Introduction
The Southwire 16020N functions include AC/DC voltage and current,
resistance, continuity, capacitance, frequency, duty cycle and diode test. A
built-in flashlight and a non-contact AC voltage detector offfers added
convienience. 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.
• 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.
• 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.
• Do not apply voltage or current that exceeds the meter's maximum
rated input limits.
