Re: Precision of Measurements

You are looking at this part of the spec sheet: http://forum.ekmmetering.com/download/file.php?id=225&sid=1bc2e6469bb309bea73b615660002030 Input is the percentage of the CT Rating, Correct so when a 200A CT is measuring 50% the current passing through it is 100A so for example when the 200 amp CT i...

Re: CT Reference Voltage

Im not sure to be honest. I have not found ohms to be a reliable method of determining if a CT is bad or not This why the CT's were first tested using a known resistive load and as I pointed out in my post the resistance value is not the ideal method but it is the next best thing and certainly star...

Alternative CT Checking Method

So I've partly arrived at a conclusion for the incorrect values that are being reported by the EKM V4, not totally solved ATPIT. I have several CT's that appear to be outside a reasonable value tolerance. When they are attached to a common load rail the instantaneous values are considerably differen...

Re: CT Reference Voltage

No Issue at all just trying to get some information so that I can better determine where and why I have some discrepancies with Omnimeter V4 readings especially the Current readings (Amps), which have absolutely nothing to do with sampling rate, cycle or sequencing as I can calculate them out correc...

Re: New Wifi/lost communications and iSerial login failure

Is your new router using the same IP Network Addressing as your previous router? Example is it using 192.168.2.xxx or is it using different addressing like 192.168.0.xxx or 10.10.0.xxx etc.? In which case you might be best to perform a reset on the iSerial and follow the original installation instru...
