UMG 96RM-P/-CBM
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-P/-CBM.
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
Backlight
The LCD backlight allows the display to be read easily
even in poor light. The brightness can be controlled by
the user in stages from 0 to 9.
The UMG 96RM has two different types of backlight:
- the operation backlight
- the standby backlight
