Each channel of 66203/66204 has the ability to provide independent measurements; hence the meters are suitable for multi-point measurement
applications such as PV inverter testing. Instruments are designed for measuring DC input parameters as well as three phase AC readings on the output
side. The overall efficiency for the PV inverter can easily be obtained by built-in functions. In order to meet high voltage applications (up to 1200Vrms)

Average Mode and Integration Mode for Power Measurement
When using a traditional power meter, unstable measurements can occur if the UUT's power consumption are unstable or operating in non-linear modes
(i.e. a power supply's hiccup mode). In these cases the load levels maybe different at different measurement aperture windows (T1, T2, T3 and T4 below).
A simple averaging calculation can only provide a visual stable value but provides inaccurate power readings.
The 66203/66204 includes a Window Mode method which calculates all data within the user-defined time window (Tw). In this manner users can obtain
a real average value without data lose. An accumulated energy approach method (i.e. integration mode) for power measurements is also provided. This
integration mode calculates active power values by integrating energy from V and I in a user-defined time period (Ti). In this way, users can achieve
accurate readings with guaranteed transient-free variations. The 66203/66204 meters provide a 5mA minimum current range with crest factor 4, and
0.1mW measurement resolution for low power application (<10W), and less than 2% uncertainty even for No-Load mode power measurements. These
functions make 66200 an ideal choice for ENERGY STAR / IEC 62301 / ErP / SPEC Power measurement.

THD Measurement and User Define Level of Distortion
The 66203/66204 Power Meters can measure voltage and current Total Harmonic Distortion (THD) directly which can be displayed in percentage format.
For some requirements (ENERGY STAR), users need to verify the THD of AC supply voltage when supplying the UUT in the specified mode not to exceed
2%, up to and including the 13th harmonic (as specified in IEC 62301).
The 66203/66204 also provides a function to
define a user-specify level of distortion n, (n is
from 2 to 50) for measuring harmonic distortion.
The calculation formula is listed below. Thus, the

instrument can easily measure distortion values

as required by the ENERGY STAR requirements.
Inrush Current Measurement
The 66203/66204 Power Meters include built-in inrush current ( Is ) measurement functions. Users can even set a current level for triggering the starting
point of the measurement. Users also can use an external TTL signal to trigger inrush current measurements through the control I/O signal port located
at the rear side.

The delay parameter can help users to bypass the peak value B

time (T). The main purpose is to avoid measuring the inrush
current value that is generally caused by X-capacitor of a power
supply.

Low Pass Filter
The maximum measurement bandwidth of the 66203/66204 Power Meters is 50kHz. However, the high frequency component is not desirable in all
applications. For example, the input switching noise of some power supplies may influence the power measurement. In order to achieve a proper value,
a low pass filter is necessary to reject the switching component. Users can set the parameter filter ON in the system configuration setting. The bandwidth
will be reduced to 5kHz to reject high frequency content but still meets the 3kHz requirement of ENERGY STAR test.

The 66200 Power Meters provide graphical user interface software (Softpanels) which allow users to control and read measured parameters from a
computer via USB or GPIB interface. Users can easily observe measured voltage and current waveforms and monitor the changes in parameter readings
by using the chart function. Additional features include a recording function which can record selected parameters and write data to a file for further
analysis. The 66200 Softpanels supports IEC 61000-3-2* harmonic current limit test (pre-compliance) allowing users to examine whether the UUT has met
the harmonic current requirement. The Power Efficiency Softpanel* also integrates with Chroma's electronic loads and AC Sources to provide an easy
method of power efficiency testing and recording of data using the test report function which automatically generates a report at the completion of
testing.
