I'm ready but too much sources

 Hi there all 

i just fnish to build the emonbase and the emontx 

I'll use for now just one ct (ct2) in order to test.

I just download the https://github.com/openenergymonitor/emonTxFirmware/blob/master/emonTx_1CT_Voltage/Emon.cpp

and upload in the emontx, but on the serial monitor i see a lot of strange values:

0.02 0.08 0.42 0.20 0.29

0.02 0.08 0.40 0.20 0.29

0.02 0.07 0.39 0.19 0.28

0.02 0.08 0.41 0.20 0.29

0.03 0.09 0.43 0.20 0.31

0.03 0.09 0.44 0.20 0.30

0.03 0.09 0.43 0.20 0.30

I use the arduino 1.0 ... so my question is, is the emonTx_1CT_Voltage the right one ? 

Here is the output of the emoncms:

rf_fail 2s ago 0

ct1 2s ago 22216

battery 2s ago 15592

 

Thanks in advance

Denis

 Are using using an AC-AC voltage adapter? If not then you should use emonT singleCT example.

Glyn - can you advise where you got the latest lot of AC/AC adapters from? Farnell have stopped stocking them, or did you buy them out...... ;)
Have seen a couple of 1000mA equivalents - does any code need changing if I get these? Im really keen to get as accurate a reading as possible.

We have plenty in stock. You can use emonTx with CT only to measure current and calculate apparent power.

 Hi Glyn, thanks for the help 

...well i don't use the AC-AC adapter, i don't want to use it for the moment 

I just program the emonTX and now i talìke this output:

 

 

49

39

44

47

44

47

44

45

30

44

47

 

I try in this time to consum +2000watts or 0 watts ... but the number is he same. 

I try also the ct1 and also the ct2 ... 

 

What i don't understant is if this is normal or i wrong something. 

Thanks agian

Re: I'm ready but too much sources

 Is there a source in order to calibrate the emontx please ? 

The one that i found is work with an arduino... 

Thanks again 

Denis
