To prevent an electrical shock hazard to the operator and/or damage to the
instruments, read this instruction manual carefully before using the Digital
Multimeter. WARNINGS with the symbol on the Digital Multimeter and
this instruction manual are highly important.
Important Symbols
The symbol listed in IEC 61010-1 and ISO 3864 means "Caution
(refer to instruction manual)".
WARNING :
The symbol in this manual advises the user of an
electrical shock hazard that could result in serious injury or even
death.
CAUTION :
The symbol in this manual advises the user of an
electrical shock hazard that could cause injury or material damages.
KU-2600 is designed to comply with CAT
Ⅱ
600V. But, do not measure High
Power Line of more than 3kVA power. High Power Line sometimes includes
High Surge Voltage that could possibly induce dangerous arcs of explosive
short in the instrument and could result in serious injury to the operator. Even
if it is Low Power Line, use extreme care when measuring high voltage.
Thank you for purchasing KAISE "MODEL KU-2600 DIGITAL MULTIMETER".
To obtain the maximum performance of this instrument, read this Instruction
Manual carefully, and take safe measurement.
Inspect the instrument and acessories for transport damage. If any damage or
missing items are found, ask your local dealer for replacement.
Confirm that the following items are contained in the package.

WARNING 4. Dangerous Voltage Measurement Procedure
WARNING 2. Warning for High Power Line Measurements
4-1. WARNINGS
Correct knowledge of electric measurements is essential to avoid unexpected
danger such as operator's injury or damage to the instrument. Read carefully and
observe the following precautions for safety measurements.
Before measurement, confirm the body of this instrument and handle insulators of
the Test Leads have no cracks or any other damages. Dust, grease and moisture
must be removed.
High Power Line (High Energy Circuits) such as Distribution Transformers, Bus
Bars and Large Motors are very dangerous. High Power Line sometimes includes
High Surge Voltage that could cause explosive short in the instrument and could
result in shock hazard. For voltage measurement of High Power Line, do not
touch Clamp Meter, its Test Leads, and any part of the circuit.
Even for Low Energy Circuits of electric/electronic appliances, such as heating
elements, small motors, line cords and plugs, High Voltage Measurements are
very dangerous. Do not touch Clamp Meter, Test Leads, and any part of the
circuit. Generally, shock hazard could occur when the current between the circuit,
that involves more than 33V rms or 46.7V DC or peak, and ground goes up to
0.5mA or more.
For dangerous voltage measurement, strictly observe the following procedure.
Before measurement, turn off the power of the circuit to be measured.
Plug Black Test Lead into COM terminal and Red Test Lead into V
Ω
Hz
terminal.
Attach Black and Red Alligator clips (optional) to Test Lead pins.
Set FUNCTION Switch to
〜
V or V.
Confirm the power of the circuit to be measured is turned off. Connect Black
Alligator Clip to
−
(earth) side and Red Alligator Clip to + (positive) side.
(Refer to fig.2)
Place the Digital Multimeter away from your body not holding it in your hands.
Take safety distance from power source or circuit not to touch the dangerous
voltage.
Turn on the power of the circuit. Read the measurement value on LCD.
After measurement, turn off the power of the circuit and discharge the all
capacitors.
Disconnect Alligator Clips (with Test Leads) from the circuit.

Attach Black Alligator Clip to Black Test Lead pin. Connect it to
−
(earth) side
of the circuit to be measured.
Take safety distance from power source or circuit not to touch the dangerous
voltage.
Hold Red Test Lead with one hand and connect it to
＋
(positive) side. (Refer

Read the measurement value on LCD.
After measurement, disconnect Red Test Lead and Black Alligator Clip from
the circuit.
