If a sampling line and/or moisturizing bottle are to be used with the instrument, they must be connected to the instrument while the calibration is checked. 1. Attach the flow control to the calibration gas tank.

4.

Open the regulator valve.

5. Set the MODE switch to the ON position and the RANGE switch to the range being checked. 6. Allow the instrument to reach a stable indication. Adjust the SPAN control, if necessary, to obtain the correct indication for the calibration gas used. 7. Remove the hose from the regulator and instrument.

2. Connect the hose to the flow control. 8. Close the regulator valve. 3. Connect the hose fitting to the instrument inlet or to the instrument sampling line, if one is to be used.
