IMPORTANT
SAFETY
INSTRUCTIONS
READ ALL SAFETY WARN-
WARNING
INGS 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 dam-
age to the equipment being tested.
Save these instructions - This operator's manual
contains important safety and operating instruc-
tions for the MILWAUKEE True RMS Multimeters
(DMM). Before using, read this operator's manual
and all labels on the True RMS Multimeters.
DANGER
Never make measurement on a circuit in which
voltage over 600V rms exists. Use only leads
rated 600V CAT III or better.
Do not apply more than the rated voltage, as
marked on the DMM, between terminals or be-
tween any terminal and earth ground.
Do not attempt a current measurement when the
open voltage is above the fuse protection rating.
Suspected open circuit voltage can be checked
with voltage function.
Do not use the DMM to measure voltages in cir-
cuits that could be damaged by the DMM's low
input impedance in Lo-Z Function. Impedance
is approximately 4KΩ.
Do not attempt to make measurement in the pres-
ence 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 abso-
lutely necessary.
Check tool functionality on a known circuit first.
Never assume tool is working. Assume circuits
are live until they can be proven de-energized.
Never open the Battery cover during a measure-
ment.
Do not ground yourself while measuring. Avoid
body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigera-
tors.
This instrument is to be used only in its in-
tended 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 equip-
ment 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.
Comply with local and national safety require-
ments when working in hazardous locations.
Keep fingers behind the guards and away from
test lead tips during measurements.
Do not rotate the Rotary Dial while the test leads
are being connected.
Never attempt a voltage measurement with the
test lead inserted into the A input terminal.
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, replace fuse or
make any modification to the instrument. For
repair or re-calibration, return the tool to a fac-
tory 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
True RMS Multimeters. 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 Rotary Dial to an appropriate position
before starting measurement.
Disconnect test leads from test points before
changing Rotary Dial functions.
Never connect to a source of voltage with the
Dial function in OFF/Ω/ / / /
Firmly insert the test leads.
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.
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 damp cloth or neutral detergent for cleaning
the instrument. Do not use abrasives or solvents.
