TCP0030A Accuracy Question

After reviewing the specifications on the TCP0030A, I noted that it has a DC accuracy of 1/1.5 percent. I'd like to know more about this. For example, when I measures something and it reads 1 mA, does it include the 1%?

Hi,

The TCP0030A accuracy specs are as follows:

Accuracy, typical
DC: ±1% of reading

DC to 60 Hz, ≤5 A: ±1%

60 Hz – 5 kHz, ≤5 A: ±1.5%

DC – 5 kHz, >5 A: ±1.5%

The % of reading implies an accuracy within a percentage of the measured value. For example, a DC signal at 1A would have a +- 1% accuracy, meaning it would be accurate within 10mA. That implies a range of 990mA to 1010mA for the true signal value. A 1A signal at 1kHz would have 1.5% accuracy, implying a range from 985mA to 1015mA.
