6.1.2 Zero calibration
(1) If the power is OFF, turn it ON.
(2) Check if the flow of N
2
gas is approximately 1.5 to 2.0 L/min.
(3) Display the “Zero Calibration” screen.
(4) Point the to “Component”, and press the
key.
(5) Press the
key or the
key to select the measured gas component to be zero-calibrated.
When there is only one component, it is not necessary to select. Note that, gas component and flowing
gas are not equivalent.
(6) Point the to “Cell Length”, and press the
key.
(7) Enter the length of calibration gas cell. Standard cell length is 1000mm. (When the range is low con-
centration, the length of calibration gas cell can be either 500mm or 200mm.)
(8) See the “Meas.” and make sure the indication value is stable.
(9) Point the to “ZeroCal.Start”, and press the
key to start the zero calibration.
(10) “ZeroCal.Start” blinks for about 30 seconds.
(11) When the calibration is completed, the cursor moves to “Cal.Finish”, and the current date is displayed
