of Conformity for your instrument lists the specific standards to which the unit
was tested.
The instrument was designed specifically as a test and measuring device. Com
-
pliance to the EMC directive is through IEC 61326-1 Electrical equipment for
measurement, control and laboratory use – EMC requirements (1998).
As noted in the IEC 61326-1, the instrument can have varying configurations.
The instrument was tested in a typical configuration with shielded and
grounded probe and RS232 cables. Emissions may, in non-typical applications,
exceed the levels required by the standard. It is not practical to test all configu

nect to the instrument.
13.2.1.1 Immunity Testing
The instrument was tested to the immunity requirements of the IEC 61326-1
according to Table 1 – Minimum immunity test requirements. Criterion B was
used for Conducted RF (IEC 61000-4-6) and Electric Fast Transit (EFT, Burst,
IEC 61000-4-4). Therefore, the operation of the instrument may be affected by
excessive electromagnetic interference and may not perform within the normal
specification limits under these conditions.
13.2.1.2 Emission Testing
The instrument fulfills the limit requirements for Class A equipment but does
not fulfill the limit requirements for Class B equipment. The instrument was
not designed to be used in domestic establishments.
13.2.2 Low Voltage Directive (Safety)
In order to comply with the European Low Voltage Directive (73/23/EEC),
Hart Scientific equipment has been designed to meet the IEC 1010-1 (EN
61010-1) and the IEC 1010-2-010 (EN 61010-2-010) standards.
