When measuring current, for 10 A to 15 A, the measuring duration should not be over
2 minutes within 10 minutes, and in this 10 minutes, no other current should flow
through except within the measuring duration; for 15 A to 20 A, the measuring
duration should not be over 10 seconds within 15 minutes, and in this 15 minutes, no
