The display will show the number of Coulombs deposited into the instrument either by current through a resistance or from a capacitor or from a source of static electricity like a charged plastic rod. A electroscope will deflect its vane but this instrument shows the charge digitally in Coulombs up to 1.999 nano Coulombs.
