analog outputs may be added to the Model XGF868i by installing an appropriate option card in
Slot 1. This option card contains two analog outputs, which are also designated as A and B.
Before beginning calibration, an ammeter must be connected to the desired analog output. Both the zero-point and
full-scale values for all of these outputs must be calibrated. After calibrating the outputs, which have a resolution of
5.0 A (0.03% full scale), their linearity should be tested.
Note: The zero point of the analog output may be set at either 0 mA or 4 mA. However, the calibration always uses
the 4 mA point, as the meter extrapolates this value to obtain the 0 mA point.
1.3.1 Preparing for Calibration
Prepare for calibration by inserting an ammeter in series with the load on the desired output. Refer to Figure 1 below
and Figure 4 on page 10 to identify the OUT(+) and RTN(-) pins for the desired output.

Chapter 1. Calibration
1.3.2 Calibrating the Low End of the Output Range
1. From the Keypad Program, press the right arrow key to scroll to the CALIB menu. Press [Enter].
2. In the Cal menu, scroll to the Slot 0 or Slot 1 option, and press [Enter].
Note: The Slot 1 option only appears in the menu if an option card has been installed in this slot.
3. Scroll to either Output A or Output B to open the Analog Output menu. (Output A will be used as an example in
this manual.) Press [Enter].
IMPORTANT: The procedure for calibrating Output B is identical to that for calibrating Output A. However, when
calibrating Output B, be sure to reconnect the ammeter on terminal block J1. See Figure 1 on page 2 for
the correct pin numbers.
4. Scroll to 4 mA to calibrate the low end of the output range. Press [Enter].
5. Scroll to UP or DOWN to adjust the ammeter reading UP or DOWN, until a 4 mA reading is achieved,
or
Scroll to Numer, and directly enter the mA reading. In either case, press [Enter] to confirm the entry.
6. Once you have achieved a 4 mA reading, scroll to either STORE to store the calibration, or to ABORT to exit the
menu without storing the calibration. In either case, press [Enter].
Note: If the ammeter reading cannot be adjusted within 5.0 A of the 4 or 20 mA setting, contact the factory for
assistance.
1.3.3 Calibrating the High End of the Output Range
7. The XGF868i returns to the Analog Output window. Scroll to 20 mA, and repeat steps 4 and 5 to calibrate the high
end of the output range.
Note: Skip the following prompt, if linearity testing of the output will not be performed at this time.
1.3.4 Testing Output Linearity
8. Scroll to TEST to test the linearity of the currently selected analog output. Press [Enter].
9. Check the ammeter reading at 50% Full Scale. Then, use the arrow keys to enter a different % Full Scale (0-100%).
Press [Enter] when done.

Chapter 1. Calibration
4 DigitalFlow™ XGF868i Service Manual
Table 1 below lists the expected ammeter readings at various % Full Scale settings, for both 4-20 mA and 0-20 mA
scales. Refer to this table to verify the accuracy of the ammeter readings taken above.
If the linearity test readings are not within 5 A of the values listed in Table 1, check the accuracy and wiring of the
ammeter. Then, repeat the low and high end calibrations. If the analog output still does not pass the linearity test,
contact the factory for assistance.
10. Scroll to EXIT and press [Enter] to return to the Cal menu. Then choose another output to calibrate or press [Escape]
to leave the CALIB menu.
This completes calibration of the Slot 0 analog outputs. Proceed to the appropriate section to calibrate additional
inputs/outputs.
1.4 Calibrating the Analog Inputs
Analog inputs may be added to the XGF868i by installing an appropriate option card in Slot 1. This option card
contains two or four analog inputs, which are designated as A, B, C and D. Both the zero-point and full-scale values
for each input must be calibrated.
Calibration of the analog inputs requires the use of a calibrated current source. If an independent calibrated current
source is not available, one of the Slot 0 analog outputs may be used for the calibration. During the analog input
calibration, the Slot 0 analog output will supply the low reference, high reference, 4 mA and 20 mA signals at the
appropriate times.
IMPORTANT: If a Slot 0 analog output will be used to calibrate the analog inputs, the Slot 0 analog output calibration
procedure must be completed first.

Chapter 1. Calibration
1.4.1 Preparing for Calibration
Prepare for the calibration procedure by connecting a Slot 0 analog output (or an independent calibrated current
source) to the desired input on the option card. See Figure 4 on page 10 to identify the IN(+) and RTN(-) pins for the
desired input on terminal block J2.
Note: The zero point of the analog input may be set for either 0 mA or 4 mA. However, the calibration always uses
the 4 mA point, as the meter extrapolates this value to obtain the 0 mA point.
1.4.2 Accessing the Calibration/Test Menu
1. From the Keypad Program, press the right arrow key to scroll to the CALIB menu. Press [Enter].
2. In the Cal window, scroll to Slot 1. Press [Enter].
3. Scroll to the desired Input to open the ANALOG INPUT menu. (Input A will be used as an example in this manual.)
Press [Enter].
IMPORTANT: Calibrating Input B, C or D is identical to calibrating Input A. However, be sure to reconnect the current
source on terminal block J2. Refer to Figure 4 on page 10 for the correct pin numbers.
4. Scroll to the appropriate option to select the reference point to be calibrated. Press [Enter].
IMPORTANT: The procedure for calibrating all the inputs is the same. However, when calibrating a different input, be
sure to reconnect the current source at terminal block J2. See Figure 4 on page 10 for the correct pin
numbers.
5. Do one of the following:
•Proceed to the “4 mA Option” on page 5.
•Proceed to the “20 mA Option” on page 5.
1.4.2.1 4 mA Option
Set the calibrated current source to 4 mA.
• If you selected the 4 mA option in the ANALOG INPUT menu, scroll to STORE to accept the current 4 mA value or on
ABORT to cancel the entry. Press [Enter]. In either case, the XGF868i returns to the Analog Input window.
1.4.2.2 20 mA Option

Chapter 2. Error Codes
Chapter 2. Error Codes
2.1 Introduction
The XGF868i ultrasonic flow transmitter is a reliable, easy to maintain instrument. When properly installed and
operated, as described in the Startup Guide, the meter provides accurate flow rate measurements with minimal user
intervention. However, if a problem should arise with the electronics enclosure, the transducers or the flowcell, a
built-in error code message system greatly simplifies the troubleshooting process.
All of the possible XGF868i error code messages are discussed in this chapter, along with the possible causes and the
recommended actions. When an error code is generated, it will appear on the LCD as shown in Figure 5 below.
Figure 5: Error Message Location
If an error message appears during normal operation of the Model XGF868i, refer to the appropriate section of this
chapter for instructions on how to proceed.

Chapter 2. Error Codes
12 DigitalFlow™ XGF868i Service Manual
E0: No Error
Problem: No error condition currently exists.
Cause: This message appears briefly to confirm that the response to another error message has corrected the
problem.
Action: No action is required.
E1: Low Signal
Problem: Poor ultrasonic signal strength or the signal exceeds the limits entered via the Keypad Program.
Cause: Poor signal strength may be caused by a defective cable, a flowcell problem, a defective transducer or a
problem in the electronics console. A signal that exceeds the programmed limits is probably caused by
the entry of an improper value in the Channelx-Set up-Signal submenu of the Keypad Program.
Action: Using the procedures in Chapter 3, Diagnostics, check the components listed above. Also, check the limit
values entered into the Channelx-Set up-Signal submenu, as described in Chapter 1, Programming Site
Data, of the Programming Manual.
E2: Sound Speed Error
Problem: The sound speed exceeds the limits programmed in the Channelx-Set up-Signal submenu of the
Keypad Program.
Cause: The error may be caused by incorrect programming, poor flow conditions or poor transducer orientation.
Action: Compare the measured sound speed to tabulated nominal values for the gas being used and correct
any programming errors. Refer to Chapter 3, Diagnostics, to correct any flowcell and/or transducer
problems.
E3: Velocity Range
Problem: The velocity exceeds the limits programmed in the Channelx-Set up-Signal submenu of the Keypad
Program.
Cause: This error may be caused by the entry of improper programming data or by poor flow conditions and/or
excessive turbulence.
Action: Make sure the actual flow rate is within ±75 ft/sec (±23 m/sec). See Chapter 1, Programming Site Data, in
the Programming Manual for details. Refer to Chapter 3, Diagnostics, to correct any flowcell and/or
transducer problems.
