The firmware for the detector head is common to both CO
2
and HC instruments. This
feature allows the type of sensor fitted to be selected.
IMPORTANT
The instrument supplied with this manual has either an infrared HC sensor or an
infrared CO
2
sensor installed.
Changing the setting within this menu will not change the gas to which the
sensor is sensitive.
This menu option allows the sensor type to be selected. The available sensor options
are listed below:
OPTION TYPE RANGE COMMENTS
CH4L Infrared 0-100%LEL Methane
CH4t Infrared 0-100%LEL Methane
CH4H Infrared 0-100%Vol Methane
HC Infrared 0-100%LEL General hydro carbons
HCtC Infrared 0-100%LEL General hydro carbons
HCC Infrared 0-100% LEL General hydro carbons
HHC Infrared 0-100% Vol General hydro carbons
HHCC Infrared 0-100% Vol General hydro carbons
CO2L Infrared 0-5%Vol Carbon Dioxide
CO2t Infrared 0-5%Vol Carbon Dioxide
CO2H Infrared 0-25%Vol Carbon Dioxide
CO2P Infrared 0-10000 ppm Carbon Dioxide
ACET Infrared 0-100%LEL Acetone
The sensor type is selected as follows:
•
From the menu system select menu option: C: 8 and press ENTER.
•
Using the NEXT and PREVIOUS buttons, select the required sensor.
•
Press ENTER.
Note:
Pressing ENTER whilst in menu option C: 8 will reset the factory

Note:
It is important that the sensor selected via this menu option corresponds to the sensor
