2.4 Entering Data in the Global Menu
To begin programming your meter, you must select the system units from the GLOBL menu as discussed below. Refer to
Figure 15 on page 41 and remember to record all programming data in Appendix B, Data Records.
Note: Refer to the Programming Manual for information on the other submenus in the GLOBL menu.
2.4.1 Entering Global System Data
The GLOBL-SYSTM submenu is used to enter several general system parameters (e.g., English or metric units). For units
with 2 channels, this menu is also used to compute parameters such as the sum, difference or average of the channel 1
and channel 2 signals. When calculating the SUM, DIF or AVE readouts, data from the GLOBL-SYSTM submenu is used.
Any conflicting data entered in the CHANNEL-SYSTM submenu is overridden.
1. In the Keypad Program, scroll to PROG and press [Enter].
2. In the PROG menu, scroll to GLOBL and press [Enter].
3. In the Global PROGRAM menu, scroll to SYSTM and press [Enter].
4. Scroll to the desired System Units selection (either metric or English) and press [Enter]. The XGM868i will display
all parameters and measurements in the designated units.
5. Scroll to the desired Pressure Units selection (absolute or gauge) and press [Enter].
6. Do one of the following:
• If PSIa (absolute) was selected, proceed to Step 7.
• If PSIg (gauge) was selected, enter the desired atmospheric pressure, press [Enter] and proceed to Step 7.
7. Do one of the following:
• For a single-channel XGM868i, the program returns to the Global PROGRAM menu.
