Figure 4-53 Example of Inrush Current Measurement
1. The fastest sampling rate of the 66203/66204 power meter is 4
μ
s,
so when the maximum inrush current is occurred within 4
μ
s, the
best measurement may be missed. The inrush current sampling
rate varies with the voltage frequency detected. The sampling rate
of measured 50Hz signal is about 5
μ
s. The sampling rate of
measured 60Hz is about 4
μ
s.
2. The 66203/66204 Digital Power Meter has 3 types of parameters
that require TRIG/ENTER for triggering, they are E (Energy), Is
(Inrush Current) and GO/NG. The priority is E > Is > GO/NG.
3. When the inrush current measurement is triggered, every channel of
the 66203/66204 power meter will start measurement at the same
time. The inrush current value can be checked by pressing the
channel key for switch.
ENERG
Figure 4-54 ENERGY Setup Screen
The 66203/66204 Digital Power Meter is able to measure the UUT’s energy within a period of
time. The energy units for selection are Joule and WHr. The calculation of energy is the
integration of active power to time. Changing the voltage or current range within the
