WARNING
READ ALL SAFETY WARNINGS AND IN-
STRUCTIONS.
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 Clamp Meters. Before
using, read this operator’s manual and all labels
on the Clamp Meters.
DANGER
Never make measurement on a circuit in which
voltage over AC600V exists. Use only leads rated
600V or better.
Do not attempt to make measurement in the pres-
ence 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 cir-
cuit under test. If equipment under test has exposed
conductive parts, however, extra precaution should
be taken to minimize the possibility of shorting.
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.
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 func-
tions 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 abnor
-
mal 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 modi
-
fication to the instrument. For repair or re-cali
-
bration, 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 batter
-
ies properly inserted into the MILWAUKEE Clamp
Meters. Do not attempt to use with any other volt-
age 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 acciden
-
tally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid eject
-
ed 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 -10ºC and 50ºC.
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.
