VI What the Gas-Tec shows

6.1 Overview

Gas-Tec makes it easy to pinpoint gas leakages so that they can be dealt with quickly . The data can be
checked while recording is taking place, or loaded down later .
To find information about the location of the Gas-Tec at a particular time, and other basic aspects of the
system, use the 'Info' soft key at any time during operation . A choice of screens is provided: 'System' and
'GPS' .
A record of the concentration of hydrocarbon gases encountered by the probe as it is carried by the opera-
tor is stored in date-stamped files in an internal memory . Data is registered every second and is recorded
against the time the record is logged . The built-in GPS, (if locked), allows the position to be logged at the
same time .
To upload the data, plug the detector's USB connector into a PC (the green led will light on the Gas-Tec
when connected) . Gas-Tec will be recognised as a memory device, and a folder will open displaying log
files in date order .
The files can be manipulated or sent via e-mail to interested parties .
The data collected by Gas-Tec includes:
Column A Count
Column B Time
Column C Absolute
Column D Relative
Column E Latitude
Column F Longitude
Column G Height
Column H SOG
Column I COG
Column J Mark
In addition, each report includes the serial number of the Gas-Tec used for the survey .
