CNR4 Net Radiometer

FIGURE 6-2. The marks on the end of the CNR4: S for SOLAR cable,

and T for TEMP cable.

The measurement details for Pt-100 sensor, including the wiring diagram and

sample program are explained in the Appendix C of this manual.

The four radiation outputs can be measured using differential or single-ended

inputs on the datalogger. A differential voltage measurement is recommended

because it has better noise rejection than a single-ended measurement.

When differential inputs are used, jumper the low side of the

input to AG or to keep the signal in common mode range.

NOTE

The Tables 6-1 and 6-2 show the wiring instructions for the differential

measurement and single-ended measurement connections to the datalogger,

respectively. The cables have the white band at the pigtail end of the cable

with the color keys. See the Figure 6-3 and 6-4 below for the labels on the

cable for both the SOLAR and TEMP cables.
