IMPORTANT SAFETY INSTRUCTIONS
Hz
WARNING READ ALL SAFETY WARNINGS AND INSTRUCTIONS.
Failure to follow the warnings and instructions may result in electric shock, fi re and/or serious
injury, as well as instrument damage and/or damage to the equipment being tested.
Save these instructions - This operator’s manual contains important safety and operating
instructions for the MILWAUKEE Clamp Meters. Before using, read this operator’s manual
and all labels on the Clamp Meters.
DANGER
Never make measurement on a circuit in which voltage over AC600V exists. Use only leads
rated 600V or better.
Do not attempt to make measurement in the presence of fl ammable gasses. Otherwise, the
use of the instrument may cause sparking, which can lead to an explosion.
Transformer jaw tips are designed not to short the circuit under test. If equipment under test
has exposed conductive parts, however, extra precaution should be taken to minimize the
possibility of shorting.
Never attempt to use the instrument if its surface or your hand is wet.
Do not exceed the maximum allowable input of any measuring range.
Only test on unenergized circuits unless absolutely necessary.
Check tool functionality on a known circuit fi rst. Never assume tool is working. Assume circuits
are live until they can be proven de-energized.
Do not ground yourself while measuring. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators.
Never open the Battery cover during a measurement.
The instrument is to be used only in its intended applications or conditions. Otherwise, safety
functions equipped with the instrument doesn’t work, and instrument damage or serious
personal injury may be caused.
To reduce the risk of injury from shock and arc blasts, always wear personal protective
equipment where live conductors are exposed.
WARNING
Never attempt to make measurement if any abnormal conditions, such as broken case and
exposed metal parts are found on the instrument.
Do not rotate the Rotary Dial while the test leads are being connected.
Verify proper operation on a known source before use or taking action as a result of the indication of the instrument.
Do not install substitute parts or make any modifi cation to the instrument. For repair or re-
calibration, return the tool to a factory Service/Sales Support Branch or authorized service
station.
Do not try to replace the batteries if the surface of the instrument is wet.
Disconnect all the cords and cables from the object under test and power off the instrument
before opening the Battery Cover for Battery replacement.
This tool is designed to be powered by 2-AA batteries properly inserted into the MILWAUKEE
Clamp Meters. Do not attempt to use with any other voltage or power supply.
Install battery according to polarity (+ and –) diagrams.
Do not leave batteries within the reach of children.
Do not mix new and used batteries. Do not mix brands (or types within brands) of batteries.
Properly dispose of used batteries.
Do not incinerate or dismantle batteries.
Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact
accidentally occurs, fl ush with water. If liquid contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or burns.

CAUTION
Set the Rotary Dial to an appropriate position before starting measurement.
Firmly insert the test leads.
Disconnect the test leads from the instrument for current measurement.
Do not expose the instrument to the direct sun, high temperature and humidity or dew fall.
Altitude 2000m or less. Appropriate operating temperature is within -10ºC and 50ºC.
This instrument isn’t dust & water proofed. Keep away from dust and water.
Be sure to power off the instrument after use. When the instrument will not be in use for a long
period, place it in storage after removing the batteries.
Use a cloth dipped in water or neutral detergent for cleaning the instrument. Do not use
abrasives or solvents.

2. With the jaws closed and without
clamping them around a conductor, press the ZERO key to zero
adjust the display.
3. Press the jaw opening trigger to
open the jaws and clamp them
around the conductor under test.
The reading is displayed.
NOTE: Do not clamp over 2 or
more wires at the same time.
Irregular results will occur.
4. Set the Rotary Dial to an appropriate position according to current under test.
5. Press the ZERO key again to release the ZERO
function.
CAUTION When current fl ows from
the display side to the underside of
the meter, the polarity is positive; fl ow from
underside to display side, the polarity is
negative.

which voltage over DC600V exists.
Do not use with the Battery Cover removed.
Keep fi ngers away from jaws during mea-
surements.
1. Set the Rotary Dial to position.
2. Connect the red
test lead to the V
terminal and the
black test lead to
the COM terminal.
3. Connect the red
test lead to the
positive (+) side
and black test
leads to the negative (-) side of the
circuit under test.
The reading is displayed. A reversed connection
is indicated as a negative value.
Resistance/Continuity/Capacitance
Measurements
DANGER
To reduce the risk of electric shock for
Resistance, Continuity, and Capacitance
measurements, never use the meter on an
energized circuit. Make sure a capacitor is
fully discharged before touching or attempting to make a measurement.
Do not use with the Battery Cover removed.
Resistance
1. Set the Rotary Dial to
position.
2. Connect the red test
lead to the V terminal and the black

the tips of test leads
to make the indication zero.
3. Connect the test
leads to both ends of the resistor under test.
4. The reading is displayed.
CAUTION
After shorting the test leads, the displayed
value may not be zero due to the resistance
of test leads themselves.
Continuity
1. Set the Rotary Dial to
position.
2. Connect the red test lead
to the V terminal and the
black test lead to the COM
terminal.
Confi rm “OL” is indicated on

Non-Contact Voltage Detection (NCVD)
DANGER
The LED may not be displayed due to installation condition of electrical circuit or equipment. Never touch the circuit under test to
avoid possible danger even if the LED for
NCVD is not displayed.
Check the functionality of LED on a wellknown power supply prior to measurement.
When the LED doesn’t light up, do not make
measurement.
NCVD indication is affected by external voltage, and how the meter is held or placed.
When the meter is on in any
function, the non-contact voltage detector will indicate with a
Red LED on the display when
an electric fi eld exceeding 90V
is detected. Place the edge of
the jaw labeled “Voltage Detector” near the electric fi eld.
CAUTION
When the Rotary Dial is set to , the room
temperature should be displayed. If anything
else is displayed, something may be wrong
with the meter. Stop using the meter immediately.
Worklight LED ON/OFF
To turn the light on and off, press the button.
HOLD Key
Data Hold Function - Freezes the value on the
display. Press the “HOLD” button to freeze the
reading. The reading will be held regardless of
subsequent variation in input. HOLD is displayed
with the reading. To exit Data Hold mode, press the
HOLD button again.
CAUTION
The Data Hold readings are released when the
meter enters Sleep Mode.
Sleep Mode
The clamp meter is automatically powered off in
about 20 min after the last Rotary Dial or button
operation. To reset, rotate the Rotary Dial to OFF.
If the display is still blank when a new Rotary Dial
setting is selected, replace the batteries.
The sleep mode is disabled when the MIN/MAX
function is selected.
The clamp meter does use battery power in sleep
mode. Be sure to switch the tool to OFF to conserve
battery power.
Over-fl ow indication
Any time the input exceeds the
measuring range “OL” or “-OL” is displayed.
CAUTION
Clamp the jaws around the conductor under
test and press the MIN/MAX button after an
appropriate range is selected by Auto-ranging function. ZERO and Hz keys are disabled
while MIN/MAX Function is active.
MIN/MAX Function
The MIN/MAX function can be
used during measurements of AC
or DC current, AC or DC voltage,
Temperature (2236-20 only), uA DC
(2236-20 only), and Resistance.
The MIN/MAX function does not
work in the Capacitance or Continuity measurements.
To measure the minimum or maximum of the function, set the dial to
the appropriate dial position and
then press the MIN/MAX button
to capture the maximum reading.
Press the MIN/MAX button again to
capture the minimum reading.
Press the MIN/MAX button to toggle between
minimum or maximum. The minimum or maximum
reading is displayed and held until the MIN/MAX is
turned off by holding in the MIN/MAX button for 2
seconds or changing the Rotary Dial position.
