DOTX-45 Dissolved Oxygen System Part 6 – Configuration

DOTX-45 27 -

6.11 Keys

All user configurations occur through the use of four membrane keys. These

keys are used as follows:

MENU/ESC To scroll through the menu section headers or to escape

from anywhere in software. The escape sequence allows

the user to back out of any changes in a logical manner.

Using the escape key aborts all changes to the current

screen and backs the user out one level in the software tree.

The manual will refer to this key as either MENU or ESC,

depending upon its particular function. In the battery-

powered version of the DOTX-45, this is also the ON button.

UP (arrow) To scroll through individual list or display items and to

change number values.

LEFT (arrow) To move the cursor from right to left during changes to a

number value.

ENTER To select a menu section or list item for change and to store

any change.

6.12 Display

The large custom display provides clear information for general measurement

use and user configuration. There are three main areas of the display: the main

parameter display, the secondary message line, and the icon area.

Main Parameter During normal operation, the main parameter display

indicates the present process input with sign and units. This

main display may be configured to display any of the main

measurements that the system provides. During

configuration, this area displays other useful set-up

information to the user.
