Default settings for measuring range module
The measuring range modules are preset to “B” (voltage; " 10 V) when the
module is supplied.
To use the following preset measuring methods and measuring ranges, you only
have to change the measuring range module to the corresponding setting.
Parameter assignment in STEP 7 is not necessary.
