Numeric Display
The
Numeric
display is the default display and one of the simplest screens for
go/no-go decisions based strictly on gas concentration measurements. Sample
gas is measured in parts per million (ppm). The resolution unit auto-adjusts. Figure
26 shows an example of a GLA131-GGA numeric readout of the last measurements
of CH
4
, H
2
O, CO
2
, CH

(Dry), and CO

(Dry) in parts per million (ppm). The displayed
numeric readout may vary, depending on the analyzer type. In addition, the
analyzer color-coded operational status is indicated (for details on color coding,
refer to
Alarm Status Display
).

Spectrum Display
The sample
Spectrum
display provides additional information on the measured
gas: the analyzer sensitivity level shown in the Transmitted Intensity diagram,
absorption level, theoretical fit of the targeted gas, and ringdown time indicating
the need to clean the high-reflectivity mirrors.
