Measurement parameters

The 66205 power meter is capable of providing the following reliable and accurate measurement parameters:Vrms, Vpeak +, Vpeak-, V_harmonic, V_THD, CFV (Crest Factor Voltage), Irms, Ipeak +, Ipeak-, I_harmonic, I_THD, Is (Inrush Current), CFI (Crest Factor Current), W, VA, VAR, PF, Freq_V, Freq_I, Wh, Ah, º (phase step).

Parameter measurement method ： uninterrupted continuous moving window averages the measurements of voltage and current parameters in a time frame. Note: the time frame setting is equivalent to the data update rate x AVG number setting.

Linear filter function

The line filter is a digital low-pass filter with a high attenuation ratio of ≥70dB. When the line filter is enabled, the measured value will not contain high-frequency content, such as high-frequency noise in the switching converter. There are three sets of line filters with cutoff frequencies available on the 66205: OFF, 500 Hz and 5.5 kHz. The line filter with a cutoff frequency of 5.5 kHz complies with IEC 61000-3-2 international standards, and it is recommended to enable this filter when measuring harmonics.

Harmonic measurement function (IEC mode)

The 66205 is designed to meet the harmonic measurement requirements of IEC 61000-4-7. In IEC harmonic measurement mode, it allows the user to obtain a THD measurement result consistent with that of high-end power analyzers complying with IEC 61000-4-7.

Inrush current measurement function

The 66205 power meter has a built-in inrush current (Is) measurement function. Users can set the current level to trigger the measurement starting point. Users can also use an external TTL signal to trigger the inrush current measurement through the control I/O signal port on the back of the unit. The delay parameter can help users bypass the B peak value after the A trigger point. The T parameter allows users to set a preset time period to measure the peak value at a preset time (T).
