IMPORTANT SAFETY INSTRUCTIONS
WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS.
Failure to follow the warnings and instructions may result in electric shock, fire 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 flammable 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
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 first. Never assume tool is working. Assume circuits are live until they can be proven
Do not ground yourself while measuring. Avoid body contact with earthed or grounded sur- faces 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
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
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.

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 in- dication of the instrument.
Do not install substitute parts or make any modification 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
