The first analog multimeter was invented by Donald Macadie, a British Post Office engineer, in the 1920s.
Macadie was frustrated with having to carry multiple tools for testing telecommunication circuits. He created a single device that could measure amperes (amps), volts, and ohms, which led to it being named the avometer.
The original avometer was bulky compared to today's digital multimeters, but it became more portable and featured additional ranges and functions by the 1930s.

Testing electronic components is crucial for several reasons:
- Ensuring Functionality: Testing verifies that components work as intended, meeting specifications for voltage, current, resistance, etc. This ensures the overall circuit or device functions correctly.
- Identifying Defects: Testing helps detect faulty components before they cause problems in the circuit. This prevents malfunctions, reduces repair costs, and improves product reliability.
- Quality Control: In manufacturing, testing ensures consistent quality across production batches. This helps identify and address manufacturing inconsistencies, leading to reliable products.
- Troubleshooting: Testing helps isolate the source of problems in existing circuits. By testing individual components, technicians can pinpoint the faulty element and replace it, minimizing downtime and repair costs.
- Design Optimization: Testing provides valuable data for circuit designers. By evaluating component performance under various conditions, designers can optimize circuit design, improve efficiency, and reduce power consumption.
- Safety: Testing ensures that components meet safety standards, preventing electrical shocks, fires, or other hazards caused by faulty components.
In short, testing electronic components is essential for ensuring product quality, reliability, safety, and efficient operation.
