1. Safety Instructions
The electric field meter complies with the safety
requirements of DIN EN 61010, part 1, relating to
electrical measurement, control and regulation
applications and for laboratory instruments, and its
design complies with protection class I. It is designed
for operation in dry environments suitable for
working electricity.
Safety is guaranteed if the instrument is used as
stipulated. However, safety cannot be guaranteed in
cases of incorrect or careless operation.
If there is reason to suspect that safe operation is no
longer assured, the instrument must be taken out of
use immediately.
In schools and other educational establishments, the
instrument may only be used under the supervision of
a responsible person.
• Before using the instrument for the first time,
check that the local mains voltage corresponds
with that printed on the back of the housing.
• Before using the instrument, examine the housing
and the mains cable. If there is visible damage or
if the instrument does not function properly, take
it out of service and secure it to prevent
unauthorised use.
• The instrument may only be plugged in at a mains
socket with an earth connection.
• The capacitor plate and the voltage measurement
plate must only be put in place when the
instrument is switched off.
