Introduction1The 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.

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. WARNING: V-+-+-+12Operation cont.1. Insert the black test lead into the negative COM input jack.2. For current measurements up to 10A, set the rotary function switch to the 10A position and insert the red test lead into the 10A input jack.3. For current measurements up to 600mA, set the rotary function switch to the mA position and insert the red test lead into the µA mA input jack.4. For current measurements up to 6000 µA, set the rotary function switch to the µA position and insert the red test lead into the µA mA input jack.5. Press the MODE button to select AC or DC current. The AC “~” or DC “ ” symbol will appear on the LCD display.6. Remove power from the circuit under test, then open up the circuit at the point where you wish to measure current.7. Touch the test lead probes in series with the circuit being measured. For DC current, touch the red probe to the positive side of the circuit and touch the black probe to the negative side of the circuit.8. Apply power to the circuit.9. Read the current on the LCD display.AC/DC Current MeasurementsMEASUREMENTS UP TO 10A Observe all safety precautions when working on live circuits. Do not measure current on circuits that exceed 1000V. Measurements in the 10A range should be limited to 30 seconds maximum every 15 minutes.
