EKM Metering

Hi, I'm using the EKM-OmniMeter I v.3 to measure a 3-phase 3-wire system. However, when I read the values on the display, it's showing different measures from the ones I can get with a multimeter. I should be reading ~480V for both V1 and V3, but it's showing 353.6 for V1 and 489.9 for V3. Why do yo...

HI Jameson,

Thanks for the tips, the cable is now working!

Hi Jameson, Thanks for replying, So, I checked the COM ports; they are ok. I tried to use some resistors, biasing and termination. I only have 350Ohm with me right now,, so I did something like this: 2x 350Ohm (=700Ohm) series connected from B- to +5 2x 350Ohm (=700Ohm) series connected from A+ to G...

Hello, I recently got one EKM Metering for me, the I v.3 I already had a USB to RS 485 converter, which I believe use the same technology from yours: http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_USB_RS485_CABLES.pdf Says in the datasheet thar: Orange Data+(A) Bi-Direction Data + (A...
