Introduction
WARNINGS
1
The Southwire 10030S multimeter measures AC and DC voltage, DC
current, and resistance. It also tests continuity, diodes, and batteries.
Readings are displayed on a large backlit LCD. This meter is fully
tested and calibrated and, with proper use, will provide many years
of reliable service.
• Read, understand and follow the 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 to 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 rotary function 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 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 meter or test leads if they appear damaged.
• Do not use the meter if it operates incorrectly. Protection may
be compromised.
• Verify meter’s operation by measuring a known 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.
• Replace the battery as soon as the low battery warning appears.
