Multimeter Measurements
Measuring Resistance Values
Making a Diode Measurement
Making Continuity Tests
To perform a Continuity Test, do the following:
By pressing the DMM/OSC key the oscilloscope will switch to the Multimeter mode.
The screen will display the multimeter windows, and, at the same time, prompt to
correctly insert the test leads. At this time press any key to enter the multimeter
measurement mode.
To measure a resistance, do the following:
