SECTION 1 - USER INTERFACE

Model P33 pH/ORP Analyzer (panel-mount 1/4 DIN)

Rev. 6-1100

ENTER key:

Pressing this key does two things: it dis-

plays submenu and edit/selection screens, and it enters
(saves) configuration values/selections.

ESC key:

Pressing this key always takes the display up

one level in the menu tree. (Example: With any “MAIN
MENU” screen displayed, pressing the

ESC key

once

takes the display up one level to the MEASURE
screen.) This key can also “abort” the procedure to
change a value or selection.

and

keys:

Depending on the type of displayed

screen, these keys do the following:

•

MEASURE Screen: Changes readout (in continuous

loop sequence) to show different measurements.

•

Menu Screens: These keys are non-functional.

•

Edit/Selection Screens: “Coarse” adjusts the

displayed numerical value.

and

keys:

Depending on the type of displayed

screen, these keys do the following:

•

MEASURE Screen: These keys are non-functional.

•

Menu Screens: Moves up or down respectively

between other same-level menu screens.

•

Edit/Selection Screens: “Fine” adjusts the displayed

numerical value (holding key down changes value
faster), or moves up or down between choices.
