Introduction
1
The Southwire 13090T wirelessly transmits data to the MApp™ mobile app
via Bluetooth
®
technology allowing you to view, save, organize and share
datalogs and take measurements from a safe distance. Visit
nextgenmeters.southwiretools.com for mobile app download information.
Functions include AC/DC voltage and current, resistance, continuity,
capacitance, frequency, duty cycle, temperature, and diode test. True RMS
readings provide accurate AC measurements and a Low Z setting eliminates
false readings caused by “ghost” voltages. The 13090T 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.

Maintenance
This Multimeter is designed to provide years of dependable service, if the following care
instructions are performed:
1. KEEP THE METER DRY. If it gets wet, wipe it off.
2. USE AND STORE THE METER IN NORMAL TEMPERATURES. Temperature extremes can
shorten the life of the electronic parts and distort or melt plastic parts.
3. HANDLE THE METER GENTLY AND CAREFULLY. Dropping it can damage the electronic
parts or the case.
4. KEEP THE METER CLEAN. Wipe the case occasionally with a damp cloth. DO NOT use
chemicals, cleaning solvents, or detergents.
5. USE ONLY FRESH BATTERIES OF THE RECOMMENDED SIZE AND TYPE. Remove old or
weak batteries so they do not leak and damage the unit.
6. IF THE METER IS TO BE STORED FOR A LONG PERIOD OF TIME, the batteries should
be removed to prevent damage to the unit.

Auto Power Off
To conserve battery power, the meter automatically turns off after approximately
15 minutes. To disable Auto Power Off, set the rotary function switch to the Off
position. Press and hold the MODE button while setting the rotary
function switch to the desired function.
Release the MODE button when the symbol no longer appears on the LCD

Operation
1. Set the rotary function switch to
the Low Z position.
2. Press the MODE button to select
AC or DC voltage. The AC “~” or
DC “ ” symbol will appear on
the LCD display.
3. Insert the black test lead into
the COM input jack and the red
test lead into the V input jack.
4. Touch the test leads to the circuit
under test. If measuring DC
voltage, touch the red test lead to
the positive side of the circuit and
the black test lead to the negative
side of the circuit.
5. Read the voltage on the LCD display.
Low Z is used to check for “ghost” voltage. Ghost voltages are present when
non-powered wires are in close proximity to powered wires. Capacitive coupling
makes it appear that non-powered wires are connected to a real source of
voltage. The Low Z setting places a load on the circuit, which greatly reduces
the voltage reading when connected to a ghost voltage.
Low Z AC/DC Voltage
Observe all safety precautions when working on live
voltages. Do not connect to circuits that exceed 300V when the meter is set
to Low Z. Do not use Low Z when testing circuits that could be harmed by
this function's low input impedance.

on the LCD display.
3. Insert the black test lead into the COM input jack and
the red test lead into the Ω input jack.
4. Touch the test lead probes to the diode under test.
5. Forward voltage will indicate
0.4 to 0.7 on the display. Reverse
voltage will indicate “OL”. Shorted
devices will indicate near 0 and
an open device will indicate “OL”
in both polarities.

Operation cont.
1. Set the rotary function switch to
the HZ % position.
2. Press the MODE button to select
frequency or % duty cycle. The
“Hz” or “%” symbol will appear
on the LCD display.
3. Insert the black test lead into the
COM input jack and the red test
lead into the V input jack.
4. Touch the test lead probes to the
circuit under test.
5. Read the frequency or % duty cycle
on the LCD display.
Frequency and % Duty Cycle Measurements
Observe all safety precautions
when working on live voltages.
WARNING:
1. Set the rotary function switch to
the position.
2. Press the MODE button until the
“Ω” symbol appears on the LCD
display.
3. Insert the black test lead into the
COM input jack and the red test
lead into the Ω input jack.
4. Touch the test lead probes to the component under
test. If the component is installed in a circuit, it is
best to disconnect one side before testing to eliminate
interference with other devices.
5. Read the resistance in on the LCD display

Operation cont.
1. Set the rotary function switch to
the 10A position.
2. Insert the black test lead into the
COM input jack and the red test
lead into the 10A input jack.
3. Remove power from the circuit
under test, then open up the
circuit at the point where you
wish to measure current.
4. Touch the test lead probes in
series with the circuit being
measured. Touch the red probe
to the positive side of the circuit
and touch the black probe to the
negative side of the circuit.
5. Apply power to the circuit.
6. Read the current on the LCD display.
DC Current Measurements
Observe all safety precautions when
working on live circuits. Do not measure current on circuits
that exceed 600V. Measurements in the 10A range should
be limited to 30 seconds maximum every 15 minutes.
