Be sure to perform zero/span calibration of each component after the warm-up operation is completed.
3.2.1 Zero calibration time and span concentration value setting
(See "4.1.2" for setting method.)
(1) Zero calibration time
1) Select <Menu Mode> → <2. Setting about Calibration> → <1. About Zero Calibration>, and select
zero gas flow time.
(2) Span calibration concentration value setting
1) Select <Menu Mode> → <2. Setting about Calibration> → <2. Span Calibration Value>, and
change calibration gas concentration value for each component range.
3.2.2 Switching ranges (See "4.1.4" for setting method.)
(1) Select <Menu Mode> → <4. Changeover of Range>, and enter span calibration concentration for
each component range.
3.2.3 Zero/span calibration (See "4.1.1" for calibration method.)
(1) Select <Menu Mode> → <Zero/Span Calibration>, and perform zero/span calibration.
3.2.4 Adjusting flow rate
(1) A diaphragm is installed within the instrument to make sure that pressurizing the cylinder gas to
0.03MPa from the calibration gas inlet (CAL) allows the flow checker ball to come at the center of
the yellow zone (approximately 0.5 L/min). Finely adjust the pressure of the cylinder gas, while
checking the position of the flow checker ball.
(2) The same kind of diaphragm is also installed at the sample gas inlet. Check in the measurement
state (while the pump is operated by setting the
the upper limit of the yellow zone (approximately 0.7 L/min).
Caution on operation
• The flow channel of the sample gas (during measurement) within the instrument is different from
that of the calibration gas (zero, span). Make an adjustment using the needle valve as required.
