Re: Maximizing Precision

Thanks Doug, very helpful. I will switch over to the fixed output as I am not using the right CTs to get the 1600 pulses/kWh working anyway. Jameson, here is the test result you requested: Over a 60 second interval, I counted 59 flashes of the LED. According to RS-485 data for that same 60 second pe...

Re: Maximizing Precision

Hi Jameson, I've got the v.4 meter hooked up, and have jumpered terminals 15 and 11 to connect the variable rate output of the meter to its own pulse 1 input. I left all settings at default (including ratio of 1/800 for the pulse output because I didn't replace the CTs). I am getting unexpected resu...

Re: Understanding Max Demand

Again, thanks for this helpful information. It sounds like the max demand parameters aren't for me. I will investigate polling quickly to determine the max watts myself. Just to close the loop on the terminology, though, the term "max demand interval" is listed at the following link: http://document...

Re: Maximizing Precision

Thanks, this is very helpful. Multiple wraps through the CT won't work here because its 6 AWG wire and there's not enough space in the panel or CT for wrapping. It sounds like the v.4 is the way to go. Do you envision any problems if I use the v.4 to count its own pulses? I assume I can wire the set...

Understanding Max Demand

Could you post an explanation of the parameters "Max Demand Period" "Max Demand Interval" and the meaning of the Max_Demand data field in the meter response? I would like to poll the meter and receive back the maximum power (W) that was drawn since the last poll (or zero). However, it looks like the...

Maximizing Precision

Hi there, I am trying to monitor a circult several times per hour that has relatively low current draw for research purposes. I have the OmniMeter I v.3, but it only seems to report in 0.1 kWh increments, and my circuit can take several hours to increase by 0.1 kWh. This leads to several questions. ...
