Setting up the measuring range using the measuring range module

Measuring range module

A measuring range module is installed on the left-hand side of the analog I/O module. Use
this measuring module to define the type of measurement at the analog inputs, i.e. voltage or
current measurement.
Settings
The measuring range module features the optional "A", "C" and "D" settings. Setting "D" is
the factory default.
The following table shows the assignment of the measuring range settings for the module's
analog input circuitry.
Set up the measuring range in HW Config. You can choose between different current or
voltage ranges; refer to chapter Configuring and parameterizing (Page 43). HW Config also
displays the required setting for the measuring range module.
