\nTo measure resistance, voltage (AC\/DC), current (AC) and check continuity of a given circuit using multimeter.<\/p>\n
\nApparatus. Three carbon resistors, one standard resistance coil, a battery eliminator with tapping (2 V, 4 V and 6 V), a step down transformer (6-0-6 V) with two tapping (2 V and 4 V), a resistor of 100 ohm, a plug key and multimeter.<\/p>\n
\nMultimeter. It is a single measuring device acting as an Ammeter, a Voltmeter and an Ohmmeter. For this reason, it is also called AVO<\/strong> meter.
\nIt can measure alternating as well as direct current and alternating as well as direct voltage in addition to resistance. For this purpose its panel is divided into five different sections. There are many ranges in each section so that it can measure from micro (10-6<\/sup>) to mega (106<\/sup>) units. Rotation of a knob changes the section and the range in one section.
\n\u2014 Rotation of knob for change in ammeter range, brings shunt resistances of different values in circuit in parallel with the coil.
\n\u2014 Rotation of knob for change in voltmeter range, brings series resistances of different values in circuit in series with the coil.
\n\u2014 Rotation of knob for change in ohmmeter range, brings different resistances in circuit in series with the multimeter cell.<\/p>\n\n
