Adapting Analog Output (Scale) (Only For - AEG Thyro-A Operating Instructions Manual

4.3.6 Adapting analog output (scale) (only for ...H RL1 and ...H RLP1)
The scale of the analog output is adapted with potentiometer R204
SCALE OUTPUT, if, for example, the scale of the display does not cor-
respond to the nominal data (see page 41, Analog output).
