OSCILLOSCOPE SAFETY
Before test-driving your OPTAscope 81M, it is important for you to be aware of the
general safety guidelines for working with oscilloscopes. Working with oscilloscopes
requires you to work on circuits with live voltage. Live voltage can and does KILL
people every day. It is your responsibility to learn the following safety guidelines and
practice them faithfully while working with live circuits. Failing to do so can result in
equipment damage, and severe personal injury or death. Below you will find a list of
safety rules that you are to use as a guideline while working with live circuits and the
OPTAscope.

ALWAYS disconnect the power supply to the circuit you are measuring before
walking away from your workstation.
Remove metallic jewelry and watches before starting.
Make sure your hands are clean and dry while working with the OPTAscope.
Work upon an anti-stat pad that is properly grounded.
Keep your work area free from food and beverages.
Do not attempt to measure any voltage that could be 20 Vpp or higher.
If anything you are working on gets hot, turn it off immediately.
