If this option is not selected the results will be display as decimal degree. Note that functions will return angle values in radians and will have to be converted to degrees in the formula by multiplying result by (180/Pi).

  • Page 47: Definitions

    Definitions Absolute is the part size displayed as a whole number. An A/E (Air to Electric) transducer converts changes in pneumatic pressure into an electrical signal. LIVE is a function that displays the reading as a constantly changing value in real time.
  • Page 48 Definitions - continued Polarity is the (+) or (-) indicator applied to the magnification of an input to correctly display that reading based upon the direction the input value changes. In +PEAK (or -PEAK) modes display the largest or smallest size reading seen during the movement of the part after it has been reset.
