SEM5000 Surface Emissions Monitor
NOTE: The GPS module is a high-performance receiver with the ability to track up to 20
satellites.
Start up time for the GPS module can vary according to the strength of the actual signal
received.
The presence of high trees or buildings, aerial power lines or other obstructions will affect
the signal. Typically, in an open area, the GPS will fix in 1 to 3 minutes.
In the event of signal loss during the survey, the instrument will continue to log gas values
and will associate the to the last saved tracked GPS position until the signal is reacquired.
SEM5000 Set Up
