The higher that the flow rate of meter “A” is set, the sooner its indication will be stable. Also, since
the instrument has air in the internal piping, regulator, or sampling tube, we recommend adjusting
the flow monitor “A” so that it is more than 0.8 L/min every first turn when measuring.
SECTION 5. OTHER OPERATION
5-1. Incase of checking zero or suspending measuring, turn the change over cock (measuring
gas/air) sideways.
5-2. It is enough for further measuring to set flow meter “A” 0.5 L/min
*The unit can also accept the flow rate being set still 0.8 L/min.
Quit Measuring and Turn Off Instrument
SECTION 1. APPLY FRESH AIR
1-1. It is necessary for the unit to apply fresh air before turning off. Turn the change over the cock
(measuring gas/air) sideways to apply fresh air.
1-2. Press the power button until the LCD display goes out. The buzzer will beep three times while
pressing the power button.
