Introduction
The oscilloscope, which displays voltage versus time, is an indispensable tool for testing and
troubleshooting circuits and taking electrical measurements. This tutorial will explain how to set
up the oscilloscope and take basic measurements.
Getting Started
Do the following steps to set up the oscilloscope.
1. Turn on the oscilloscope by pressing the power button located in the lower left-hand
corner. Wait for scope to boot-up. When a message shows up on the screen, press the
MENU OFF button.
2. When the oscilloscope powers up, it uses the settings that were in place when it was last
powered down. To return the oscilloscope to the factory settings, press the Save/Recall
button. Then press the button under the screen labeled Recall Factory Setup. Next press
the button on the right of the screen labeled OK Confirm Factory Init.
