Precautions for measuring DC and AC current with digital multimeter
1. The current greater than 10A cannot be measured in the 10A gear; the current greater than 400mA cannot be measured in the uA and mA gears, otherwise the fuse may be blown and the meter may be damaged.
2. When measuring high current, each measurement time should not exceed 10 seconds, and the interval time between each measurement should be more than 15 minutes.
3. After the measurement is completed, immediately disconnect the test leads from the circuit under test.
