FIRMWARE VERSIONS
Appendix D. 50/60 Hz Meter Operation
There are two versions of firmware for the meter due to the quasi-synchronous
sampling scheme employed by the dsPIC33F firmware. The design covers the
frequency of rated frequency ±2.5 Hz.
To change the rated frequency, just change the definition in the beginning of
cacul.h - #define STD_FREQ 50.0.
This is provided for download from Microchip’s website, file names and checksums
below.
At the same time you need to change the crystal to provide clock for metering IC.
