(6) Mount the Rc1/4 joint to the calibration gas cell, and connect one side to the standard gas cylinder (N
(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)".
