OPERATION AND MEASUREMENT

Connect the sensor to a measurement device (meter, datalogger, controller) capable of measuring and displaying
or recording a millivolt signal (an input measurement range of approximately 0-40 mV is required to cover the
photon flux density range the sensor is capable of measuring). In order to maximize the measurement resolution
and signal-to-noise ratio, the signal input range of the measurement device should closely match the output range
of the ePAR sensor.
