Checklist

The fundam­entals of electrical safety can be overlo­oked, especially by seasoned electr­icians. It's worth reviewing a few safety tips, both for the novice electr­ician and the veteran.

Checklist

Use a meter that meets accepted safety standards for the enviro­nment in which it will be used.
Use a meter with fused current inputs and be sure to check the fuses before making current measur­ements.
Inspect test leads for physical damage before making a measur­ement.
Use the meter to check continuity of the test leads.
Use test leads that have shrouded connectors and finger guards.
Use meters with recessed input jacks.
Select the proper function and range for your measur­ement.
Be certain the meter is in good operating condition.
Follow all equipment safety proced­ures.
Always disconnect the "­hot­" (red) test lead first.
Don't work alone.
Use a meter that has overload protection on the ohms function.
When measuring current without a current clamp, turn the power off before connecting into the circuit.
Be aware of high-c­urrent and high-v­oltage situations and use the approp­riate equipment, such as high-v­oltage probes and high-c­urrent clamps.
