Analog secondary values shows secondary CT currents and VT voltages. These are the
actual current and voltage values at the TRM inputs.
For analog values received from Merging Units, no analog secondary values are shown.
Main menu/Measurements/Analog secondary values
Displays up to 24 channels with secondary CT and VT data. RMS values are shown.

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.

mA input module MIM

Main menu/Measurements/Analog mean values/mA modules/MIM
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.

Signal matrix for mA inputs SMMI

Main menu/Measurements/Analog mean values/SMT mA modules/Instance
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.
