Maintenance and Service
Thermo Fisher Scientific MIE ADR-1500 Instruction Manual 5-7
Although the ADR-1500 incorporates an aerodynamic inlet to optimize
aerosol delivery through the sensing chamber, continued sampling of
airborne particles at high concentrations may result in gradual build-up of
contamination on those interior surfaces of the sensing chamber
components. This may cause an excessively high optical background level.
If this background level does become excessive, the ADR-1500 will alert
the user at the completion of the zeroing sequence. If this message is
presented, the ADR-1500 can continue to be operated providing accurate
measurements only if the background can be reduced. This “might” be
possible by blowing a stream of compressed filtered air through the optical
chamber and re-zeroing.
Equipment Damage If unsuccessful, the instrument must be sent back to
the factory for service. ▲
