INSTRUCTION MANUAL
KU-2600
FOR SAFETY MEASUREMENTS!!
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.
WARNING
KU-2600 is designed to comply with CAT ‡U 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.

Select or , and DC or AC.
4. RANGE Key
When making voltage, resistance or mA measurements, press RANGE Key to
select Range Hold. AUTO symbol turns off from LCD. There are two ways in
Range Hold.
1. Just press RANGE Key several times to select a desired range watching the
position of decimal point. The decimal point moves from the lowest range to
the highest range and circulates with each press.

4. SAFETY PRECAUTIONS
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.
4-1. WARNINGS
WARNING 1. Checks of Body and Test Lead
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.
WARNING 2. Warning for High Power Line Measurements
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.
WARNING 3. Warning for High Voltage Measurements
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,
fig.1
that involves more than 33V rms or 46.7V DC or peak, and ground goes up to
0.5mA or more.
WARNING 4. Dangerous Voltage Measurement Procedure
For dangerous voltage measurement, strictly observe the following procedure.
1. Before measurement, turn off the power of the circuit to be measured.
2. Plug Black Test Lead into COM terminal and Red Test Lead into VĦHz
terminal.
3. Attach Black and Red Alligator clips (optional) to Test Lead pins.
4. Set FUNCTION Switch to •`V or V.
Confirm the power of the circuit to be measured is turned off. Connect Black
5.
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.
6.
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.
7.
8. After measurement, turn off the power of the circuit and discharge the all
capacitors.
Disconnect Alligator Clips (with Test Leads) from the circuit.
9.
In case of live-line measurement, observe the following procedure.
1. Place the Digital Multimeter away from your body not holding it in your hands.
2. Set FUNCTION Switch to •`V or V.
3. Attach Black Alligator Clip to Black Test Lead pin. Connect it to •| (earth) side
of the circuit to be measured.
4. Take safety distance from power source or circuit not to touch the dangerous
voltage.
5. Hold Red Test Lead with one hand and connect it to •{ (positive) side. (Refer
to fig. 3)
6. Read the measurement value on LCD.
7. After measurement, disconnect Red Test Lead and Black Alligator Clip from
the circuit.
WARNING 5. Maximum Input Observance
Do not attempt to measure voltage that might exceed 600V AC or DC, the
specified maximum input of this instrument.
