10.6.3 Operating the Zero Gas Flow Setting Valve
Operate the zero gas ow setting valve during zero-point calibration in the following procedures:
(1) When the display shown in Figure 10.19 appears during calibration, open the zero gas
ow setting valve of the ow setting unit and adjust the ow rate to 600 ± 60 ml/ min. To
rotate the valve shaft, if the valve has a lock nut loosen the lock nut and slowly turn it
counterclockwise. To check the ow rate, monitor the calibration gas owmeter.
If the sample gas pressure is extremely high, adjust the sample gas pressure to obtain
pressures (listed in Table 10.6) ± 10%.
Table 10.6
Sample gas pressure (kPa) 50 100 150 200 250
Flow rate (ml/min) 500 430 380 350 320

Open zero gas valve.
Set flow zero gas to
600ml/min.

(2) Adjust the ow rate and select “Valve opened” from the Manual calibration display.
Check the Trend graph display to see that the measured value is stabilized. Then press the
[Enter] key. The Manual calibration display shown in Figure 10.20 appears.

(3) Close the zero gas ow setting valve to stop the zero gas ow. If the valve has a lock nut,
be sure to tighten the lock nut to prevent the any leakage of the zero gas into the sensor
because the valve may become loose during measurement.
10.6.4 Operation After Calibration
No special operation of the instrument is needed after calibration. However, it is recommended
that the pressure reducing valve for the zero gas cylinders be closed because calibration is not
required so often.
