6.4 View analog mean values
6.4.1 Overview
Measurements from the Milliampere Input Module (MIM) are found in this part of
the measurements menu. Data from either the hard wired mA module or Signal
Matrix Tool mA modules are shown here.
6.4.1.1 mA input module MIM
Main menu/Measurements/Analog mean values/mA modules/MIM:x
Displays input data from the milli-ampere module which has six inputs. Each input
has a range of +/- 20 mA. The value displayed on the screen is however dependant
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
Main menu/Measurements/Analog mean values/SMT mA modules/Instance:x
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 Signal Matrix Tool.
6.5 View monitoring values
6.5.1 Service values CVMMXN
Main menu/Measurement/Monitoring/ServiceValues(MMXN)/CVMMXN:x
Displays up to three instances of CVMMXN with measured values for S, P, Q, PF,
U, I, ILead, ILag and F.
6.5.2 Current phasors CMMXU
Main menu/Measurement/Monitoring/CurrentPhasors(MMXU)/CMMXU:x
All three phase currents and their phase angles are displayed here.
