1.4 Activating a channel
The channelx-ACTIV submenu permits selection of the
desired measurement method. In addition, it is used
to activate/deactivate one or both of the channels in a
2-channel XGF868i.
While following the programming instructions, refer
to Figure 28 on page 40 . To access the channelx-ACTIV
submenu:
1. In the
keypad program , scroll to prog and
press [enter].
2. In the prog menu, scroll to CH1 or CH2 and
press [enter].
3. In the channel program menu, scroll to ACTIV and
press [enter].
4. Scroll to burst to activate the channel/path, and
press [enter].
5. Scroll to one of the measurement methods described
below and press [enter].
• Skan only is the preferred technique for locating the
acoustic signal and for high velocity measurements.
It is more robust in a noisy environment than the
measure technique.
• Skan/measure is the preferred technique to use for
low velocity measurements.
If skan only is selected at the above prompt, the meter
uses this technique exclusively. However, if skan/measure
is selected, the meter uses skan only to find the acoustic
signal and then tries to use the skan/measure technique
for the actual measurement.
NOTE: To change the skan only and skan/measure
parameters, see the signal submenu section of
this chapter.
Procedure options
After completing the above step, the XGF868i returns to the
channel program window. Do one of the following:
• To continue entering “quick startup” data, proceed
to step 3 in the following section.
• To continue regular programming, refer to
Appendix A. Menu Maps on page 39 , to navigate
to the desired menu.
• To leave the keypad program , press [escape] twice.
1.5 Entering system data for
the channel
The channelx-system submenu is used to enter
system parameters for the channel. While following the
programming instructions, refer to Figure 28 on page 40 .
1.5.1 Accessing the channelx-system submenu
1. In the keypad program , scroll to prog and
press [enter].
2. In the prog menu, scroll to CH1 or CH2 and
press [enter].
3. In the channel program menu, scroll to systm
and press [enter].
4. Use the arrow keys to enter the desired channel label
(up to 5 characters) and press [enter].
5. Use the arrow keys to enter the desired site/channel
message (up to 21 characters) and press [enter].
1.5.2 Selecting volumetric units
1. Scroll to the desired volumetric units for the flow rate
display and press [enter]. Table 1 lists available units.
2. Scroll to the desired volumetric time units for the
flow rate display and press [enter].
3. Scroll to the desired number of vol. decimal digits
(digits to the right of the decimal point in the
volumetric flow rate display) and press [enter].
Table 1: Available volumetric/totalizer units
English Metric
ACF = Actual cubic feet ACM = Actual cubic meters
KACF = Thousands of ACF KACM = Thousands of ACM
MMACF = Millions of ACF MMACM = Millions of ACM
SCF = Standard cubic feet SCM = Standard cubic meters
KSCF = Thousands of SCF KSCM = Thousands of SCM
MMSCF = Millions of SCF MMSCM = Millions of SCM
