Introduction
WARNINGS
1
The Southwire 11050N autoranging multimeter measures AC/DC
voltage and current, resistance, capacitance, frequency, duty
cycle, and temperature. It also tests diodes, continuity, and
non-contact AC voltage. 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 VAC RMS,
42 V AC peak, or 60 VDC 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.

Operation
HOLD
The hold function freezes the reading in the display. Press the HOLD button
momentarily to activate or to exit the HOLD function.
DISPLAY BACKLIGHT
Press and hold the HOLD button for >1 second to turn on the display backlight.
The backlight will automatically turn off after 10 seconds. The display can also be
turned off manually by pressing and holding the HOLD button for >1 second.
MAX/MIN
Note: When using the MAX/MIN function in the Autoranging mode, the
meter will “lock” onto the range that is shown on the LCD display when
MAX/MIN is activated. If a MAX/MIN reading exceeds that range, an “OL”
indicator will be displayed. Select the desired range BEFORE entering the
MAX/MIN mode.
1. Press the MAX/MIN button to activate the MAX/MIN recording mode. The
"MAX" indicator will appear on the LCD display. The meter will display and
hold the maximum reading and will update only when a new “max” occurs.
2. Press the MAX/MIN button again and the "MIN" indicator will appear on
the LCD display. The meter will display and hold the minimum reading and
will update only when a new “min” occurs.
3. To exit MAX/MIN mode press and hold the MAX/MIN button for 2 seconds.
AUTORANGING/MANUAL RANGE SELECTION
When the meter is first turned on, it automatically goes into Autoranging. This
automatically selects the best range for the measurements being made and is
generally the best mode for most measurements. For measurement situations
requiring that a range be manually selected, perform the following:
1. Press the RANGE button. The “AUTO” display indicator will turn off.
2. Press the RANGE button to step through the available ranges until you select
the range you want.
3. To exit the Manual Ranging mode and return to Autoranging, press and hold
the RANGE button for 2 seconds.
Note: The Range button does not operate in Capacitance,
Frequency or Duty Cycle functions.
Note: MAX/MIN does not work on Capacitance,
Frequency or Duty Cycle functions.
