Replacing 1m with 100k resistor will allow to measure 0 19 99v voltages with 0 01v 10mv accuracy.
Therefore if you short j1 you can use just two wires for measuring a voltage. To regulate fine sub range connect voltmeter to psu output set up voltage at about 9v and turn r9 until voltmeter and multimeter indications are equal. At the heart of most analog meters is a galvanometer an instrument that measures current flow using the movement or deflection of a needle.
Therefore if you short j1 you can use just two wires for measuring a voltage.
Dsn dvm 368 voltmeter module schematic it has three terminals. The needle deflection is produced by a magnetic. Wie man ein amperemeter einbaut und anschlisstachtung battarie abklemmen https www conrad de de amperemeter standard beleuchtungsfarben gelb rot gruen equu. A voltmeter is connected in parallel with a device to measure its voltage while an ammeter is connected in series with a device to measure its current.
