Wiring:

Black line (thin): power supply-

Red line (thin): power supply+

Black line (thick): COM, common line (measuring)

Red line (thick): I+, measurement current input+ (in series with measurement supply)

Yellow line (thin): V+, measurement voltage input+

Notice:

The supply voltage between the thin red and thin black lines must be within DC 3.5-28V

The ammeter can only be connected to the negative of the device under test

When the black thin line is vacant, it is recommended to use insulating tape around the exposed part of the wire, to

prevent short circuits.

If it is just used as a voltmeter, it is recommended that the yellow line and the black lines be connected

together, to prevent the ammeter digital flashing.
