Abstract: The disclosure is of a remote process sensor and signal transmitter including apparatus for configuring the sensor and transmitter to perform various functions. The transmitter includes a program and apparatus for cycling through the program and the system microprocessor to set into the transmitter various conditions including its temperature range of operation, one of many possible remote temperature sensors and other operating states. The program includes two portions each of which can be entered by a switch. Each portion of the program can be cycled through and as selected portions of the program are reached, a selected parameter can be set into the microprocessor as a permanent operating condition. The set operating conditions can be set or reset at any time by cycling through the program in accordance with the set protocol.
