A hysteresis of 50 ppm is applied to prevent the relay from switching back and forth when the
measured value is near the setpoint value. The relay is activated/deactivated when the
measured CO value passes the setpoint, plus/minus 50 ppm.

For example, consider a transmitter that has the relay setpoint set to
1000 ppm CO
1051 ppm. The relay remains activated until the measured value falls to 949 ppm.
