(4) Calibration command
Give a calibration command after fi nishing the procedure in 3.2.5 Parameter Setting. The
procedure is as follows:
(a) Auto calibration
(1) Change the user level.
(2) Press
the (OPR) in the navigation bar on the analyzer operation screen.
(3) Set the operation mode to Process.
(4) Display the EtherLCD screen and display the Calibration Set screen.
(5) Confi rm the set values of the Cal/Val Setup screen.
IMPORTANT
If the operation mode is Run at the time set in Auto start time, calibration starts after the
measurement of the stream. After the calibration, the mode returns to Run and the measurement
restarts. (When the operation mode is Stop or Pause, calibration is not conducted.)
(b) Semi-auto calibration
(1) Connect a cylinder or a pump to the standard sample stream in reference to Connecting a
Standard Gas Cylinder or Standard Liquid Pump.
(2) Change the user level.
(3) Press
the (OPR) in the navigation bar on the analyzer operation screen.
(4) Open the GCM tab, and set the operation mode to Process.
(5) Select Semi-auto in the Cal (Val) method screen (see Figure 3.25) and press OK.
(6) Select a desired calibration number in the Cal (Val) method screen and press OK.
(7) After the calibration stream and the validation stream are measured according to the
settings, the calibration fi nishes.
