3.5 Electromagnetic compatibility
This instrument meets the requirements of EN 50081-1 and
is within Limit Class B of EN 55022 (identical with CISPR
22:1985 and DIN VDE 0878 Part 3).
The instrument has been tested to ensure that the EMI/RFI
emission requirements are also met when it is used as part
of a system.
For this condition to be met, the system must be correctly
assembled and the appropriate connecting cables used.
Adequate screening must be provided.
If the device under test connected to this instrument can
itself emit electromagnetic interference, users must ensure
that emissions remain within permitted limits. Suitable
measures should be taken to ensure that screening is
contiguous.
When used in a balanced system, the device under test itself
must be adequately balanced.
Electromagnetic emissions can be further reduced by
operating the instrument from dry or rechargeable batteries,
particularly if high signal levels are involved.
3.6 Cleaning the instrument
If the instrument has become dirty through use, it can be
cleaned using a soft cloth moistened with a mild solution of
detergent. Make sure that the cleaning solution does not get
inside the instrument. Parts which have become very dirty
may also be cleaned carefully using alcohol.
