number in the Samples to Average field. The user should stop continuous conversion before leaving this
window. The Continuous Conversion button should not be used with BAUD rates less than 1200 Hz in
UART mode. Using lower BAUD rates (including the default 600 baud) will result in overflowing the
communication buffer and cause other window errors and/or communication failure.
Data logging can be enabled using the DATALOG On/Off check box and Filename field.
2.7.3 Standby Mode Button
When this button is pressed, the CS5480 will enter a standby power saving mode. To return to normal
mode, press the Power Up button. The user should power up the device before leaving this window.
2.7.4 Power Up Button
The Power Up button is used to send the wake-up command to the CS5480. The CS5480 will return to
normal operating mode.
2.7.5 Line Frequency Result
When the AFC bit in the Config2 register is set, the Epsilon register will be calculated automatically by the
CS5480 and the Line Frequency fields will be updated automatically in continuous conversion mode. If
the AFC bit in the Config2 register is not set and the line frequency is other than the default value (50 Hz),
the line frequency must be set manually here to make Epsilon be the ratio of line frequency to the output
word rate (OWR). This ensures the accuracy of the quadrature power (Q1, Q2) and the reactive power
(Q1
AVG
and Q2
AVG
) calculations. Refer to the CS5480 data sheet for more details.
2.7.6 Temperature Result
The Temperature field displays the CS5480’s die temperature in the top right corner of the Conversion
window.
2.7.7 Samples to Average
The Samples to Average field allows the user to average a number of measurement results.
