Figure 4-35 Process for Setting Shunt
When switching Shunt, it will take around 300ms to dodge the transient
of the switch. If the test range is concentrated in 20Arms/5Arms/2Arms/
0.5Arms (High shunt range) or 0.2Arms/0.05Arms/0.02Arms/0.005Arms
(Low shunt range), a proper shunt can be select for measurement to
shorten the testing time.

Figure 4-36 WINDOW Measurement Setup Screen
The 66203/66204 Digital Power Meter provides two average methods to calculate the
measured values. They are Windo (window) and Avg (average). The major differences of
them are sampling and calculation as described below.
■ Windo
When the UUT’s voltage or current signals are unstable, it can use Moving Window
Method to get a stable measured value. The longer the window time is set, the more
stable the measured value is.
