3.4 Initial power on screens
When you power On the PanaFlow Z1G/Z2G Process Gas
Flowmeter , the display first shows the model name and
software version:
The meter then starts to display measured parameters.
To enter the Keypad Program, press the [

] key, followed by
the [

] key, and the [

] key again. Each successive key must
be entered within 10 seconds of the prior key.
As a guide in following the programming instructions in
this chapter, the relevant portions of the PanaFlow Z1G/Z2G
Process Gas Flowmeter menu map can be found in Figure 16
on page 21 . Proceed to the following sections to enter data in
the Channel or GLOBL menus.
IMPORTANT:
If the keypad has not been pressed for 10 minutes, the
PanaFlow Z1G/Z2G Process Gas Flowmeter exits the Keypad
Program and returns to displaying measurements.
The meter retains any configuration changes that
were confirmed with the [

] key, and restarts as if the
programming had been completed.
3.5 Entering data in the GLOBL
menu
To begin programming your meter, you must select the
system units from the GLOBL menu as discussed below.
Refer to Figure 16 on page 21 and remember to record all
programming data in Appendix B, “Gas Process Flowmeter
Service Record”.
3.5.1 Entering global system data
The GLOBL-SYSTM submenu is used to enter several general
system parameters (e.g., English or metric units). For
meters 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. Complete the following steps:
1. In the Keypad Program, scroll to PROG and press [

].
2. In the PROG menu, scroll to GLOBL and press [

].
3. In the Global PROGRAM menu, scroll to SYSTM and press
[

].
4. Scroll to the desired System Units selection (either
metric or English) and press [

] to display all
parameters and measurements in the designated units.
5. Scroll to the desired Pressure Units selection (absolute or
gauge) and press [

].
6. Do one of the following:
• If PSIa (absolute) was selected, skip this step.
• If PSIg (gauge) was selected, enter the desired
atmospheric pressure and press [

].
7. The program automatically returns to the Global
PROGRAM menu.
3.5.2 Selecting volumetric units
1. Scroll to the desired Volumetric Units for the flow rate
display and press [

]. Table 4 below lists the available
volumetric units.
Table 4: 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
2. Scroll to the desired unit of Volumetric Time (from
seconds to days ) and press [

].
3. Scroll to the desired number of Vol Decimal Digits ( digits
to the right of the decimal point) in the volumetric flow
display and press [

].
3.5.3 Selecting totalizer units
4. Scroll to the desired Totalizer Units for the flow rate
display and press [

]. Available units are listed in Table
4 above.
5. Scroll to the desired number of Tot Decimal Digits (digits
to the right of the decimal point in the totalized flow rate
display) and press [

].
6. Do one of the following:
• If
MASS FLOW is ON , proceed to “Selecting Mass Flow
Units” on page 26 .
• If MASS FLOW is OFF , the meter returns to the Global
PROGRAM window. Press [

] twice and proceed to
Chapter 4, “Operation”.
Note: The following prompts appear only if Mass Flow is
activated for both channels.
