First, users should place a ammeter into the DC power circuit by series connection,

and adjust DC voltage till get the required current. Take the ammeter out.

Both HS and LD wires should be as short as possible. Every testing leads, especially

HS and LD, should use shielded wires.(Bold lead in the picture)
