When removing or replacing a lid, hold the lid firmly and turn the container to 

avoid twisting the hose.

The hoses are now filled by flushing (see 6.4 / 6.4.1). Make sure there are no air 

bubbles in the dosing hose.

If a pump has been loaded with embedding material but you do not want to dose 

immediately, seal the hose end with the rubber plug provided.

Finally

, insert the power plug into the socket, making sure that the mains and the 

unit operate on the same voltage.

The scales should be level, clean and free of any unwanted loads.

When you turn on the power, autotest characters (

C1 

to

 C6

) appear on the display, 

followed by the character or number of the program, then 

0

 to indicate the scales 

have been tared.

Now you can

 weigh, dose, rinse 

or 

program.
