power to sensor

•

correct connections

•

tight connections

•

no kinks in harness

Symptom: Radiation Value is -9999 or 0

•

Disconnect sensor leads and use a digital voltmeter

(DVM) to check voltage between the red, positive (+)

and black, negative (-) wires. Voltage must be 0—200

mV for 0 to 1000 W/m

radiation. No voltage indicates

a problem with either the photodiode or shunt resistor,

which are potted in the sensor head and cannot be

serviced.

Ensure that sensor head surface is clean and sensor is

level.
