DANGER
The maximum rated working current is 2 ADC/AC. Attempting to input
current in excess of the maximum rating could destroy the product
and result in personal injury or death.
Never apply voltage to A-terminal. Doing so may damage the product
and result in personal injury. To avoid electrical accidents, remove
power from the circuit before measuring.

NOTE
After measuring large current, the terminal may become hot, producing
thermoelectric power that may cause incorrect measurement results.
Therefore, after measuring large current, wait a moment before measuring
again.
