TROUBLE SHOOTING
The following contains a procedure for checking the instrument in case it
appears that it does not function as it should.
Trouble shooting:
Output signal fails or shows improbable results:
Check the wires, whether they are proper connected to the readout
equipment.
Check the instrument location. Are there any obstructions that cast a
shadow on the instrument by blocking the direct sun during some part
of the day.
Check the window, it should be clear. If water is deposited on the
inside, please change the desiccant. If too much water is deposited the
instrument should be dried internally.
Check instrument impedance (700 – 150 Ohm)
Check data logger or integrator offset by connecting a dummy load
(700 – 1500 Ohm resistor). This should give a "zero" reading.
If water or ice is deposited to the outside, clean the outside. Probably water
droplets will evaporate in less than one hour.
Any visible damage or malfunction should be reported to your dealer, who will
suggest appropriate action.
