1, this range is DC Ammeter DC0-9.99A.
2, the current direct input table without shunts and transformers.
3, you must use an external power supply, the power supply voltage is DC7-20V.
4, special attention: the power of the input can not be negative (common ground)! !
This is because the table size limits, can not give the chip negative power supply,
it is not common ground. Common ground will cause the displayed incorrectly can cause serious damage to the meter!
