Risk of infection from sample residue!

The initiation needle is immersed into the sample during measurements. Contact with the initiation needle 

increases the risk of infection.

• 

Wear lab gloves during any kind of work.

DANGER!

Risk of death due to electrical current!

1.  Power down device using on/off switch on rear side and disconnect power
