The multimess D9-PQ fulfills the requirements laid down in IEC 61000-4-30 (2008) for class A measuring devices to 100%.

multimess D9-PQ also features a high-speed fault recorder with a recording rate of 40.96kHz/10.24kHz and a 10ms RMS recorder. Thus, it allows for a detailed assessment of network interferences.

The unit is especially suitable for mon-itoring, recording and evaluating ref-erence qualities or quality agreements between the energy supplier and the customer and make them available for evaluation and storage.

Advanced voltage quality measuring devices work in accordance with the IEC 61000-4-30 (2008) standard. This standard defines the measuring meth-ods to provide users with a good basis for comparison.Devices from different manufacturers that comply with this standard have to deliver identical measuring results.

The standard distinguishes two measuring device classes:

class A measuring devices are mostly used for contract-relevant measurements in customer-sup-plier relationships.

class S measuring devices can be used to determine statistic quality values.
