... Gain Error The gain error of the FS6611 is defined as the difference between the measured output frequency (minus the offset) and the ideal output frequency measured with a gain Channel V1. The difference is expressed as a percentage of the ideal frequency. The ideal frequency is obtained from the FS6611 transfer function (see Transfer Function section) ...

... × Time Fig5 Signal Flow Diagram The low frequency output of the FS6611 is generated by accumulating this information. This low frequency inherently means a long accumulation time between output pulses. The output frequency is therefore proportional to the average real power. This average real power information can, in turn, be accumulated (e ...

... The FS6611 contains an on-chip power supply monitor. The Analog Supply (AV DD monitored by the FS6611. If the supply is less than 4V ± 5%, the FS6611 will be reset. This is useful to ensure correct device startup at power-up and power-down. The power supply monitor has built in hysteresis and filtering. This gives a high degree of immunity to false triggering due to noisy supplies ...

... Interfacing the FS6611 Controller for Energy Measurement The easiest way to interface the FS6611 to a micro-Controller is to use the CF high frequency output with the output frequency scaling set to 2048×F1, F2. This is done by setting SCF = 0 and (see Table Ⅳ). With full-scale AC signals on the analog inputs, the output frequency on CF will be approximately 5 ...

... Transfer Function 13.8.1 Frequency Outputs F1 and F2 The FS6611 calculates the product of two voltage signals (on Channel 1 and Channel 2) and then low pass filters this product to extract real power information. This real power information is then converted to a frequency. The frequency information is output on F1 and F2 in the form of active low pulses ...

... Note: When the high frequency mode is selected, (i.e., SCF = 1), the CF pulse width is fixed at 18µs. Therefore, t4 will always be 18µs, regardless of the output frequency on CF. FS6611 Frequency on F1 and F2 (Hz) (Ch1 and Ch2 Half Scale AC Inputs) 0.085 0.17 ...

... No Load Threshold The FS6611 also includes a “no load threshold” and “startup current” feature that will eliminate any creep effects in the meter. The FS6611 is designed to issue a minimum output frequency on all modes except when SCF = 0 and The no load detection threshold is disabled on this output mode to accommodate specialized application of the FS6611 ...
