  <p><strong>Shape</strong> tells you the number of dimensions to the array. A 
    [12x12] shape indicates a two dimensional array such as a VE table. A [12] 
    is a one dimensional array such as the x or y axis table data for MAP and 
    rpm. The tables start on the lower left going from left to right and up. See 
    the example VB program for creating a table.</p>
  <p><strong>Units</strong> are the human readable units. ADC means the value 
    from the analog to digital converter before they are scaled. ADC units typically 
    represent 0-5V max using 0-255 </p>
  <p align="left">The scaling is done with a multiplier (<strong>scale</strong>) 
    and an offset (<strong>translate</strong>) to get to user units (in the above 
    example AFR) use this formula: <br>
    userValue = (msValue + translate) * scale.</p>
  <p align="left"> The<strong> lo</strong> and<strong> hi</strong> value indicate 
    the range of the values. In this example for an input of 0-5V (Innovate 0-5V 
    LC-1) the user units will range from an AFR of 10 to 20. The scaling values 
    will be different for different sensor settings. </p>
  <p>The <strong>digits</strong> indicates the number of useful digits after the 
    decimal point. </p>
