Icon Key Function

Exit to MEASURE Escapes back to the Measure Mode from all other modes or programming states of operation.

This function is not available in the Measure Mode.

FAULT Info Accesses information on diagnostic problem or error conditions. Displays this information as a

short text string and code. This function is only available in the Measure Mode.

SELECT Selects the mode or programming state of operation shown in the secondary display region.

ENTER Stores configured items and data into memory.

NEXT Increments through a series of programming states.

YES Affirms the action that is about to take place.

NO Denies the action that is about to take place.

MENU Increments through the modes of operation.

Increases numeric values or moves through a series of parameters.

Moves the flashing data entry value one space to the right.

Decreases numeric values or moves through a series of parameters.

Mode Function

Measure Used to display the process and secondary variables – the normal operating mode for the

transmitter.

Calibrate Used to calibrate input devices (i.e., the process and temperature sensors).

Out/Hold Used for viewing critical parameters found in the Transducer and Analog Input Function Blocks.

Configure Used to configure transmitter functions such as temperature compensation, temperature sensor

type, and measurement electrode type.

Security Used to enter password protection for the Calibrate and Configure Modes of Operation.

Display Used to select the variable that will be shown in the secondary display region when the

transmitter is in the Measure Mode of Operation.

MEASURE MODE

The Measure Mode is the normal operating mode of

the transmitter. In this mode, the process variable,

fault conditions, and secondary display information

are displayed. From the Measure Mode, other modes

of operation and fault information can be accessed.

When a user enters an operating mode or state and

does not return to the Measure mode as the final

step, the transmitter automatically returns to the

Measure Mode of operation after 20 minutes of

unattended use.

The process variable is shown in the primary display

area. The value of this variable is dependent on the

configured analyzer, temperature compensation type,

temperature value, and sensor signal. The

engineering units for the process variable are

dependent only on the configured analyzer. The table

below lists the analyzer types and corresponding

engineering units.

Analyzer Type Engineering Unit

Conductivity

mS/cm, µS/cm

Concentration ppm, ppb, %, User

Defined Text, No Units

The secondary display has the ability to show a large

variety of information. Since the display area only has

six characters, only one item can be shown at any

given time. Typically, this region will be used for

displaying the process temperature in degrees

Celsius; however, it can be changed to display the

process temperature in degrees Fahrenheit, sensor

group, sensor type, conductivity value and solute

name for a concentration analyzer type, and firmware

revision.

Fault information can only be accessed from the

Measure Mode. During a fault condition, the FAULT

warning icon above the process variable display

region will blink. The FAULT Info key will also

become active and can be used to obtain a text

description of the fault condition. Pressing the FAULT

Info key progressively moves from one fault to the

next until all faults have been shown. Once all faults

have been interrogated, the FAULT icon stops

blinking and will remain energized until all faults have

been removed. If a new fault condition is detected,

the FAULT icon will begin to blink to inform the user of

the newly detected condition.

The MENU key provides access to all other modes of

operation. Pressing this key moves the transmitter to

the next operating mode. Visual feedback is provided

in two manners: the mode indication arrow moves to

the next mode of operation (e.g., Calibrate) and the

secondary display shows the text string representing

the new mode of operation (e.g., CALIBR).
