6.2.1
Overview
The analog primary values are analog quantities measured on the primary side of the
TRM and reflect the actual current or voltage on the primary side of the VTs and CTs.
The ratio is adjusted under settings and also depends on the rating of the TRM. 24
primary values and phase angles are displayed in this view.
Measurements/Analog Primary Values
Displays the quantities measured by the transformer module (TRM). For each channel
used the amplitude of the voltage or current and its phase angle is shown. The status
of the module is always shown and channels not in use are indicated with the
abbreviation NC. Data from up to two TRMs and four LDCMs can be viewed. All
currents and voltages are given in RMS values.

View analog secondary values
6.3.1
Overview
Analog secondary values shows secondary CT currents and VT voltages. These are
the actual current and voltage values at the TRM inputs.
Measurements/Analog Secondary Values
Displays up to 24 channels with secondary CT and VT data. RMS values are shown.

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 the Signal
Matrix Tool mA modules are shown here.
6.4.1.1
mA input module (MIM)
Measurements/Analog Mean Values/mA modules/Instance No./AI
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
