Din rail s0 meter problems

I have bought a din rail with s0 pulse output, because solar watthours measuring is not a good option with current clamps.
I have a problem. The manual says, the s0 pulse voltage should be between 12 and 27 volts.
But it is 3.23. I have measured, but everything works fine (in my opinion)
The voltage is 3.23 and when there is a pulse, it closes and the voltage is 0.
The count should be good.

BUT...

On my din rail and on my solar converter, the same watthours... (thats perfect)
But the din rail and the dash is not the same!
Dash is around 14% more kwh, than the din rail meter?!?!
So the pulses are given 1000 a kwh, so it should be set 1 in dash.
What could this be? Is the voltage too low?

No. As far as I know it takes the equation of the current x the voltage to get watts.

I have the count now on 0.877,
But it seems that this doesn't work.
1/1.14=0.877
But I don't have any graphics now.

Does the log still show pulses.

How can I look in log?

Bazzle, you're great. I found the problem, but now i'm looking for an answer.
The counting of the pulses are not good...
32567, 32568, 32569, 32571. The last digit goes like:

1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,9,1,2,3,4,5,6,7,9,0,1
Her above I misses 0,8,0,8
Thats quit a lot.
What is the problem? When it count it is GOOD (the timing). But the counting is not good! It's like a 1 year old kid counting....

Anybody knows?
I try another port of the flukso, but is this a flukso fault?

1/ A r232 firmware will only report pulses on integer values of the counter. This will not be the case anymore in the r24x release.
2/ What meter constant is printed on the DIN-rail meter?

hanskraayeveld's picture

230v +-30% 50/60hz 1000 imp kwh

When did the new release come?

Sorry, i meant the current firmware of course ;-)

If your DIN rail meter has a meter constant of 1000imp/kWh, you should set your sensor to 1Wh/pulse. If spurious pulses are counted, double-check the wiring. A second action you could take is to connect the DIN rail meter to a different port and check again.

Bart,

Could you please take a look at my topic: flukso counting problems?
Because my port 2 is not good. Can I use in my case port 6? How can we solve it or get around it?
Or can I fix it... Or replace something...

Thanks
