1001 MFA Multi-function display content_copy

The multi-function displays MFA in 1001 and MFA in 2001 universal electronic measuring instruments for the measurement and
monitoring of all important variable 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 operational and the direct indication of the functions of All These readings draw from multi-function displays.
integrated with on operating hours counter. using the MFA in 1001 as the base version, all are basic functions in four-wire low voltage network available data MFA 1001
