About wiring:
Red line (thin): power supply plus
Black line (thin): power supply -
Red line (thick): PW plus , measuring terminal voltage input positive
Yellow line (thick): IN plus , current input
Black line (thick): COM, common measuring

Note:
The voltage between the thin red and thin black lines must be within DC 4.5-30V
The ammeter can only be connected to the device under test 10A below ammeter (include 10A) with built-in shunt
If you want to test the device above 10A, please remember connecting the external shunt
when the black thin line vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits
if just be used as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashing
