The Southwire 41150S Voltage Tester provides a simple and fast
method of testing AC and DC voltage up to 240 volts. It also
tests GFCI protected outlets. This meter is fully tested and,
with proper use, will provide many years of reliable service.
WARNINGS
• Read, understand and follow the Safety Rules and Operating
Instructions in this manual before using this instrument.
• The tester’s safety features may not protect the user if not
used in accordance to the manufacturer’s instructions.
• Keep fingers away from the metal probe tips when taking
measurements.
• Comply with all safety codes. Use approved personal
protective equipment when working near live electrical
circuits - particularly with regard to arc-flash potential.
• Use caution on live circuits. Voltages above 30V AC RMS,
42V AC peak, or 60V DC pose a shock hazard.
• Do not use if the instrument or test leads appear damaged.
• Verify tester’s operation by measuring a known voltage.
• Do not use the tester in wet or damp environments or during
electrical storms.
• Do not use the tester near explosive vapors, dust or gasses.
• Do not use the tester if it operates incorrectly.
Protection may be compromised.
• Do not apply voltage that exceeds the tester’s maximum
rated input limits.

Safety Category Ratings
The measurement category (CAT) rating and voltage rating is determined by a combination of the meter,
test probes and any accessories connected to the meter and test probes.
The combination rating is the LOWEST of any individual component.
