Instron servohydraulic testing systems have a zero suppression feature that shifts the absolute zero of the command waveform to an offset or "apparent" zero It is used to improve resolution when using a waveform that is small in relation to the full scale range in use It is also used when the actuator is offset from its normal or absolute zero to accommodate large grips or long specimens
the span of an indicator or chart recorder may be offset from zero (zero suppressed) such that neither limit of the span will be zero For example, a temperature recorder which records a 100 degree span from 400 degrees to 500 degrees is said to have 400 degrees zero suppression
a process used to increase system sensitivity of sensors with a large output offset By suppressing the zero, higher amplification may be applied The bridge circuit is an example
