MEASUREMENT PREPARATION 

(1) Connecting the adapter (tube) to the main unit 

Remove the air plug located on either side of the main 
unit. Connect the tube of the adapter to the main unit.     
* The air plugs and the adapter tube are connected 

by a coupling having a lock function. When 
removing the air plug or tube, while pushing on 
the release ring located on the connector opening 
(1), pull it out (3) after pushing the air plug or 
tube lightly (2). 

 

* When connecting, confirm that the air plug or adapter 

tube is pushed in the connector hole firmly.

 

 

 

 

 

 

 

(2) Connecting the attachment (pipette side) 

The accessory attachments provided have three 
different pipettes tip sizes. Select the attachment in 
order that the tip and pipette size match up, then 
connect the attachment to the adapter. 

 

 

 

 

 

 

 

 

 

When the pipette does not match up with the attachment provided, replace the 
tip of the attachment with a tip that matches the pipette.
