Digital Multimeter, Capacitance & Auto Power Off

Description

The Digital Multimeter, Capacitance & Auto Power Off, also known as a handheld digital multimeter, electronic multimeter or AC/DC electrical testing meter, is designed for measuring electrical parameters during laboratory experiments, circuit investigations and general electrical testing. Supplied by IEC (Industrial Equipment & Control Pty Ltd), this compact multimeter combines voltage, current, resistance and capacitance measurement with several electronic component testing functions. It is suitable for educational laboratories and electrical work within its specified operating limits.

The instrument measures alternating current (AC) and direct current (DC) voltage, allowing students and laboratory personnel to investigate potential differences across electrical components. Users select the appropriate measurement function before connecting the test leads. The multimeter also measures AC and DC current up to 20 A. This higher current capability provides an additional option for experiments involving suitable electrical loads, subject to the meter’s input protection and permitted measurement duration. For smaller circuits, the instrument supports current measurements down to 1 µA. This allows users to investigate low-current electronic applications, including suitable semiconductor and experimental circuit arrangements.

The resistance measurement function covers values up to 200 MΩ, supporting investigations involving resistors, conductor properties and electrical continuity. Resistance measurements must be performed on de-energised circuits. The instrument also measures capacitance up to 20 µF, allowing students to examine capacitors used in basic electronic circuits. Capacitors must be safely discharged before testing. Additional functions include diode testing and transistor gain (hFE) measurement. These features help students investigate semiconductor components and understand their roles in electronic switching and amplification circuits.

An audible continuity beeper provides an indication when a suitable electrical connection is detected. This simplifies routine wiring checks and circuit construction activities. The large digital LCD displays the measured value and selected unit, helping users identify the electrical quantity being tested and interpret results correctly. A dedicated power ON/OFF button provides convenient operation. The automatic power-off function helps conserve the standard 9 V battery when the instrument is left inactive. The multimeter measures 170 × 85 × 35 mm and weighs approximately 120 g, making it convenient for laboratory benches, educational workstations and portable electrical investigations.

The instrument is supplied with one red and one black test lead, providing the connections required for suitable voltage, current and component measurements. IEC also includes this multimeter in selected electricity teaching kits used to introduce students to AC and DC electrical theory, circuit measurements and electronic components. Safety Precautions: Select the correct measurement function and input terminals before testing. Never measure current by connecting the meter directly across a voltage source. Disconnect circuit power before resistance, capacitance or continuity testing. Verify the meter’s measurement category, voltage rating and 20 A input limitations before use. Each unit includes one IEC Digital Multimeter and two test leads. A standard 9 V battery is required, but its inclusion has not been confirmed.
