Apologies, waking up an old post...
Can anybody help translate MicSig's specified Accuracy, identical language for CP2100A & B. It's entitled "DC accuracy" but then uses "Apk" which I assume means "Amperes Peak", which wouldn't be DC.
DC accuracy (typical)
3%±50mA (10A) {I'm guessing this line is DC, on 10A range, but no equivalent for 100A range}
4%±50mA(100A,500mA~40Apk) {maybe AC accuracy if Amps peak is <40Amps, up to bandwidth limit .8 or 2Mhz}
15%(100A,40Apk~100Apk) {maybe AC accuracy if Amps peak is >40Amps, up to BW .8 or 2Mhz. saturation of steel core?? so reads lower than reality}
Your post is a year old, but I thought I'd reply.
The way I read it has nothing to do with AC current, but DC with possible transients.
DC accuracy (typical)
3%±50mA (10A) {DC accuracy on 10A range}
4%±50mA(100A,500mA~40Apk) {DC accuracy on 100A range, from 500mA to 40A}
15%(100A,40Apk~100Apk) {DC accuracy on 100A range, from 40A to 100A}
