Table 1—MC-II Keypad Functions
RUN MODE FUNCTIONS
ENTER/STEP
Saves current volume total in nonvolatile memory.
RESET Allows user to zero the volume.
VIEW DIV Displays the current calibration factor.
DEC. POINT Changes the position of the decimal point in the TOTAL (top) display.
INCREMENT
Adjusts the LCD contrast.
CALIBRATE MODE FUNCTIONS
ACCESS Places the MC-II in the Calibrate Mode and permits you to perform the following tasks:
Set units of measure for the TOTAL (top) display.
Set the calibration factor.
Set the units of measure for the RATE (bottom) display.
Select or deselect the pulse output option.
Select or deselect the password-protected security option.
Preset a total. (If an MC-II must be replaced, the user can enter the volume from the previous analyzer and
prevent the loss of this data when the volume count resumes. See Step 7 of the calibration procedure on
page 16.)
SHORTCUT: Press and hold ACCESS for 3 seconds, then release to accept an existing NUMERICAL
calibration setting and advance to the next menu option. This shortcut is applicable to NUMERICAL data fields
only.
DEC. POINT Moves the position of the decimal point when entering numerical data such as a calibration factor.
INCREMENT Scrolls/toggles through available settings for each menu option, and allows the user to change the flashing
digit when inputting numerical settings. A single press advances digits/text entries to the next available setting.
Depressing and holding the INCREMENT key scrolls through all digits.
ENTER/STEP Accepts the calibration setting shown on the display and advances to the next data entry position (flashing digit
field) or menu option.
RESET Allows the user to re-enter a numerical value in the bottom display (if the value has not been accepted by
pushing the ENTER/STEP button. To re-enter the value, press and hold RESET for 3 seconds, then release.
The right-most digit will begin flashing, allowing the user to re-enter the value, right to left.
View Calibration Factor
Press
VIEW DIV
key at any time during the Run mode to view the current calibration
factor. If the MC-II is programmed to display a preprogrammed unit, the calibration fac-
tor will be displayed in pulses per gallon, and the abbreviation PuP.gAL will appear in
the top LCD window.
If the MC-II is programmed to display a user-defined unit, “uSEr” will appear in the top
LCD window, and a calculated divisor will be displayed in the bottom window. See “Ex-
ample: Liquid Measurement with User-Defined Units of Measure” on page 20 for more
information.
