5.3.1. Units The Units setting allows the volume and temperature units to be selected. Volume: The AEROCET 532 supports total counts per timed sample (TC), particles per liter (/L), particles per cubic foot (CF), and particles per cubic meter (M3). Particle count information updates while the unit is sampling. -
Page 17: Memory
5.3.2. Memory The AEROCET 532 can store up to 15,000 sample records in its memory. For instructions on viewing stored data, see section 4.3.3. Because this memory is circular, once all 15,000 records are full, any new samples taken will overwrite the oldest stored sample data. -
