  1. The over- or under-range flag comes on when the normal operating range (over/under) is exceeded. The module continues to convert the analog input up to the maximum full scale range. 
    The flag automatically resets when within the normal operating range.
  2. Step response is the time between when the D/A converter was instructed to go from minimum to full range until the device is at 63% of full range.
  3. Includes offset, gain, nonlinearity, and repeatability error terms.
  4. Output ripple is the amount that a fixed output varies with time, which assumes a constant load and temperature.
  5. Repeatability is the ability of the input module to register the same reading in successive measurements for the same input signal.
  6. Rated working voltage is the maximum continuous voltage that can be applied at the input terminal, including the input signal and the value that floats above ground potential. 
    For example, a 10V DC input signal and 20V DC potential above ground at the input terminal.
  7. If the optional 24V DC Class 2 power supply is used, the 24V DC current draw from the bus is 0 mA.
