Using the Trend Graph

•

Up to 15 Components can
be plotted on the Trend
Graph

•

Click on

Ch

column and a

color will appear for this
gas on the Trend Graph

•

The 100% Y-axis = gas
measurement range.

Example :

•

Red gas = Methane

•

100% = 50 ppm

•

Black component (always
1

st

gas clicked) shows

time & gas concentration.
