8 TROUBLE

SHOOTING



The following contains a procedure for checking the instrument in
case it appears that it does not function as one could expect.

Trouble shooting:

Output signal fails or shows improbable results:

ƒ Check the wires, whether they are properly connected to the

readout equipment.

ƒ Check the dome and the drying cartridge, they 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.

ƒ Check the instrument impedance (500 - 2000 Ohm)
ƒ Check datalogger or integrator offset by connecting a dummy

load (500 - 2000 Ohm resistor). This should give a “zero”
reading.


If water or ice is deposited to the outside of the dome, clean the
dome. Usually 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.
