LCD Display
The liquid crystal display ( Figure 1.2, page 11 ) provides a simultaneous indication of accumulated total
(top readout) and flow rate (bottom readout). The eight-digit total display uses 7-segment characters to form
numbers and letters, which results in a combination of uppercase and lowercase letters. The six-digit flow rate
display uses 11-segment characters to form numbers and letters for improved readability. When the keypad
is used to calibrate the MC-III Panel Mount, the name of the menu option selected appears in the lower (rate)
display, and settings are entered in the top (total) display.
Flow volume can be measured in barrels, gallons, liters, cubic meters, cubic feet, standard cubic feet or other
user-defined units. A multiplication factor is also available for indicating flow volume in terms of 1,000 units.
The unit of measure for the Total readout and the decimal point position are selected by the operator during
calibration. If a user-defined unit is used, none of the preprogrammed volume units will be visible on the
display during operation.
Flow rate can be measured in a wide variety of preprogrammed units, or other user-defined units. The flow
rate unit of measure is selected in two steps: (1) a volume unit is chosen and (2) a time-base unit (per day, per
hour, per minute, or per second) is chosen. Users can choose any combination of preprogrammed volume and
time units in establishing the flow rate engineering unit (for example, gallons per hour, gallons per day, or
gallons per minute). Also, the volume unit used for the flow rate can be different from the volume unit used to
read Total volume. The unit of measure for the Rate readout and the decimal point position are selected by the
operator during calibration.
The daily index (Day) display is a two-digit number for selecting a daily archive log for viewing. The number
shown here represents the number of days that have passed since the log was saved. For example, an entry of
01 would yield yesterday’s log. An entry of 05 would yield the log generated 5 days ago. Up to 99 consecutive
daily logs can be viewed using the keypad. In addition, up to 384 daily logs, 768 hourly logs, and 345 event
logs can be viewed through the interface software.
The LCD contrast can be adjusted with the interface software (see
Section 4 ).
Keypad
The six-button keypad allows users to perform a basic configuration of the instrument.
Figure 1.3, page
11 , summarizes the functions that can be accessed with each button. Most parameters can be configured in
seconds by selecting one of the three menu keys (K-Factor, Output, or Display), navigating settings with the
arrow buttons, and saving the selections with the Enter key.
Section 3 contains procedures for configuring the MC-III Panel Mount using the keypad. Icons of the six
buttons provide a pictorial reference to help guide users through each step of configuration.
Important: Some configuration parameters are accessible only through the interface software. See
Section 4
for instructions on configuring the instrument using the software.
