1. GENERAL INSTRUCTIONS
This instrument complies with IEC 61010-1：2001, CAT  1000V and CAT Ⅵ600V overvoltage standards. See
Specifications.
To get the best service from this instrument, read carefully this user's manual and respect the detailed safety
precautions.
International symbols used on the Meter and in this manual are explained in chapter 1.2.
1.1 Precautions safety measures
1.1.1 Preliminary
*As the possibilities of high transient overvoltages occurred in today’s power systems increase, more stringent
safety standards are set for the electrical test equipment. Transients on electrical systems(power grid, feeder or
branch circuits) will trigger a series of incidents that may result in serious personal injury. To protect you against
transients, safty must be built into the test equipment.

Overvoltage
cate
g
or
y
In brief Examples
CATⅠElectronic
• Protected electronic equipment.
• Equipment connected to (source) circuits in which measures are taken to
limit transient overvoltages to an appropriately low level.
• Any high-voltage, low-energy source derived from a highwinding
resistance transformer, such as the high-voltage section of a copier.
CATⅡ
Single-phase
receptacle
connected loads
• Appliance, portable tools, and other household and similar loads.
• Outlet and long branch circuits.
• Outlets at more than 10 meters (30 feet) from CAT III source.
• Outlets at more that 20 meters (60 feet) from CAT IV source.
CAT Ⅲ
Three-phase
distribution,
including
single-phase
commercial lighting
• Equipment in fixed installations, such as switchgear and polyphase
motors.
• Bus and feeder in industrial plants.
• Feeders and short branch circuits, distribution panel devices.
• Lighting systems in larger buildings.
• Appliance outlets with short connections to service entrance.
CAT Ⅵ
Three-phase at
utility connection,
any outdoor
conductors
• Refers to the “origin of installation”; i.e., where low-voltage connection is
made to utility power.
• Electricity meters, primary overcurrent protection equipment.
• Outside and service entrance, service drop from pole to building, run
between meter and panel.
• Overhead line to detached building, underground line to well pump.
*When using this Multimeter, the user must observe all normal safety rules concerning:
―protection against the dangers of electric current.
―protection of the Multimeter against misuse.
*For your own safety, only use the test probes supplied with the instrument. Before use, check that they are in good
condition.

1.1.2 During use
*If the meter is used near noise generating equipment, be aware that display may become unstable or indicate large
errors.
*Do not use the meter or test leads if they look damaged.
*Use the meter only as specified in this manual; otherwise, the protection provided by the meter may be impaired.
*Use extreme caution when working around bare conductors or bus bars.
*Do not operate the meter around explosive gas, vapor, or dust.
*Verify a Meter's operation by measuring a known voltage. Do not use the Meter if it operates abnormally. Protection
may be impaired. When in doubt, have the Meter serviced.
*Uses the proper terminals, function, and range for your measurements.
*When the range of the value to be measured is unknown, check that the range initially set on the multimeter is the
highest possible or, wherever possible, choose the autoranging mode.
*To avoid damages to the instrument, do not exceed the maximum limits of the input values shown in the technical
specification tables.
*When the multimeter is linked to measurement circuits, do not touch unused terminals.
*Caution when working with voltages above 60Vdc or 30Vac rms. Such voltages pose a shock hazard.
*When using the probes, keep your fingers behind the finger guards.
*When making connections, connect the common test lead before connecting the live test lead; when disconnecting,
disconnect the live test lead before disconnecting the common test lead.
*Before changing functions, disconnect the test leads from the circuit under test.
*For all dc functions, including manual or auto-ranging, to avoid the risk of shock due to possible improper reading,
verify the presence of any ac voltages by first using the ac function. Then select a dc voltage range equal to or
greater than the ac range.
*Disconnect circuits power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or
capacitance.
*Never perform resistance or continuity measurements on live circuits.
*Before measuring current, check the meter's fuse and turn off power to the circuit before connecting the meter to
the circuit.
