START SURVEY
Use of GPS (Optional)
After switching the instrument on, the GPS will not be active.
The integral GPS allows the user to save the measured gas level with current GPS coordinates. The
available memory installed in the instrument will give the user the facility to store a full day of
measurements, it can record up to 8 hours. The GPS information is stored every second.
Note: Data is only acquired and saved when the GPS is active.
NB: ---- % means that the instrument is not logging.
GPS Activation
To activate the GPS, press the Jogdial and rotate the dial to
scroll through the menu options until “ON/OFF GPS”
appears. Press the jogdial to confirm the selection. The GPS
icon will change status from “Off” to “Active”.
The percentage of memory used will also be displayed in
the bottom left-hand corner.
Initially, only the percent symbol, (%), will be displayed. Once the GPS has stabilized and the LASER
ONE begins saving data, a number will appear next to the percent symbol to indicate what
percentage of the memory has been used.

The GPS module is a high-performance receiver with the ability to track up to 20 satellites. The
antenna is a standard, high gain, vehicular type that provides quality tracking performance.
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 obtain a fix in less than a minute.
Note:
In the event of signal loss during the survey, the instrument will continue to log gas values and will
associate the last saved tracked GPS position.
