Using Clamp-On Ferrites

1.4CE Comments

1.4.1EMC Directive

Hart Scientific’s equipment has been tested to meet the European Electromagnetic Compatibility Directive (EMC Directive, 2004/108/EC ). The Declaration of Conformity for your instrument lists the specific stan- dards to which the unit was tested.

The instrument was designed specifically as a test and measuring device. Compliance to the EMC direc- tive is through EN 61326-1:2006 Electrical equipment for measurement, control and laboratory use – EMC requirements

As noted in the EN 61326-1, the instrument can have varying configurations. The instrument was tested in a typical configuration with shielded RS-232 cables.

1.4.2Immunity Testing

The instrument was tested to the requirements for laboratory locations.

1.5Using Clamp-On Ferrites

Clamp-on ferrites are provided for use in improving the instrument’s electromagnetic (EM) immunity in envi- ronments of excessive EM interference, like areas of heavy industrial equipment. We recommend placing the ferrites on the cables of probes attached to the instrument.

To attach a ferrite to a probe cable, make a loop in the cable near the connector and clamp the ferrite around half of the loop as shown in the diagram. The ferrite can be easily detached and moved to a new probe when needed. (See Figure 1 on next page.)
