<Flow Rate Manual Adjustment "2-6" and Flow Rate Default Set
"2-5">
The flow rate of the detector is automatically adjusted to 0.5 L/min. Turning off the auto-adjustment function
enables the manual adjustment. (See 2-10 - SET-11)
The manual flow rate adjustment can be performed in the regular maintenance mode "2-6.FLOW".

Flow Rate Adjustment
As the output is increased or decreased by
pressing the ▲ or ▼ key, the flow rate
changes accordingly. Adjust the flow rate to
0.5 L/min, and then press the SET key.
(Press the MODE key to cancel this menu.)
Regardless of the flow rate auto-adjustment or manual-adjustment, when the reading on the flow rate
indicator is incorrect (due to aging degradation, improper flow rate default set, or other reasons), it must be
set to provide the right flow rate.
To set the Flow Rate Indicator, prepare and connect a flow meter (which indicates 0.5 L/min precisely), and
perform the default set with the flow meter while it is indicating 0.5 L/min in the regular maintenance mode
"2-5.DEF FLOW".

CAUTION
Perform the flow rate default set after verifying that the suction volume is 0.5 L/min by using a flow meter.
