Switching Point
The U2000 Series USB power sensors have two measurement paths: a low
power path and a high power path as shown in Table 3- 3.
Table 3-3 Switching point
The power sensor automatically selects the proper power level path. To
avoid unnecessary switching when the power level is close to the
switching point, Switching Point Hysteresis is added.
