Hydrogen Compensated Calibration
WhereaCOhydrogencompensatedgassensoristtedthesensormust
also be calibrated using hydrogen.
Select hydrogen from the menu and continue as for normal calibration.
10.5 Performing an Upscale Calibration
1) Make sure that you have a list of the calibration gas concentrations -
you will need to enter these values during calibration.
2) The Lancom 4 must be calibrated in a well ventilated environment.
The exhaust gases must be vented to a safe area.
Check that the exhaust extraction is functioning correctly.
3) Before you begin calibrating, perform a zero calibration. From the Main
Menu, select Calibration > Recalibrate.
4) When zero calibration is complete, connect the calibration gas supply to
theuegasportontheanalyser.
5) Set the pressure regulator on the calibration gas cylinders to 0.7 bar
(10 psi) and turn on the gas supply. Adjust the regulator valve so that
theowmeter(4)showsaowofapproximately2litresperminute.
6) From the Calibration menu select Manual Calibration.
7) Use the up arrow key to display the password (0010), then press enter.
8) Select the Gases option, then select the gas sensor you are going to
calibrate and press enter. The sample pump will start.
9) Connect the calibration gas and use the cursor keys to select the
calibrationgasconcentration.Thereshouldbeasmallamountofow
from the bypass outlet (5); if not, adjust the regulator valve so that
thereispositiveow.Pressenterwhenreadytocalibrate.
