A&D Weighing AD-1690 - Manual (Page 12)

10
When the pressure, with any leakage does not reach －20kPa or when the quantity
of pressure change is over the setting value after reaching －20kPa, the Leak Tester
judges that there is a leak and displays “fa1l” (abnormality).
When pressing the START key, while in the middle of a measurement, the
measurement stops and “5top” is displayed.
When pressing the START key again, the Leak Tester judges the measurement
result (
“pa55”/”fa1l”) after operating the pump again.
When finishing the measurement, remove the
pipette from the tip of the attachment.
If the pipette has the ejector (for releasing the
tip), remove the pipette by operating the ejector.
When measuring another pipette, press the
START key again after connecting the pipette
to be measured (return to “(2) Starting
measurement”). The leak tester starts the
measurement. At this time, the display is the
measurement result.
* When kept in a state of having the air evacuated, in the case of not removing the
pipette, the pump does not operate again.
(4) Measurement end
When finishing the pipette measurement, Press the ON:OFF key to turn the power
supply off. (After “off” is displayed, the power supply turns off.) Then, disconnect the
AC adapter from the main unit.
For storing, refer to “10. MAINTENANCE AND NOTES”.
