5.5.10 Analog input scaling curves
Sometimes when measuring with RTD inputs, milliampere inputs and digital inputs the measurement
might be inaccurate because the signal coming from the source is inaccurate. One common example
of this is tap changer location indication signal not changing linearly from step to step. If the output
difference between the steps are not equal to each other, measuring the incoming signal accurately is
not enough. "Analog input scaling curves" menu can be used to take these inaccuracies into account.
Analog input scaling curve settings can be found at
Measurement
→
AI(mA, DI volt) scaling menu.
Currently following measurements can be scaled with analog input scaling curves:
• RTD inputs and mA inputs in "RTD & mA input" option cards
• mA inputs in "mA output & mA input" option cards
• Digital input voltages
