This section contains instructions for periodic cleaning and inspection of the instrument as preventative maintenance
measures. It also contains specific cleaning procedures to be conducted after disassembly. Parts having identical

Interior Cleaning
Printed Circuit Board Cleaning
The printed circuit board assemblies in the ELI 150 system contain static sensitive devices. Use special handling
procedures to prevent damage due to ESD.
Clean assembled parts with a vacuum cleaner or low pressure compressed air (30 psi). Take care when cleaning
printed circuit boards that wires or component leads are not bent back and forth in such a manner as to weaken them
and cause them to eventually break.
Dry with low pressure compressed air.
WARNING
Ventilate work area thoroughly when using solvents. Observe manufacturers warnings on
solvent containers with regard to personnel safety and emergency first aid. Be sure that first
aid equipment is available before using chemicals. Observe all shop safety and fire
precautions.
