About Electrical Zero Offset
If you want to shift a small, calibrated sensor range away from the sensor’s calibrated electrical zero, you can
offset the sensor’s electrical output in the conditioner.
A traditional offset shifts the feedback signal and an electrical zero offset shifts the conditioner signal.
An electrical zero offset cannot be applied to a conditioner used in an active control mode with hydraulic
pressure applied.
