Measure Type: Analog
Analog measurements involve reading a voltage or current provided by a sensor. Analog sensors
come with instructions that provide information on how to translate the output voltage into
desired units. Translating the analog sensor output into environmental units can be done via
slope and offset for simple sensors, and via equations for non-linear sensors.
Analog measurements are available on select models.
