The divisor and rate multiplier are entered in the same manner as the divisor and
rate multiplier were entered in the
Liquid Measurement Using a Calculated Divisor
and Rate Multiplier example.
Time Out Feature
The MC-II
Plus Flow Analyzer has a Time Out Feature, which prevents it from being
left in the Calibrate Mode indefinitely. If the MC-II Plus Flow Analyzer is left in the
Calibrate Mode and no keypad activity is seen for approximately 10 minutes, it will
return to the Run Mode. If the unit is in Calibrate Mode and a Time Out occurs, any
data that has been input with the ENTER key being pressed afterward will be saved
to memory. Any data that has been input without the ENTER key being pressed
afterward will not be saved when Time Out occurs and the data entered from a
previous calibration will be retained.
Presetting Volume
Typically when a new flow analyzer is placed in service, the accumulated volume will
start at 0. In some applications where an existing piece of instrumentation is being
replaced, it is preferable to resume the volume where the former instrument left off.
The MC-II
Plus Flow Analyzer has the capability to accept a preset volume. The
volume unit of measurement (BBL, GAL, etc) and the decimal position for the
volume (0.0, 0.00, etc.) must be defined prior to presetting the volume.
The steps required to preset a volume are:
1. Enter the calibration mode by pressing the ACCESS key.
2. At the prompt tot Eng , press INCR to select BBL, GAL, M³, MCF or USER.
Press ENTER .
3. At the prompt tot d.P , press INCR to change the decimal point position for the
volume. Press ENTER .
4. At the prompt SEt tot , press INCR to toggle between yES or no until yES is
selected. Press ENTER .
5. At the prompt SEt.tot , use INCR and STEP to change the volume. The
currently selected volumetric unit of measure will be displayed and the current
decimal point will be indicated. Press
ENTER .
6. At this point, the volume has been preset. Pressing ACCESS exits the
Calibrate Mode without making any further changes, or the remaining steps
may be implemented.
