Notes:
1 Typical at full range reading and voltage across the input terminals.
2 In 10 A range, > 10-20 Aac is readable for 20 seconds maximum with audio warning.
3 Input Current < 3 A RMS.
4 Input Current > 35 μA RMS.
5 Accuracy specified at input >5% of range and >1 A for 10 A range except other specified.
