5.3.3 Interpret measurement status
A "Good" or "Bad" status next to a value is an indication of the reliability or integrity of the
data being received, not an indication of whether or not the value is within the configured
upper or lower ranges. A value that triggers an alert, such as a high or low temperature
indication, will change the overall status of the device, but the measurement might still be
indicated as "Good" if the reliability of the data is good.
