Nearly every electrical engineer has a hand held
Multimeter. We sometimes take them for granted, until we
damage them or “burn them out”. If you incorrectly
connect your DMM to a circuit or have the DMM on wrong
setting, you damage the meter and possibly hurt yourself.
You can also get into trouble if you try to measure the
voltage across a charged capacitor.
DMM users frequently burn their meters by trying to
measure current the same way as they measure voltage,
Remember, you measure voltage across a circuit, and
current through a circuit. When you use the current input,
your DMM becomes a low impedance circuit element. If
you accidentally connect this low impedance path across
your circuit, you’ll effectively short-circuit it. You can,
therefore send high current through your meter and
severely damage it. Unless the meter has a fused input,
you can even get an explosion or fire.
Even if you correctly insert your DMM into the circuit, you
can still damage your meter. Don’t try to measure current
in excess of your meter’s capacity. Handheld DMMs
usually have a maximum current rating of 10Aor 20A.
If you are measuring current in industrial environment, you
can easily exceed those ratings. The best way to avoid
damage is to use a clamp meter or to connect a clamp
attachment to your DMM.
To prevent excess current from flowing through your
meter, always disconnect the test leads from the circuit
under test whenever you change DMM functions, Set your
meter to the correct function, say current and its highest
range for the setting, say 20A.
Next, connect the test leads before you apply power to the
circuit. To be safe, start by setting your meter to its highest
range first.
TAKE MEASUREMENT CAREFULLY AND YOU’LL
SPARE YOUR METER AND YOURSELF, SOME PAIN

1. SAFETY INFORMATION
KUSAM-MECO April 2011
®
This manual contains information and warnings
that must be followed for operating the instrument
safely and maintaining the instrument in a safe
operating condition. If the instrument is used in a
manner not specified by the manufacturer, the
protection provided by the instrument may be
impaired. The meter is intended only for indoor
use.
The meter protection rating, against the users, is
double insulation per IEC61010-1 2nd Ed.,
EN61010-1 2nd Ed., UL61010-1 2nd Ed., & CAN/
CSA C22.2 No. 61010.1-0.92,to Category II
1000 Volts, CAT III 600 Volts & CAT IV 300 Volts
AC & DC.
Terms In This Manual
WARNING Identifies conditions & actions that could
result in serious injury or even death to
the user.
CAUTION Identifies conditions & actions that could
cause damage or malfunction in the
instrument.
Terminals (to COM) measurement category:
V : Category II 1000V, Category III 600V
and Category IV 300V AC & DC.
A /mAµA : Category III 600 Volts AC and
300 Volts DC.

Per IEC61010-1 2nd Ed. (2001) Measurement
Category
Measurement Category IV (CAT IV) is for
measurements performed at the source of the low-
voltage installation. Examples are electricity
meters and measurements on primary overcurrent
protection devices and ripple control units.
Measurement Category III (CAT III) is for measure-
ments performed in the building installation.
Examples are measurements on distribution boards,
circuit-breakers, wiring, including cables, bus-bars,
junction boxes, switches socket-outlets in the fixed
installation, & equipment for industrial use & some
other equipment, for example, stationary motors
with permanent connection to the fixed installation.
Measurement Category II (CAT II) is for measure-
ments performed on circuits directly connected to the
low voltage installation. Examples are measure-
ments on household appliances, portable tools &
similar equipment.
WARNING
To reduce the risk of fire or electric shock, do not
expose this product to rain or moisture. To avoid
electrical shock hazard, observe the proper safety
precautions when working with voltages above
60 VDC or 30 VAC rms. These voltage levels pose a
potential shock hazard to the user. Do not touch test
lead tips or the circuit being tested while power is
applied to the circuit being measured. Keep your
fingers behind the finger guards of the test leads

Disconnect the test leads from the test points
before changing functions. Always set the
instrument to the highest range and work down-
ward for an unknown value when using manual
ranging mode.
CAUTION
during measurement. Inspect test leads,
connectors, and probes for damaged insulation or
exposed metal before using the instrument. If any
defects are found, replace them immediately. Do
not measure any current that exceeds the current
rating of the protection fuse(s). Do not attempt a
current measurement to any circuit where the
open circuit voltage is above the protection fuse(s)
voltage rating(s). Suspected open circuit voltage
should be checked with voltage functions. Never
attempt a voltage measurement with the test lead
inserted in to the µA/mA or A input jack. Only
replace the blown fuse(s) with the proper rating
as specified in this manual. Only use the lead
provided with the equipment or UL Listed Probe
Assembly.
The instruments conform to CENELEC Low-
Voltage directive 2006/95/EC and Electromagnetic
compatibility directive 2004/108/EC
