MIE ADR-1500 Instruction Manual
The ADR-1500 has five modes of Operation:
1. Start-up. This is accomplished by holding the ON/OFF key for 4
seconds whereby the splash screen will appear.
2. Run Mode. This is when the instrument is measuring aerosol and
operating with an active flow rate. Normally the instrument is set for
data logging to be enabled in this mode.
3. Standby. This is when the instrument is in an idle mode during which
the user is interfacing with the instrument menu, configuring the
instrument, downloading data, calibration, or when the instrument is
set to begin sampling via an auto-start.
4. Zeroing. This mode is used to establish the optical background
(Rayleigh scattering) of the ADR-1500. During this mode of operation
the user is required to install a zeroing tube that connects the inlet stem
to a HEPA filter.
5. Shutdown. Accomplished by holding the ON/OFF key until text on
screen is no longer visible. The instrument is off.
