IMPORTANT SAFETY INSTRUCTIONS
WARNING READ ALL SAFETY WARNINGS AND ALL 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 400 Amp Clamp Meter. Before using, read this operator’s
manual and all labels on the Clamp Meter.
DANGER
Never make measurement on a circuit in which voltage over 600 volts AC 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.
Do not hold the meter above hand-stop.
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 use test leads 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-AAA batteries properly inserted into the MILWAUKEE
Clamp Meter. 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 14°F and 122°F (-10°C
and 50°C).
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.

Making a Measurement
AC Current
DANGER To avoid electrical shock:
Never make measurement on a circuit in
which voltage over 600 volts AC exists. Clamp
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.
Do not use with the battery cover removed.
Disconnect the test leads from the instrument
for current measurement.
1. Set the rotary dial to
position. AC mark is displayed.
2. 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.
200A
CAUTION Maximum conductor size
is 1" diameter. During measurement,
keep the jaws fully closed to ensure accurate
measurements.
AC Voltage
DANGER To avoid electrical shock:
Never make measurement on a circuit in
which voltage over 600 volts AC 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 test leads to
the circuit under test. The
reading is displayed.
DC Voltage
DANGER To avoid electrical shock:
Never make measurement on a circuit in
which voltage over 600 volts DC 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.

Resistance/Continuity Measurements
DANGER
To reduce the risk of electric shock for
Resistance and Continuity measurements,
never use the meter on an energized circuit.
If testing a capacitor, make sure it 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 test lead to the COM
terminal.
Confi rm “OL” is indicated on
the display, and then touch
the tips of the test leads together to short circuit them
to confi rm the zero indication.
3. Connect the test leads to
both ends of the resistor
under test. 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
the display, and then touch
the tips of the test leads together to short circuit them
to confi rm the zero indica-
tion. A buzzer will sound.
3. Connect the test leads to
both ends of the conductor under test. If the
resistance under test is 30 or less, the buzzer
will sound.

Display Backlight
When working in dark environments, use the
display backlight. To turn the backlight on and off,
press the button.
HOLD Button
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 Hold mode, press the HOLD button again.
CAUTION
The Hold readings are released when the
meter enters Sleep Mode.
Sleep Mode
The Clamp Meter is automatically powered off
about 20 minutes after the last rotary dial or button
operation. To reset, turn the rotary dial or press
any button.
The Clamp Meter uses 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.
MAINTENANCE
WARNING To reduce the risk of injury ,
always remove the batteries from the tool
before performing any maintenance. Never
disassemble the tool. Contact a MILWAUKEE
service facility for ALL repairs.
Maintaining Tool
Keep your tool in good repair by adopting a regular
maintenance program. After one year, it is recommended to return the tool to a MILWAUKEE service
facility for calibration.
If the tool does not start or operate at full power
with fully charged batteries, clean the contacts
on the battery door. If the tool still does not work
properly, return the tool to a MILWAUKEE service
facility for repair.
WARNING To reduce the risk of per-
sonal injury and damage, never immerse
