6.0 OPERATION DETAILS
6.1 Basic Operation
To operate the PQ100 Air Sampler, press the Power "On/Off" pushbutton keyswitch. The
unit will beep a few times and display;
BGI PQ100 Air Sampler
and briefly, the unit serial number and firmware revision;
SN:1234 Version 5.23
and then;
Initializing!
During the power-up sequence if it has been determined that the unit had previously
shutdown due to one of the shutdown conditions, i.e. "Flow Rate Error", "Low Batteries",
"Sample Run Completed" etc. the unit will then flash one of these messages at the display
and requires that the user press the "Enter" key to continue on to the MAIN IDLE
DISPLAY (See APPENDIX E for a description of all shutdown codes). If the unit was
powered down normally, i.e. the power "On/Off" key was previously pressed while at the
MAIN IDLE DISPLAY, then it will jump from the above initialization messages directly
to the MAIN IDLE DISPLAY and will not display a flashing error message.
