YSI 3200 - Manual (Page 8)

Introduction Section 1
The 3200 has two main operating modes, Data and Operation. The current mode is displayed in
the dark bar at the top right corner of the display. The following diagram shows the typical
display while the instrument is in the Operation mode.

Message line
The bottom row of the display identifies the function of the four soft keys, which are located on
the keypad below the display. The function of each of these keys changes with each mode.
The [Mode] key and soft keys are used to navigate through the menus. The [Mode] key is used to
cycle between the two main operating modes. Pressing a soft key will bring up a new set of soft
key functions (menu). The [Mode] key is also used to backup through the menus to the top level.
The right side of the display shows the cell constant, temperature compensation data and current
temperature source.
K= 10.100 indicates that a single fixed cell constant of 10.100 is being used. K= would change to
Km= when using multipoint calibration.
25.0°C indicates that readings are temperature corrected to 25°C using a coefficient of 1.91%/°C,
as indicated just below on the screen. When non-linear temperature compensation is used, N.L. is
displayed here. When a standard non-linear curve is selected, the name of the curve (Pure,
Natural) is displayed here. When no temperature compensation is being used, these two lines of
the 3200 display are blank.
T CELL indicates that the temperature source is a conductivity cell with an internal temperature
sensor (YSI 3200 series). T PROBE is displayed when the temperature source is an external
temperature probe.
