SECTION 2 OPERATION
2.1 Operating the User-Programmable Setup
The EC1000 Controller is a menu-operated instrument. In the setup menu, each of
the instrument settings are grouped into submenus of common settings. For user
programming, move to the desired setting, and edit the current value. Refer to
Table 18 on page 99, which describes operation of the Diagnostic Test Menu.
2.1.1 Moving Around the Menu
After pressing the
SETUP
key to enter the menu, use the
UP
and
DOWN ARROW
keys to
scroll through the top level menu to the desired entry. Use the
ENTER
key to move down
into a submenu (use the
CLEAR
key to back up to the next higher menu level). Once the
desired setting is displayed, press the
ENTER
key to display the current value of the setting,
and change the value as needed. (Exit the menu at any time by pressing the
pH/mV
key.)
Example—checking or changing the ALARM2, SET PoiNT:
1. Press
SETUP
to enter the SETUP menu.
2. Press
ENTER
to move into the ALARMS submenu.
3. Press the
DOWN ARROW
key to scroll to the ALARM2 entry.
4. Press

5. Press the

2.1.2 Editing a Setup Value
Two types of setup data require editing. The first is a number entry such as an alarm set
point. Any value in the set point range can be entered. When the number entry is selected
first, the first digit space displays a flashing
+
or
–
sign character. Pressing the
UP
or
DOWN
ARROW
key alternates between the two signs. Pressing the
RIGHT ARROW
key moves to
the first digit. This digit flashes indicating that it can be edited. Pressing the
UP ARROW
key increases the digit value, and pressing the
DOWN ARROW
key decreases the digit value.
The remaining digits are changed by repeating this process. When the whole number is
changed to the desired value, press the
ENTER
key to save the new value. At any time
during the editing process, the original value is restored by pressing the
CLEAR
key.
