1. Safety instructions
The counter conforms to safety regulations for
electrical measuring instruments and control and
laboratory equipment as per DIN EN 61010, part
1. It is intended for operation in a dry environment,
suitable for the operation of electrical equipment
and systems.
Safe operation of the counter is guaranteed,
provided it is used correctly. However, there is
no guarantee of safety if the counter is used in
an improper or careless manner.
If it may be assumed for any reason that non-
hazardous operation will not be possible (e.g. visi-
ble damage), the counter should be switched off
immediately and secured against any unintended
use.
• Before using the counter for the first time,
confirm that the specifications printed on the
rear side of the housing are compatible with
the local mains voltage.
• Replace a faulty fuse only with one matching
the specifications stated at the rear of the
housing.
• Disconnect the counter from the mains be-
fore replacing a fuse.
• Never short the fuse or the fuse holder.
