Study Notes

A digital ohmmeter's operation is based on the conversion of a resistance measurement into a digital display.
A key feature of digital multimeters is their ability to provide accurate measurements over a wide range of values.

An oscilloscope connects in a circuit using a probe, which is usually a voltage-measuring device.
The voltage section of an oscilloscope measures the amplitude of the waveform.
The time base of an oscilloscope measures the time duration of the waveform.

The vertical position of the waveform on an oscilloscope is adjusted using the vertical position control.
The display on an oscilloscope represents the waveform of the measured signal.

The best way to troubleshoot circuits is by first understanding the circuit's operation and then using an oscilloscope to measure the voltage at different points.
A digital multimeter's diode test function is used to test semiconductor devices.

Oscilloscope waveforms can be downloaded into a computer for further analysis.
When using a grounded probe on an oscilloscope, the probe should be connected to the ungrounded circuit conductor to ensure safety.
