An electronic measurement, data storage and readout system utilizing a programmable processor and controller to manipulate data measurements from a transducer is disclosed. Means are provided for electronically safeguarding the stored data. In the preferred embodiment means are also provided for reading out the data directly to a dedicated printer for producing graphical representations of the data and for converting the data to frequency-shift keyed signals which can be transmitted over telephone lines to the dedicated printer. A redeployment station is provided to reinitialize the programmable processor and controller.

A low power consumption, electronic monitoring and data storage system for remote monitoring of a condition over a period of time, comprising: a transducer for generating an analog output signal indicative of the condition to be monitored; an electrically powered converter operatively associated with the transducer to convert the analog signals to digital signals; a memory for storing the digital signals as stored data; a clock pulse generator for generating clock signals at a first frequency; processing and controlling means, responsive to the clock signals, for processing the digital signals and for controlling the memory so that the digital signals representing the monitored condition at selected intervals during the time period are stored in the memory at selected time intervals, including means for reading out the stored signals at a later time and to provide a historical report of the monitored condition wherein the processing and controlling means is responsive to an externally applied second clock frequency signal, substantially different from the first clock frequency, to initialize the system so that the system will not record data beyond a selected time period without being initialized by a designated user to control use of the system by other users.
