TE-CD-TSP 71 Operations Manual
The “Avg Amb Pressure” line reports the average ambient pressure (aka true barometric pressure) and is
reported in mmHg.
The “Flags” line reports any items that may be of importance in determining the validity of the data.
The individual flags are separated by commas. The possible flags are POWER (which indicates a power
failure or brown out occurred during the sampling), ABORTED (which indicates the sampling was
aborted by user interaction with the timer), FLOW (which indicates the flow rate exceed the set flow
rate by +/- 10 percent for a period greater that 2 minutes) and EXPIRED (which indicates the sampling
never occurred, likely because the unit was without power for the entire test).
