They are electrically insulated from each other and from all other circuits (fl oating).All the full-scale output values can be reduced subsequently using the programming software, but a supplementary error hardware full-scale settings for the analog outputs may also be changed subsequently. Conversion of a current to a voltage output or vice versa is also possible.

8 This necessitates changing resistors on the output board. The full-scale values of the current and voltage outputs are set by barying the effective value of two parallel resistors (better resolution). The values of the resistors are selected to achieve the minimum absolute error. Calibration with the programming software is always necessary following conver-sion of the outputs.
