1. SAFETY INFORMATION
This Instruction Manual provides information and warnings essential for operating
this meter in a safe manner and for maintaining it in safe operating condition. Before
using this meter, be sure to carefully read the following safety information.
DANGER
•During high voltage measurement, incorrect measurement procedures could
result in injury or death, as well as damage to the meter. Please read this
manual carefully and be sure that you understand its contents before using the
meter.
DANGER
•Do not use the meter or test leads if they look damaged.
•Use extreme caution when working around bare conductors or bus bars,
Accidental contact with the conductor could result in electric shock.
•To avoid damages to the meter, do not exceed the maximum limits of the input
values shown in the specifications.
•Use the meter only as specified in this manual, otherwise, the protection
provided by the meter may be impaired.
SAFETY SYMBOLS
•Caution refer to this manual before using the meter.
•
This symbol is affixed to the meter where the operator should consult
corresponding topics before using relevant functions of the meter.
•
This mark indicates explanation, which is particularly important that the
user should read before using the meter.
Dangerous voltages.
Meter is protected throughout by double insulation or reinforced insulation.
When servicing, use only specified replacement parts.
Comply with IEC61010-1, 2nd edition

DANGER: Indicates that incorrect operation presents extreme danger of
accident resulting in death or serious injury to the user.
WARNING: Indicates that incorrect operation presents significant danger of
accident resulting in death or serious injury to the user.
CAUTION: Indicates that incorrect operation presents possibility of injury to
the user or damage to the meter.
NOTE: Denotes items of advice related to performance of the meter or to its
correct operation.
NOTES ON USE
In order to ensure safe operation and to obtain maximum performance from the
meter, observe the caution listed below.
Installation
CAUTION
•The meter is designed for indoor use and can be safely used at temperatures
ranging from 0℃to 40℃.
•Do not store or use the meter where it will be exposed to direct sunlight, high
temperature, high humidity, or condensation, if exposed to such conditions, the
meter may be damaged, the insulation may deteriorate, and the meter may no
longer satisfy its specifications.
•The meter does not construct to be waterproof or dustproof, so do not use it in
a very dusty environment or in one where will get wet.
•Do not use the unit where it may be exposed to corrosive or explosive gas. The
meter may be damaged, or may occur explosion.
Before use
WARNING
•To prevent electric shock, do not allow the meter to become wet and do not use
the unit when your hands are wet.
•When working with live circuits, take all suitable precautions against
accidents, including the use of electrical safety gear such as rubber gloves,
rubber boots, and safety helmets.

Connecting meter
WARNING
•To prevent electric shock, turn the power off before connecting the test leads
and then take measurements.
•In order to prevent electrical shock and short – circuit accidents, shut off the
power to the line to be measured before connecting the line to be measured to
the voltage input terminals.
CAUTION
•The measurement input and synchronizing input are not isolated from each
other. Connecting either one means that the other is exposed it is live, and
there is a danger of electric shock. To avoid electrical shock, connect both
terminals.
WARNING
To avoid electrical shock and / or meter damage, use caution when connecting
test leads to live components. The jaws of alligator clips can create a short
circuit between closely spaced live parts. Avoid making connections to feeder
conductors or bus bars at elevated potentials. Whenever, please make
connections to the output side of a circuit breaker as possible as you can, which
can provide better short circuit protection.
•Follow all legal requirements.
•Follow all instructions in the manuals.
•Obey posted instructions.
•Never assume that a circuit is de-energized, check it first.
•Always set up the measurement first, then connect the test leads to the circuit.
•Remove all test leads that are not in use.
•Make connections to the meter first, before connecting leads to a live circuit.
•Connect the ground lead first, then the voltage leads and the current probe,
Disconnect in reverse order.
•Route test leads carefully.

5. OPERATING INSTRUCTION
CAUTION
•If possible, before connecting the meter to the electrical equipment to be
tested, take off the electrical equipment’s power.
DANGER
•Voltage input connectors U1 to U3 are common for input connector N, each
input connectors are not insulated.
•Do not connect the unnecessary number of cords.
WARNING
•Always set up the measurement first, then connect the test leads to the circuit.
•Make connections to the instrument first, before connecting leads to a live
circuit.
•Connect the ground lead first, then the voltage leads and the current probe,
Disconnect in reverse order.
•Remove all test leads that are not in use.
※U1 must be connected to voltage source during the measurement of U2, U3,
I1, I2 and I3, because U1 is the main signal source of the whole meter
measuring system. Otherwise you could not have any measurement from
U2, U3, I1, I2 and I3.

Safety Information
Read First: Safety Information
To ensure safe operation and service of the current clamp, follow these instructions:
•Read the operating instructions before use and follow all safety instructions.
•Use the Current Clamp only as specified in the operating instructions,
otherwise the clamp’s safety features may not protect you.
•Adhere to local and national safety codes. Individual protective equipment
must be used to prevent shock and arc blast injury where hazardous live
conductors are exposed.
•Do not hold the Current Clamp anywhere beyond the tactile barrier, see Figure 1.
