This option allows users to calibrate the sensor's span.
Note: When calibrating a duct mounted unit,it is best to remove the unit
from its base to ensure proper calibration.
• Before starting the calibration (using the programming menus),
connect the regulator to the gas cylinder.
• Adjust the flow rate to 0.1 L/min.(for the 2000 ppm range)
• Connect the tubing from the regulator to the sensor, as shown in
the image at left.
