IMPORTANT SAFETY INSTRUCTIONS
Symbology
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 Fork Meters. Before using, read this operator’s manual and
all labels on the Fork Meters.
DANGER
Never make measurement on a circuit in which voltage over AC1000V exists. Use only leads
rated 1000V or better.
Do not attempt to make measurement in the presence of fl ammable gases. Otherwise, the use
of the instrument may cause sparking, which can lead to an explosion.
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 sur-
faces such as pipes, radiators, ranges and refrigerators.
Never open the Battery cover during a measurement.
This instrument is to be used only in its intended applications or conditions. Otherwise, the
instrument's safety functions may not work, resulting in serious personal injury and instru-
ment damage.
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 indi-
cation 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
Fork 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 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 dewfall.
Altitude 2000m or less. Appropriate operating temperature is within -10ºC and 50ºC.
Keep away from excess 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.
