Safety Information

• 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 IEC 61010-1 2nd Ed., EN 61010-1 2nd Ed., Category III 1000 Volts
AC & DC and Category IV 600 Volts AC & DC.

• Disconnect the test leads from the test points before changing the

position of the function rotary switch.

• Never connect a source of voltage with the function rotary switch in

, , , μA, position.

• Do not expose Meter to extremes in temperature or high humidity.

• Never set the meter in

of a power supply circuit in equipment that could result in damage
the meter and the equipment under test.

Measurement category:
V : Category III 1000 Volts AC & DC, and Category IV 600 Volts AC & DC.
A : Category III 1000 Volts AC & DC, and Category IV 600 Volts AC & DC.

Per IEC 61010-1 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 measurements 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, and equipment for
industrial use and some other equipment, for example, stationary motors
with permanent connection to the fixed installation.

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 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. Only use
the accompanied test leads, or replace with the same rating or better.

Making Basic Measurements

CAUTION

Before and after hazardous voltage measurements, test the voltage
function on a known source such as line voltage to determine proper meter
functioning.

When connecting the test leads to the EUT (Equipment Under Test) connect
the common test lead before connecting the live lead; when removing the
test leads, remove the test live lead before removing the common test lead.

WARNING

To avoid electrical shock, hazard or damage to meter, do not attempt to
measurement that might exceed 1000 V DC or AC RMS. Do not apply more
than 1000 V DC or AC RMS to the input terminals.

Note - If the measured voltage is higher than 30 V DC or AC RMS, the
display will show “
