2001 MFA Multi-function display content_copy

The multi-function displays MFA 1001 and MFA 2001 universal electronic measuring instruments for the measurement and
monitoring of all important variables in the three-phase mains.
The LC display with backlight (MFA 2001) provides a safe and glare-free reading even from a distance.
A user-friendly operation and the direct indication of the functions of all measured values ​​characterize this multi-function displays from.
using integrated an hour meter. using the MFA in 2001 and the advanced features to the basic version next are a phase failure relay function further parameters and additions to the network analysis. Various data interfaces are optionally available measurement data MFA 2001
