Best Practices for Live Measurements

Keep Your Eyes on the Job at Hand

Measuring live voltages and current in today’s high energy environments can result in a severe hazard to equipment and users if proper precautions are not applied. Given the risk of transients, surges, and old-fashioned human error, it always pays to follow safe work practices and use test instruments rated for the voltage or current you’re measuring.

Whenever possible, work on de-energized circuits and follow proper lockout, tag-out procedures. If you have to work on live circuits, following the steps below will improve your measurement practices and help reduce any hazard.
