Re: [SOLVED] 100A DC Current Sensor - Can't get an accurate reading

More woes, kind of a heads up to others, and wondering if the all knowing mparadis has any thoughts on this :). I did eventually calibrate using a 1011 interface kit (https://www.phidgets.com/?tier=3&catid=2&pcid=1&prodid=4) on my laptop. Everything was honky dory. Then I moved my super ...

Re: 100A DC Current Sensor - Can't get an accurate reading

It is 100% as you say :) I always do a lot of research before asking for help and this was no exception. Several factors got me confused here. the port reading from 0 to 1000 meaning 0V to 5V the middle point of 2.5V meaning 0A instead of the intuitive 0V=0A the fact that indeed, the sensor is not c...

Re: 100A DC Current Sensor - Can't get an accurate reading

There is the terrible possibility that I misinterpreted 2.5V being erroneous for 0A when in fact, it's right in the middle for a sensor which covers negative Amp values... Your test proves that. I'll try this shortly, today is sunny so fluctuations in current will not get lost in the noise. I'm cros...

Re: 100A DC Current Sensor - Can't get an accurate reading

Well that's really good to know (that conversion must be included in the formulas I grabbed for the other sensors). But it is as you say, the reading isn't accurate in that it remains the same no matter what I put through it. It's always something very close to 534. With wire, without wire. I grabbe...

Re: 100A DC Current Sensor - Can't get an accurate reading

Thanks for the idea, I can't tell if they are missing not knowing what they are but the ones I have look exactly the same (https://i.imgur.com/jRp8YrJ.jpg). This morning I plugged in the other 1145 with the other 3588. Same result. Even with no wire running through the 3588. It's worth saying I had ...

[SOLVED] 100A DC Current Sensor - Can't get an accurate reading

Hello, well not a whole of of folks seem to be using this sensors so I hope someone else out there has the answer. I just acquired a couple of these guys: https://www.phidgets.com/?tier=3&catid=16&pcid=14&prodid=439 which I paired with these: https://www.phidgets.com/?tier=3&catid=49...
