Regarding Safe Use of This Product
This product is designed to be used by a person with specialized
knowledge. The general safety precautions described herein must
be observed during all phases of operation.
If the instrument is used in a manner not specified in this manual,
the protection provided by the instrument may be impaired.
This manual is part of the product and contains important information.
Store this manual in a safe place close to the instrument so that
you can refer to it immediately.
Keep this manual until you dispose of the instrument.
YOKOGAWA assumes no liability for the customer’s failure to
comply with these requirements.
The following safety symbols are used on the instrument
and in this manual.
WARNING
Indicates a hazard that may result in the loss of life or serious
injury of the user unless the described instruction is abided by.
CAUTION
Indicates a hazard that may result in an injury to the user and/or
physical damage to the product or other equipment unless
the described instruction is abided by.
Danger! Handle with Care.
This mark indicates that operator must refer to an explanation
in the instruction manual in order to avoid risk of injury
or death of personnel or damage to the instrument.
This symbol indicates that this instrument designed to be
applied around or removed from HAZARDOUS LIVE
conductors provided if the RATED circuit-to-earth voltage
does not exceed the value indicated in the measurement
category.
This symbol indicates AC voltage/current.
This symbol indicates double insulation.
Strictly observe the following cautionary notes in order to
avoid the risk of injury or death of personnel or damage
to the instrument due to hazards such as electrical shock.
WARNING
• This instrument is for measuring AC current (clamping sensor).
Do not use this instrument for other purpose.
• Do not use the instrument if there is a problem with its physical
appearance.
• To avoid a short-circuit or an accident to personnel,
use this product within the RATED circuit-to-earth voltage of
measurement category.
• Do not use the product when there are raindrops or droplets of
condensed water on its surface, or if your hands are wet.
• Barrier is for to avoid touching the HAZARDOUS LIVE
conductor.
Be careful not to across the Barrier when using the instrument.
• Safety protectors such as rubber-insulated gloves should be
worn to prevent electrical shock when using the instrument.
• Do not use this product in a place where an explosive gas or
vapor is present.
• Do not use the instrument if there is any damage to the casing or
when the casing is removed. Do not attempt to repair/modify
the product yourself, as doing so is extremely dangerous.
Should an abnormality or failure in the product be found,
contact the vendor from which you purchased the product.
CAUTION
• The use of this instrument is limited to residential, commercial,
and light-industrial environments. This instrument may not be
able to measure accurately if it is near other equipment
generating strong electromagnetic interference or a strong
magnetic field caused by large current.
• Do not use the instrument in areas subject to rapid temperature
fluctuations.
• The clamping JAWS are precision assembled to ensure high
performance. When using the clamp, do not apply intense
mechanical shock, vibration, or force to the clamping JAWS.
• If dust or any other foreign matter gets in the clamping JAWS,
do not close the clamping cores tight. First remove the dust
and then make sure the clamping cores on both sides close
smoothly.
Cleaning
To remove dirt, disconnect the lead plugs and gently wipe the outer
surface with a clean and soft cloth.
Do not use a chemical agent such as benzine or paint thinner.
Measurement Category
WARNING
The probe is designed for measurement category II.
(The RATED circuit-to-earth voltage: 600 Vrms)
Do not use the probes for measurements in locations falling under
Measurement Categories III, and IV.
The probes are designed for measurement category III.
(The RATED circuit-to-earth voltage: 300 Vrms)
Do not use the probes for measurements in location falling under
Measurement Category IV.

Measuring Method
To avoid damage to instrument
CAUTION
Do not apply a current exceeding the maximum allowable
current, as this may cause damage to the instrument.
1. Turn the digital multimeter's power on and then set the function
switch to [AC V].
2. Connect the lead plugs from the clamp probe to the digital
multimeter input terminals. In this case, connect the red plug
to terminal [V], the black plug to terminal [com].
3. Squeeze on the Open/Close lever to open the clamping JAWS
and clamp one of the wires to be measured.
Make sure that the end of the clamp is closed securely.
4. Read the indication value of the digital multimeter.
< The current value calculation>
Current (I)= =15.00 A
Example When the output voltage is 150.0 mV:
10
150.0
For Precise Measurements
• Clamp only one wire. Clamping a tough rubber-sheathed cable
and a parallel PVC-cable together disables measurement.
• When performing a measurement, hold the probe so that
the measured conductor cable runs at the center of the clamp.
• Ensure that the orientation of the clamp to the direction of
the conductor cable (power source
load) is correct as
shown below, when voltage and current phase related
measurement. The output waveform will thus be positive and
the current phase can be correctly measured.
• Do not connect to the output terminals a resistive load
less than 100 kΩ or a capacitive load over 100 pF.
Otherwise, an error may result.
• Ensure that the clamping JAWS are properly closed.
