Section 9

Maintenance

DANGER

Explosion hazard. Only qualified personnel should conduct the
tasks described in this section of the manual.

DANGER
Electrostatic hazard. Follow the instructions in

Electrostatic

Discharge (ESD) Considerations on page 20

before conducting

any maintenance tasks.

9.1 Cleaning the instrument

Use only a moistened antistatic, lint-free cloth to remove dust, dirt and
spots from the external surfaces of the transmitter. Use a mild
household cleaner if necessary.

9.2 Sensor maintenance

Refer to the user manual supplied with each sensor for specific
cleaning requirements.
