MAINTENANCE
1) REMOVE POWER FROM THE POWER SUPPLY
TERMINALS AND FROM RELAY OUTPUT
TERMINALS
2) Remove the instrument from case.
3) Using a vacuum cleaner or a compressed air jet (max.
3 kg/cm 2 ) remove all deposit of dust and dirt which may
be present on the louvers and on the internal circuits
trying to be careful for not damage the electronic
components.
4) To clean external plastic or rubber parts use only a
cloth moistened with:
- Ethyl Alcohol (pure or denatured) [C
2
H
5
OH] or
- Isopropil Alcohol (pure or denatured) [(CH
3
)
2
CHOH]
or
- Water (H

O)
5) Verify that there are no loose terminals.
6) Before re-inserting the instrument in its case, be sure
that it is perfectly dry.
7) re-insert the instrument and turn it ON.
