IMPORTANT SAFETY INSTRUCTIONS
Symbology
WARNING READ ALL SAFETY WARNINGS AND 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 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 flammable 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.
Checktoolfunctionalityonaknowncircuitfirst.Neverassumetoolisworking.Assumecircuits
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 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 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, flush 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.

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 attempt-
ing to make a measurement.
Do not use with the Battery Cover removed.
CAUTION
After shorting the test leads, the displayed
value may not be zero due to the resistance
of test leads themselves.
WARNING
Never connect the Temperature Probe to an
energized circuit.
CAUTION
When the dial is set to , the room tempera-
ture should be displayed. If anything else is
displayed, something may wrong with the
meter. Stop using the meter immediately.

Non-Contact Voltage Detection (NCVD)
Sleep Mode
The meter is automatically powered off in about 20
min after the last Rotary Dial or button operation.
To reset, turn the Rotary Dial to OFF. If the display
is still blank when a new Rotary Dial setting is
selected, replace the batteries.
The meter does use battery power in sleep mode.
Be sure to switch the tool to OFF to conserve bat-
tery power.
ACCESSORIES
WARNING Always remove batteries
before changingor removing accessories.Only
useaccessories specifically recommendedfor
this tool. Others may be hazardous.
DANGER
The LED may not be displayed due to instal-
lation condition of electrical circuit or equip-
ment. 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 well-
known power supply prior to measurement.
When the LED doesn’t light up, do not make
measurement.
NCVD indication is affected by external volt-
age, and how the meter is held or placed.
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
withthereading.To exit DataHoldmode,press the
HOLD button again.
SMART HOLD: The meter will beep continuously
andthedisplaywillflash ifthemeasuredsignalis 50
counts larger than the display reading. (However,
it can not detect across the AC and DC Voltage/
Current)
When the meter is on in any
function, the non-contact volt-
agedetectorwill indicatewitha
Red LED on the display when
anelectricfieldexceeding 90V
is detected. Place the edge of
either the jaw near the electric
field.

To turn the light on and off, press the button.
Over-flow indication
Any time the input exceeds the measuring range
“OL” or “-OL” is displayed.
1.SettheRotaryDial to posi-
tion.
2.Connect the K-type Tem-
perature Probe to the input
terminal. The positive (+)
side of Probe should be
connected to V.
3.Place the probe sensor in
