10. 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 can not 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.
