8. 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 are properly connected to the readout equipment.
-
Check the dome, it should be clear and clean. If water is deposited on the inside, please change the
desiccant. If too much water is deposited internally the drying cartridge should be removed and the
instrument warmed to dry it.
-
Check instrument impedance (see specifications for expected values).
-
Check data logger or integrator o set by connecting a dummy load (100 Ohm resistor). This should
give a 'zero' reading.
-
Check levelling (bubble inside ring).
If water or ice is deposited on the dome, clean it. Probably water droplets will evaporate in less than one
hour under sunlight.
Any visible damage or malfunction should be reported to your distributor, who will suggest appropriate
action.
