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 entire range of

UV from the sun). In order to maximize measurement resolution and signal-to-noise ratio, the input range of the

measurement device should closely match the output range of the UV sensor. DO NOT connect the sensor to a power

source. The sensor is self-powered and applying voltage will damage the sensor.

VERY IMPORTANT:

Apogee changed all wiring colors of our bare-lead sensors in March 2018 in conjunction

with the release of inline cable connectors on some sensors. To ensure proper connection to your data device,

please note your serial number or if your sensor has a stainless-steel connector 30 cm from the sensor head then

use the appropriate wiring configuration below.
