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, grounded

probe and RS-232 cables. Emissions may, in non-typical applications, exceed

the levels required by the standard. It is not practical to test all configurations,

as the manufacturer has no control over the probes the user may connect to the

instrument.

11.2.1.1 Immunity Testing

The instrument was tested to the requirements for industrial locations. This al

lows the instrument to be used in all types of locations from the laboratory to

the factory floor. Criterion B was used for Radiated RF (IEC 61000-4-3) and

Conducted RF (IEC 61000-4-6). Therefore, the operation of the instrument

may be affected by excessive electromagnetic interference and the instrument

may not perform within the normal specification limits in such an environment.

Criterion C was used for Electrostatic Discharge (ESD, IEC 61000-4-2) and

Electric Fast Transit (EFT, Burst, IEC 61000-4-4). If the instrument is sub-

jected to EFT conditions at 2kV, the instrument may require the user to cycle

the power to return to normal operation.

11.2.1.2 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.

11.2.2 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.
