Instruction sheet

02/08 ALF
The apparatus conforms to the safety requirements
for electrical equipment for measurement, control
and laboratory use of DIN EN 61010 part 1 and is
classified as belonging to protection class I. It is in-
tended for operation in dry rooms that are suitable
for electrical equipment or installations.
Safe operation of the apparatus is guaranteed with
correct handling. However, safety is not guaranteed if
the apparatus is handled improperly or carelessly. If it
is to be expected that safe operation is impossible
(e.g., in case of visible damage), the apparatus is to be
rendered inoperative immediately and to be safe-
guarded from unintentional use.
1. Safety instructions
In schools and training institutions, operation of the
apparatus is to be responsibly supervised by trained
personnel.
•
Before first use, check if the apparatus is designed
