This section contains an overview of the functionality of the Type TB82TE transmitter. FUNCTIONAL OPERATION The Type TB82TE transmitter provides a four to 20-milliampere output signal that is proportional to solution conductivity. The transmitter is compatible with all ABB two-electrode conductivity sensors. USER INTERFACE The user interface consists of a tactile keypad with four nondedicated smart keys and a custom LCD. The LCD has a three and one-half digit numeric region that displays the PV, a six-character alphanumeric region that displays secondary information and programming prompts, and several status-indicating and programming icons. Using a patent-pending novel approach, each of the four smart keys is located under a given set of icons. In each of the instrument modes and mode states, one icon over any given smart key illuminates and represents that smart key function. These smart key assignments vary as different programming modes and states are entered. In addition to the smart key assignments, text strings located in the six-character alphanumeric field (secondary display) are used as programming prompts. MODULAR ELECTRONICS The transmitter consists of three separate printed circuit board (PCB) assemblies that concentrate specific circuit functionality. This modular design allows for the ability to change the instrument from one of four types of instruments to another: pH/ORP/pION, four-electrode conductivity, two-electrode conductivity, and toroidal conductivity. In addition, instrument repair is made quick and easy by replacing the nonfunctioning PCB. TEMPERATURE COMPENSATION The process temperature is monitored using one of three types of RTD inputs: three-kilohm Balco, Pt 100, and Pt 1000. It is possible to program the secondary display to show the DESCRIPTION AND OPERATION DAMPING 2 - 2 WTPEEUI520002A1 temperature in degrees Celsius or degrees Fahrenheit when in the measure mode. Temperature affects the activity of the disassociated ions in solution and hence the conductivity of that solution. Therefore, manual and automatic temperature compensation functions are available. Temperature compensation functions for conductivity and concentration configurations include manual (0.1N KCl based) and six types of automatic compensation routines. The automatic types are: standard (0.1N KCl based), coefficient (zero to 99.9 percent per degree Celsius adjustable), user-defined, pure water neutral salt, pure water trace acid, and pure water trace base. DAMPING Input damping can be adjusted from 00.0 to 99.9 seconds. This feature is useful in noisy process environments. It helps minimize the displayed PV and output current bounce. Damping simulates a capacitive type lag where reaction to any signal change is slowed according to an entered time constant. For example, the output response to a step change in input reaches approximately 63.2 percent of its final value in five seconds for five seconds of damping. DIAGNOSTICS Diagnostics are provided for both the transmitter and sensor. Diagnostic detection of a serious condition that prevents the instrument from properly functioning enables a preset safe mode state. This configurable safe mode state forces the instrument output to be either high or low. Some problems do not keep the instrument from functioning. A diagnostic spike output feature is used for these conditions. Once enabled, this feature modulates the output for one second out of every six seconds. The magnitude of these modulations can be set from one to 100 percent of the maximum output. Detection of over 40 problem conditions can be enabled. In both cases, diagnostic conditions cause the FAULT and FAULT info icons on the display to energize. Interrogation of each fault condition is ava
