IMPORTANT SAFETY INFORMATION
Safety Warnings and Precautions
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
1. Electrical shock can cause death or injury! NEVER
TOUCH exposed conductors of electricity.
2. Inspect the Tester before use.
3. Do not use the Tester if:
a. The Non-Contact Tip is damaged in any way.
b. Non-Contact is dirty.
c. Near any explosive gasses or fumes.
d. Any abnormal operation is detected.
(If in doubt about the condition of
the Tester, have it serviced.)
4. Use caution when working near voltages above
30 VAC rms, 42 VAC peak, or 60 VDC. Voltages
this high present a risk of electric shock.
5. Avoid electrical shock. Use extreme caution when working
near uninsulated conductors or bus bars. Prevent body
contact with grounded surfaces such as pipes, radiators,
ranges, and cabinet enclosures when testing voltages.

6. Remove metal jewelry and watches
before working near batteries.
7. Observe work area conditions. Do
not test voltages in damp or wet
locations. Don’t expose to rain.
Keep work area clean and well lit.
8. Keep children away. Children must

11. People with pacemakers should
consult their physician(s) before
use. Electromagnetic fields in close
proximity to heart pacemaker could
cause pacemaker interference
or pacemaker failure.
12. Do not test voltage on circuits
higher than rated capacity.
13. Store idle equipment. When not
in use, Testers must be stored in a
dry location to decrease exposure
to moisture. Lock up Testers and
keep out of reach of children.
14. Dress properly. Protective,
electrically nonconductive
clothes and nonskid footwear are
recommended when working.
15. Wear ANSI-approved safety
goggles during use.
16. Only use accessories intended

18. Avoid damaging Tester. Use only
as specified in this manual.
19. Do not disassemble Tester; take
it to a qualified technician when
service or repair is required.
Incorrect reassembly may result
in a risk of electric shock or fire.
20. Have the Tester calibrated by a
qualified technician every year.
A Tester that is not calibrated yearly
may not yield accurate results.
