With this configuration, the relay activates when measurement falls below the value
entered in the Activate below field (100 ppm in this example). When the measurement

the combined value of the activation limit and hysteresis buer (120 ppm in this example).
For further examples on the eect of hysteresis, see Figure 20 (page 36).
