When the value of the instantaneous flow rate
stabilizes, press the "START/STOP Button" to test
the air leakage.
●
Test result
●
[Good (no air leakage)]
Criterion value: Instantaneous flow rate
3mL/min or less
The value of instantaneous flow rate blinks three
times.
[Error (air leakage)]
Criterion value: Instantaneous flow rate greater
than 3mL/min
"L.Err" is displayed after blinking.
At the same time, the status lamp flashes in red.
[Normal (no air leakage)]
[Error (air leakage)]

If not, press and hold the "POWER Button" to exit
the calibration mode. (The power is turned off.)

Note
If the instantaneous flow rate does not fall below 3mL/min during the leak check ("L.Err" is
displayed), there is a possibility of air leakage. Please check the items described below.
i. Activate the calibration mode, perform the zero point adjustment referring to "7.5 Zero Point
Adjustment", and then perform the leak check again.
ii. Remove the suction inlet and check that there is no dust, cracks, etc. on the sealing O-ring,
and check that there is no dust or scratches on the sealing surface of the inlet referring to
"8.1 Replacing the Dust Filter and O-ring". Remove any dust, etc., and check again for air
leakage. If there is a scratch on the sealing surface, it must be repaired.
iii. If the instantaneous flow rate does not fall below 3mL/min even after confirming i and ii,
there is air leakage inside the pump and it must be repaired. Please refer to
「
11.1 Repair
」
for repair request.
During the leak check (
⑤
above), if no operation is performed for 10 minutes, " " is
displayed, and the display returns to the state of the item selection in the calibration mode.
