What is a multimeter?
What is a multimeter?
A device that measures electrical quantities like voltage, current, and resistance.
What is a continuity test?
What is a continuity test?
A test that checks if there is a complete path for electricity to flow. This means no breaks or interruptions in the circuit.

Study Notes
Multimeter 1
-
Aim: Use of multimeter, including continuity testing, voltage measurements (DC and AC), and checking components
-
Continuity Test: Checks if a circuit is complete. A beep indicates continuity (low resistance). No beep means discontinuity (high resistance)
-
Multimeter Functionality: A single device acting as ammeter, voltmeter, and ohmmeter. It can measure both alternating and direct current/voltage.
-
Range Adjustment: Adjusting the dial changes internal shunt resistance in the ammeter circuit, and internal series resistance in the voltmeter circuit
-
Apparatus: Multimeter, cartridge fuse, wire, various cells (Leclanche, Danielle, dry), step-down transformer
-
DC Voltage Measurement:
- Set the dial to DC Voltage mode
- Connect the red probe to the positive terminal and the black probe to the negative terminal
- The display shows the voltage reading.
-
AC Voltage Measurement:
- Set the dial to AC Voltage mode
- Insert probes into the secondary terminals of the step-down transformer
- Record the reading
Procedure (General)
- Continuity Test:
- Set the multimeter to continuity mode.
- Touch the probes together and listen for a beep. A beep indicates the multimeter is operational. -Place probes at two points on a circuit/wire to test whether or not there is a connection/continuity
- Checking a Fuse: Test the fuse for continuity
- Measuring Cell Voltage: Measure the voltage across various cells
- Measuring Transformer Voltage: Measure the AC voltage across the secondary of a step-down transformer
Results
- Continuity: Record whether the tested components (fuse, wires) have continuity or not
- DC Voltage: Record voltage readings for various cells
- AC Voltage: Record AC voltage readings across the secondary tapping of the step-down transformer
