Appendix A: Operation at High Air Humidity and/or Low Measuring Temperatures

Appendix A: Operation at High Air
If the ambient air contains humidity and the measuring temperature is lower than
the ambient temperature, condensation may occur in the measuring cell and
measuring cell block. Condensation in the measuring cell causes adjustment and
measurement errors. Condensation in the measuring cell block damages the
electronics.
Preventing condensation in the measuring cell
To prevent condensation in the measuring cell, use a drying cartridge connected
to the "DRY AIR PUMP" nozzle at the rear of the DMA. The drying cartridge
provides dry air for a thorough drying of the measuring cell .

Important:
Never connect hoses containing liquids or moist gases to the "DRY AIR
PUMP" nozzle as this may lead to condensation in the measuring cell.
