15. At the prompt PULS.oUt , press INCR to select oFF or on for the pulse output
feature. If oFF is selected, press ENTER . If on is selected, see the section
Configuring Pulse Output .
16. At the prompt 4-20.oUt , press INCR to select oFF or on for the 4-20 mA output
feature. If oFF is selected, press ENTER . If on is selected, see the section
Configuring the 4-20 mA Rate Output .
17. At the prompt CodE , press I NCR to select oFF or on for the security code
feature. If oFF is selected, press ENTER. If on is selected, see the section
Setting a Security Code .
A detailed example of this method, using actual meter factors and step-by-step data
entry is below.
Example: Gas Measurement Using Preprogrammed Units of Measure
The MC-II
Plus Flow Analyzer will be connected to a 2” NuFlo standard range gas
turbine meter. The meter factor is 129.42 pulses per actual cubic foot. The volume
units of measure will be in thousands of standard cubic feet (MCF) and the rate units
of measure will be in thousands of standard cubic feet per day (MCF/D). The
average flowing pressure is 120 PSIG. The average flowing temperature is 50
degrees Fahrenheit. The base pressure is 14.73 PSIG and the base temperature is
60 degrees Fahrenheit. The atmospheric pressure is not
known but the elevation of the installation is 1000 feet above sea level. The 4-20
mA output, pulse output and security code are to be disabled. The input sensitivity
is to be left at 20 mV and no preprogrammed volume is to be entered. The MC-II
Plus Flow Analyzer has not been calibrated and all data in the MC-II Plus Flow
Analyzer is set to factory default. The MC-II Plus Flow Analyzer is in the Run Mode.
1. Press the
ACCESS key to enter the Calibrate Mode. The MC-II Plus Flow
Analyzer enters a self-diagnostics routine by performing a segment test that
momentarily displays all segments of the LCD. The firmware version is then
displayed by showing
Prog no on the upper line of the display and the firmware
version on the lower line of the display.
2. After the diagnostics routine is complete, the upper line of the display will show
the prompt tot Eng . Pressing INCR will select the engineering units of
measurement from BBL, GAL, M³, MCF, which are displayed on the right side of
the display or
USEr on the lower line of the display (factory default is BBL).
Press INCR until MCF is selected. Press the ENTER key to confirm the
selection.
3. The MC-II Plus Flow Analyzer will show the prompt tot d.P on the upper line of
the display and zeros with a decimal point on the lower line of the display. The
currently selected engineering units of measurement are also displayed (MCF in
this example). This prompt is requesting the decimal point position for the
