Oups ! It wrotes Atlas but it is effectively Atlys that we must read.

 

Thank you Alex. I already read informations in the Reference Manual. Actually, we need more accurate informations like sampling frequency for instance.

 

Do these informations exist somewhere?

The Atlys power monitor tool in Adept application samples at 5 time / second which is close to the conversion rate of the ADC, with resolution/LSB of ~2.5 mA, range 160 A

See default mode of http://cds.linear.com/docs/en/datasheet/2481fd.pdf

 

If you want different measurement you can create custom application/script using the Adept 2 SDK DMGT functions like:

int rgp[4];
int rgs[4];
double rga[4];

for(int i = 0; i < 4; i++){
    // conversion factor
    DmgtGetPowerSupplyProperties(hif, i, NULL, &rgp, NULL, NULL))
}

sampling_loop:
for(int i = 0; i < 4; i++){
    // raw ammeter data 
    DmgtGetPowerSupplyData(hif, i, NULL, &rgs, NULL, NULL, NULL)
    // convert to Ampere
    rga = 1.0*rgp*rgs/1000000;
}
