Attention:

1，999mA,10A,20A,the shunt is built in.

2，More than 20A ,you must use a shunt to work,even 0.1A, or it will be burnt.

3，More than 20A,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.

Technical Parameters: Supply voltage： DC4.5 ~ 30V（Note:The maximum input voltage can not exceed 30V, or be burnt.） Operating current： <20mA Test current:  DC0-20A Dimension:48*29*21 mm Mounting hole:45.5*26.5mm Display mode: 0.56 "LED with red/blue digits Measurement accuracy: 1% (± 2 digits) Measurement rate: ≥ 500mS / time Features:
