Introduction
1
The Southwire 14090T 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 14090T 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.

Operation cont.
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
between wires make 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 ghost voltage.
Low Z AC/DC Voltage
Observe all safety precautions when working on live
voltages. Do not connect to circuits that exceed 600V 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.
