TROUBLESHOOTING
CERTIFICATION EXAM
QUESTIONS AND
ANSWERS 2026 - 2027
Why is testing continuity important in troubleshooting? - ANSWERS-
Testing continuity can easily check to see if a part of a circuit has an
open.
What is a volt spike, and why is it dangerous for a troubleshooter? -
ANSWERS-A volt spike is a sharp spike in voltage in a circuit. It can
cause a short in the DMM which leads to an arc blast: when air ionized
and explodes.
What is the point of DMM category ratings? - ANSWERS-To limit arc
blasts by rating DMM's on how much voltage one can handle from a
volt spike.
Which organization created the category ratings for DMMs, and what
standard is it? - ANSWERS-The International Electrotechnical
Committee; this standard is known as IEC 1010.
How many DMM category ratings are there? - ANSWERS-Four.
