The analog output parameters comprise the scale factor and the offset. The scale factor corresponds to the physical unit per Volt (unit/V) output by the system, while the offset corresponds to the physical value at which the user wants the analog output to be at zero volt. For example, with a scale factor set to 10 °C / V and the offset set to 5 °C, the temperature as a function of the analog output voltage is given by:

Temperature = [Voltage output] x 10 °C / V + 5 °C

The default value of the scale factor is 50 °C / V (or its equivalent in °F) and the default value of the offset is 0 °C (or its equivalent in °F).

During a No Signal condition, constant values are output as follows: analog output value = 0 Volt,  RS-232  serial ports = 65 536.0.
