APPENDIX E. SHUTDOWN MESSAGES
The following is a description of the various messages that can be displayed by the PQ100 or the
PQ Software to indicate the reason for sample job termination or current status of the PQ100;
00 Download not yet Appended! PQ Software
* Indicates that a previously created job file has yet to receive a download from a PQ100
Sampler.
01 LOW BATTERY SHUTDOWN! PQ100
Low Batteries! PQ Software
* Indicates that the sample job was terminated when the battery power had been depleted
and should now be recharged.
02 SAMPLE RUN COMPLETED! PQ100
Run Completed! PQ Software
* Indicates that the sample job was terminated when the RUN TIME had been depleted
(See Section 6.7 or Section 6.8.3).
03,04 FLOW RESTRICTED! PQ100
Flow Restricted! PQ Software
* Indicates that the sample job was terminated due to a flow rate transient of 50% of the
target flow rate and is usually caused by a kinked or broken hose, filter load removal etc.
During the initial time that the PQ100 requires to stabilize its flow rate, flow will be
displayed as --.-Lpm. During this stabilization period, flow rate is allowed to vary more
than 50% for a maximum of one minute. After one minute the flow is considered
restricted causing the above shutdown. Once the flow rate has stabilized, the flow rate
will appear and response to transients greater than 50% is instantaneous.
05 Counters Reset, Awaiting new Run! PQ Software
* Indicates that the PQ100 has been "Reset" and is now ready for a new sample job.
