Introduction
The Southwire 22070T True RMS Clamp Meter measures AC/DC
current, AC/DC voltage, resistance, capacitance, frequency, duty
cycle, and temperature. It also tests diodes, continuity, and non-con-
tact AC voltage. This meter is fully tested and calibrated and, with
proper use, will provide many years of reliable service.

• Read, understand and the follow 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 selector 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 when working on or near bare conductors or bus bars.
• 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 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.
• Do not operate meter while Low Battery warning is on.
Replace batteries immediately.
• Verify meter's operation by measuring a known voltage.
• Do not apply voltage or current that exceeds the meter’s
maximum rated input limits.

Maintenance
This Clamp Meter 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.

Operation cont.
Insulation type and thickness, and distance from the voltage
source and other factors may effect operation. It is always best to use other
methods to verify live voltage if there is any uncertainty.
NOTE:
The detector is designed with high sensitivity. Static electricity
or other sources of energy may randomly trip the sensor. This is normal
operation.
NOTE:
Battery Replacement
1. Remove the two Phillips screws.
2. Open the battery compartment.
3. Replace battery with one
9-volt battery.
4. Re-assemble the meter.
To avoid electric shock, disconnect the test leads
from any source of voltage before removing the battery cover.
DO NOT operate this meter until the battery cover has been properly secured.
WARNINGS:
To avoid electric shock, do not operate your meter
until the battery and fuse covers are in place and fastened securely.
WARNING:
TO AVOID
ELECTRICAL SHOCK,
REMOVE TEST LEADS
BEFORE OPENING CASE
OR BATTERY DOOR.

Temperature Measurements
Operation cont.
1. Set the rotary function switch to the Temp 0F, 0Cposition.
2. Push the to select readings in °F or °C.
3. Connect the Temperature Probe to the Banana Plug
Adapter. Insert the adapter into the negative COM
and the positive Temp input jacks, making sure to
observe the correct polarity.
4. Touch the tip of the Temperature Probe to the part you
wish to measure. Keep the probe touching the part
under test until the reading stabilizes (about 30 secs).
5. Read the temperature on the LCD display.
To avoid electric shock,
remove the temperature probe before changing to
another measurement function.
WARNING:
To avoid electric shock, do not
let the temperature probe contact live circuits.
WARNING:
1. Non-contact voltage operates when the
rotary function switch is in any position
except OFF.
2. Slowly move the detector probe closer to
the conductor being tested.
3. If AC voltage is within the specified range
is present, the detector light will illuminate.
Non-Contact AC Voltage Detector (100 to 600V AC)
Risk of Electrocution. Before use, always
test the Voltage Detector on a known live circuit to verify proper operation.
