OPERATION AND MEASUREMENT

Connect the sensor to a measurement device (meter, datalogger, controller) capable of measuring and displaying

or recording a 4-20 mA signal. 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 pyranometer. DO NOT connect the

sensor to a power source greater than 24 V DC.

VERY IMPORTANT:

Apogee changed the wiring colors of all 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 listed below. With the switch to connectors, we also

changed to using cables that only have 4 or 7 internal wires. To make our various sensors easier to connect to

your device, we clip off any unused wire colors at the end of the cable depending on the sensor. If you cut the

cable or modify the original pigtail, you may find wires inside that are not used with your particular sensor. In

this case, please disregard the extra wires and follow the color-coded wiring guide provided.
