Instrument Controls
The front panel of the 3624 ProBrix Plus
instrument has several displays and controls.
The Power Switch and Pump Switch are used
to turn the instrument or pump on/off respectively.
The
CO
2
and °brix-%diet LED displays are
driven by analog outputs from the instrument.
The
Key Switch should be turned to the
horizontal unlocked position to start the
instrument in measurement mode. The function
keys are only active if the key switch is in the
unlocked position. Use the vertical locked position
to avoid accidental modifications.
The
Display has a two-line liquid crystal display
(LCD) with 16 characters per line.
A
Light Button , when pressed, provides
illumination to the LCD for three minutes.
Four Function Keys provide simple operator
control over the instrument functions:
• ESC jumps back a step within a program
menu.
• The × Ø keys are used to scroll through
screen displays.
• ENTER selects a highlighted item from
the menu.
Main Menu
The operator controls the instrument by menu-
selectable commands using the four function
keys. The main menu has three choices:
• MEASURE to start the measurement
sequence.
• OPTIONS to enable the instrument to be
customized.
• CALIBRATE to provide a choice of
sensor calibration procedures.
To select one of these commands, first press ESC
until the main menu is displayed (as illustrated
above), next press the
× Ø keys until your choice
is flashing, and then press ENTER .
Entering Values
When entering numbers in any of the instrument
menus, the current numerical value is displayed
with one digit highlighted by the
^ symbol below it.
Use the × Ø keys to increase/decrease the value
of the digit (0-9 plus a decimal point) until you
reach your required target value.
Press
ENTER to shift the highlight symbol one
digit to the right and repeat the process. Pressing
ENTER after the last digit saves the value.
