See explanation below... Explanation: The temperature output is scaled to 1.00 mV/K, but it isn't specified (and indeed, is highly improbable!) that 0.00 mV = 0 K (absolute zero!) By offsetting the output voltage against the fixed reference voltage (in external circuitry), you can set the output to suit any desired temperature scale — 0C is not equal to 0°F which is not equal to 0 K either, so there has to be some correction in order for the reading to be appropriate for the wanted scale. The 2 parameters you usually change to scale such an output would be gain and offset. I hope that helps! It's a little difficult to understand exactly what part you didn't follow? |
