(6) Mount the Rc1/4 joint to the calibration gas cell, and connect one side to the standard gas cylinder (N
2
).
(7) When the pipe is connected as shown below, allow the gas to flow.
(8) Flow of sampling gas should be 1.5L/min.
(9) When you mount thermometer and pressure gauge as shown below, connect output of 4 to 20mA DC to
analog input terminal of the control unit, referring to “3.2 Input/output terminal of control unit”. Also,
set analog input, referring to “6.7.1 Setting of 4 to 20mA DC Input (in case of gas temperature)”.

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 1.5L/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 if the indication value is stable.
(9) Warm up for about 90 minutes if the analyzer was shutdown for a long time.
(10) Point the to “ZeroCal.Start”, and press the
ENT
key to start the zero calibration.
