Press STEP to proceed to the next digit (thousands position). Press INCR until 6
is displayed.
Press
STEP to proceed to the next digit (ten thousands position). Press INCR
until 8 is displayed.
Press
STEP to proceed to the next digit (one hundred thousands position).
Press INCR until 7 is displayed.
Press
ENTER to confirm the entry of the divisor.
7. The upper line of the display will show rAtE d.P prompting for entry of the rate
multiplier decimal point. The selections for the rate multiplier decimal point are
0.0, 0.00, 0.000, 0.0000 and 0.00000 (factory default is 0.0). Press
INCR until
0.00000 is displayed. Press ENTER .
8. The upper line of the display will show rAtE.FAC prompting for entry of the rate
multiplier (factory default is 1.00000). Enter the rate multiplier (.10986) in the
same manner as the divisor was entered in Step 6 and press
ENTER .
9. The upper line of the display will show the prompt
rAtE.dLY . The lower line of
the display will show the flow rate filter value in terms of the number of samples
required to reach 90% of the final value. The factory default setting is “nonE.”
The available settings are nonE, 5, 10, and 20. Press
INCR until 10 is displayed.
Then, press ENTER . (See the section Setting Flow Rate Filter to change the flow
rate filter.)
10. The upper line of the display will show inP.SEnS prompting for entry of the input
sensitivity in millivolts. Since the input sensitivity (factory default of 20 mV), pulse
output (factory default is off), 4-20 mA output (factory default is off) and security
code (factory default is off) are to be left at factory default settings, press
ACCESS to return to Run Mode. (Keep in mind that the unit for this example
was at factory default. Bypassing these steps in this case is acceptable. If the
MC-II
Plus Flow Analyzer had been previously calibrated and the settings of
these functions unknown, they must be stepped through to ensure that they are
set as desired.)
Gas Measurement Using a Calculated Divisor and Rate Multiplier
Calculating the divisor and rate multiplier for gases is necessary when registering in
units other than MCF and MCF/D. The
USEr volume and rate functions of the MC-II
Plus Flow Analyzer are used in this case. Each MC-II Plus Flow Analyzer is shipped
with a label set containing commonly used rate and volume units of measure labels.
The appropriate label can be placed on the front panel on the right side of the LCD
viewing window. The part number for the label set is listed in Appendix B in the
