Setting the Response Reading
1. Screw the regulator into the calibration gas cylinder.
2. Follow the directions in the controller operator’s manual for setting the response
(span) reading.
3. When the directions call for exposing the detector to gas, turn the regulator’s on/off
knob counterclockwise to open it. Gas will begin to flow.
4. Allow the gas to flow to the detector for 2 minutes.
5. Set the response reading according to the controller operator’s manual.
6. After setting the response reading, turn the regulator’s on/off knob clockwise to turn
it off.
Returning to Normal Operation
1. Unscrew the regulator from the cylinder and gently pull the calibration cup off of the
plug-in sensor.
NOTE: For convenience, leave the regulator and calibration cup connected by the
sample tubing.
2. Allow about 45 seconds for the gas reading to decrease below the alarm points and
then return the controller to normal operation.
NOTE : If you do not allow the gas reading to decrease below the alarm points, then
unwanted alarms may occur.
3. Verify that the controller display reading decreases and stabilizes at 0 ppm.
4. Store the components of the calibration kit in a safe and convenient place.
