Note :
1. Generally, the minimum measurable current value is 2% of the selected range. When selecting the current range (e.g. 1A, 5A... (100A, 200A, etc.), please try to choose the range close to the measured current value, so as to achieve the best measurement accuracy.
2. For the external shunt head, must be connected to the shunt can be energized! Remember!! If the shunt is not connected first, sometimes the input voltage of the op amp will be too high and the op amp will be burnt out!
3. The meter head cannot be powered by a 24V battery, because the 24V battery, full power, peak voltage will be higher than 30V, please remember!
