on the settings for the Milli-ampere Module. In the menu for settings, the range and
a transformation factor can be adjusted to suit the application. This means that an
input 3 mA may be displayed as temperature of 45 degrees. The output values shown
are without units.
6.4.1.2
Signal matrix for mA inputs (SMMI)
Measurements/Mean Analog Values/SMT mA modules/Instance No./AI
Displays the input signals coming into the Milli-ampere Module. Each module has
six physical inputs with an input tolerance of +/- 20mA. The value displayed depends
on the settings applied to this board which may for example cause an input of 3mA
to show a value 30. The SMT mA modules are the virtual representation of MIMs in
the Signal Matrix Tool.

Service values
Measurement/Monitoring/ServiceValues(MMXU)/SVR
Displays up to three instances of SVR with measured values for S, P, Q, PF, U, I,
ILead, ILag and F.
6.5.2
Current phasors
Measurement/Monitoring/Current Phasors/CPxx
All three phase currents and their phase angles are displayed here. As many as 10 sets
of current data can be shown.
6.5.3
Voltage phasors
Measurements/Monitoring/Voltage phasors/VPxx
Phase to phase voltages and phase angles are displayed here. Up to three sets of
voltage data can be displayed.
6.5.4
Current sequence component
Measurements/Monitoring/Current Sequence Components (MSQI)
The current sequence component under monitoring displays the positive (I1),
negative (I2) and zero sequence (I0) current values for a three phase line, both
magnitude and phase angle for each component are displayed. These indicate how
well balanced a system is. In an ideal balanced system the zero sequence current
