10.6 Cleaning
• Do not use solvents to clean the EFA-200/-300 casing or probes or the
Power Supply Unit. We recommend the use of lukewarm water to which
a little liquid detergent has been added.
• Only use a slightly dampened cloth for cleaning. Water must nor be
allowed to get inside the instrument.
• To prevent streaks and spots when drying, wipe off the still damp
surfaces of the instrument with a dry cloth.
