Attention:

1，999mA,10A,the shunt is built in.2，More than 10A ,you must use a shunt to work,even 0.1A, or it will be burnt.3，More than 10A,the shunt is not built in,you need to buy it separately.  (1)If you have a shunt , please note your shunt specification (standard is 75mV, if no notes, all according to 75mV delivery)  (2)If you don't have a shunt, please order the corresponding shunt, we will not notice at the time of shipment.4，Because the 24V battery charge full of floating voltage may be more than 30V, so "no" recommended direct use 24V battery.5，In the following circumstances, it is strongly recommended to choose: isolation meter (isolated power supply meter): (1) When two or more meters are installed on a device.  (2) Can not be isolated power supply.
