Once the correct code is reached, pressing the On/Off/Mode button will
navigate to the next configuration screen which is the Combustible Gas
Sensor Operating Mode screen. If the On/Off/Mode button is pressed
while the wrong code is displayed, the instrument will leave the
configuration screen and return to the Gas Monitoring screen.
IMPORTANT: To reset the code to the default code of 000, enter 412
then press both On/Off/Mode and Enter buttons simultaneously.
IMPORTANT: Any change made while in the configuration mode will take
affect immediately upon exiting the configuration mode.
Combustible Gas Operating Mode Screen
The Combustible Gas Operating Mode
screen displays the up and down arrow
icons, the GAS icon, and either the LEL
(low explosive limit) or CH
4
(methane) text.
From this screen you set the combustible gas mode by toggling between
the two options – lower explosive limit (LEL) or methane (CH
4
). Use the
Enter button to toggle between these values. After the desired
combustible gas operating mode selected, press the On/Off/Mode button
to display the zero initiate screen. If the mode is changed, the sensor will
be automatically put into the calibration fail mode to ensure correct
calibration.
Be aware that if the combustible gas mode is changed and the user exits
this screen, the last shown value is saved and the sensor will enter a
calibration fail state (the calibration fail alarm will sound). A calibration will
be required to clear the alarm state.
