3 Cleaning Information
96
Cleaning the housing and the mainframe When cleaning either the
mainframe or the housing of your instrument, only use a dry and very soft
cotton tissue on the surfaces and the numeric pad.
Never open the instruments as they can be damaged. Opening the
instruments puts you in danger of receiving an electrical shock from your
device, and renders your warranty void.
