.3.5 Troubleshooting
If a problem is suspected, check the sensor cable. Disconnect the connector
and use a digital volt meter (DVM) to check the resistance between Pin A
(sensor signal) and Pin C (sensor ground). The resistance should read as an
open circuit until you move the rain gage tipping mechanism where the magnet
swings past the reed relay. Try connecting a substitute sensor. Obtain an
RMA number before returning this sensor to Campbell Scientific for repair.

4.4.1 General Description
The Apogee Pyranometer (pn CS300-QD) shown in FIGURE 4-3 measures
incoming solar radiation with a silicon photovoltaic detector mounted in a
cosine-corrected head. The detector outputs current; a shunt resistor in the
sensor converts the signal from current to voltage. During the night, the
CS300-QD may read slightly negative incoming solar radiation. The negative
signal is caused by RF noise.
