UMG 96RM
Rotation field direction
The rotation field direction of the voltages and the
frequency of phase L1 are shown on the display.
The rotation field direction indicates the phase sequence
in three-phase systems. Usually there is a "clockwise
spinning rotation field".
The phase sequence at the voltage measurement inputs
is checked and displayed in the UMG 96RM. A movement
of the character string in the clockwise direction means
a "right rotation" and a counter-clockwise movement
indicates a "left rotation".
The rotation field direction is determined only if
the measurement and operating voltage inputs are fully
connected. If one phase is missing or two of the same
phases are connected, the rotation field direction will not
be determined and the character string does not appear
on the display.

LCD contrast (addr. 035)
The preferred direction of viewing for the LCD is from
"below". The user can adjust the LCD contrast of the
LCD screen. It is possible to set the contrast in the range
from 0 to 9 in steps of 1.
0 = characters are very light
9 = characters are very dark
Factory default setting: 5
Backlighting (addr. 036)
The backlighting makes the LCD display easy to see
in poor visibility conditions. The user can adjust the
backlight brightness in a range from 0 to 9 in steps of 1.
0 = minimum backlight brightness
9 = maximum backlight brightness
Factory default setting: 6
