The multimess D9-PQ has been developed for measurements perfromed within
public grids as well as for recording PQ data within an industrial environment
up to 690V (L-L) measurement voltage.
No moving parts (fans, hard drives etc.)
CAT IV
Extensive storage capability (can be extended up to 32 GB by the user, permit-
ting several years recording without connection to database)
Optional “IEC61000-4-7 - 2kHz to 9kHz” (B1)
Frequency measurement of voltage and current according IEC 61000-4-7
from 2 kHz to 9 kHz.
Standard IEC61000-4-7 describes the measuring of harmonics and interhar-
monics in power supply grids and connected devices
