Hi all, just wanted to bring to someone’s attention a doc error that I encountered. I just wired up a Pi with a single-channel i2c current monitor and saw current measurements that didn’t make sense to me. I had the wire fed through the CT with the orientation following the direction of the arrow printed on the board- which also matched the diagram on p3 of the command reference guide at https://media.ncd.io/sites/2/20170721135041/Current-Monitoring-Reference-Guide-3.pdf . With this config the readings were about half of what I should’ve gotten from my sample load.
But then I found the single-page “Wiring Diagram” at https://media.ncd.io/sites/2/20170721135041/I2CCMAC_DLCT27C10.pdf . This shows the direction of power flow OPPOSITE of the arrow printed on the board (and also opposite of the Reference Guide). So I spun things around that way and VIOLA! It was as expected.
