MAINTENANCE AND NOTES

(1) Removing the attachment
After measurement, remove the pipette and accessory by the following procedure.
When storing the main unit, allow of the Leak Tester to equalize to atmospheric
pressure.
1) Remove the pipette from the attachment.
2) Remove the attachment from the adapter.
At this time, if the attachment is still connected
to a pipette, the inside pressure of the Leak
Tester will not return to atmospheric pressure.
(2) Storing
When storing the leak tester, avoid dust from invading the main unit and connector
tube (adapter, attachment). Close the cover of the AC adapter jack.
1) Adapter
Dust cannot enter the main unit when connected
to the accessory adapter. The connector has the
airlock function. Therefore, the Leak Tester is
protected from invading dust.
But if the connector part of the adapter becomes
dirty, dust may invade at the next measuring.
2) If the attachment is connected to the adapter,
dust may invade through the attachment. When
storing, remove the attachment.
