Introduction
1
The Southwire 13050S functions include AC/DC voltage and current,
resistance, continuity, capacitance, frequency, duty cycle, tempera-
ture, and diode test. The 13050S also offers the added convenience
of a built-in LED flashlight. This meter is fully tested and calibrated
and, with proper use, will provide many years of reliable service.
WARNINGS
• Read, understand and follow Safety Rules and Operating Instructions in
this manual before using this meter.
• The meter’s safety features may not protect the user if not used in
accordance with the manufacturer’s instructions.
• Ensure that the test leads are fully seated in the input jacks and keep
fingers away from the metal probe tips when taking measurements.
• Before changing functions using the selector switch, always disconnect
the test leads from the circuit under test.
• Use only UL listed test leads with the proper safety category rating.
• Comply with all applicable 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 30 V AC rms, 42 V AC peak,
or 60 V DC pose a shock hazard.
• Do not use if the meter or test leads appear damaged.
• Verify operation before using meter by measuring a known live voltage.
• Do not use the meter in wet or damp environments or during electrical
storms.
• Do not use the meter near explosive vapors, dust or gasses.
• Do not use the meter if it operates incorrectly. Protection may be
compromised.
• Do not operate meter while Low Battery warning is on. Replace
batteries immediately.
• When replacing the battery or fuses, be sure to secure the battery
compartment door firmly to maintain the waterproof and dust proof
integrity of the meter. Loose or overtightened screws, or an improperly
seated o-ring may compromise the meter's water and dust ingress
protection.
• Do not apply voltage or current that exceeds the meter’s maximum
rated input limits.
