Page 18: Memory Screen
5.7. MEMORY Screen The AEROCET 531S memory is composed of a single file which contains the data from sample events. Every time a sample is completed, the AEROCET 531S stores that data into the memory. The AEROCET 531S memory is circular, meaning when the memory is full, the unit will start overwriting the oldest saved samples with new samples. -
Page 19: Set Flow Screen
5.8. SET FLOW Screen The AEROCET 531S has a factory calibrated flow rate of 0.1 CFM (2.83 LPM). Use the following procedure to adjust the flow rate when a periodic flow rate check (Section 8.3) indicates a flow rate error greater than +/- 5%. -

Page 22: Commands
7.1. Commands AEROCET 531S provides serial commands for accessing stored data and settings. All commands are terminated by a carriage return. Also, these commands are not case sensitive. The following table lists the available commands. These commands are available via USB, RS-232 and RS-485 hardware interfaces. The settings (baud rate, parity and stop bits) must match the computer setting for proper communication regardless of the hardware interface type (USB, RS-232 or RS-485). -
Page 23: Real Time Output
The real time output occurs when the unit finishes a sample. The output format is either off (NONE), a comma separated value (CSV) or a printer (PRINTER) depending on the REPORT style settings (see section 5.4.3) AEROCET 531S Manual Page 22 AEROCET 531S-9800 Rev A.docx... -

8.4. Annual Calibration The AEROCET 531S should be sent back to Met One Instruments yearly for calibration and inspection. The annual calibration cannot be performed by the customer because this calibration requires specialized equipment and a skilled technician. Met One Instruments maintains a calibration facility for calibrating particle counters according to industry accepted methods such as ISO, JIS and NIST. -
