Introduction
Introduction
Thank you for choosing the Hioki CM4002/CM4003 AC Leakage Clamp Meter. To ensure your
ability to get the most out of this instrument over the long term, please read this manual carefully
and keep it available for future reference.
Carefully read the separate document entitled “Operating Precautions” before use.
Intended audience
This manual has been written for use by individuals who use the product or provide information
about how to use the product. In explaining how to use the product, it assumes electrical
knowledge (equivalent of the knowledge possessed by a graduate of an electrical program at a
technical high school).

Introduction
Overview
This AC leakage clamp meter allows you to measure from minute leakage current to load current.
Accurately measuring minute leakage current
• The 6.000 mA range is incorporated to ensure the measurement with a high resolution of 1 µA.
• High permeability magnetic material is used for the jaws.
E󰀨ects of external electromagnetic noise are minimized to enable the measurement with high
reproducibility.
Measuring a wide range of current from leakage current to load current
• Accuracy ranging from 0.060 mA to 200.0 A is ensured.
• Frequency band ranging from 15 Hz to 2 kHz.
Principle of leakage current measurement
The instrument is designed based on the principle of electromagnetic induction. The magnetic eld
corresponding to the current owing through the conductor to be measured is detected by a current
transformer that consists of a magnetic core and coil. The current transformer generates the current
corresponding to the magnetic eld. The detection resistor converts this current into the voltage to calculate
the value of the current owing through the conductor.

Notations
Symbols shown on the instrument
Indicates the need for caution or the presence of danger. For more information about
locations where this symbol appears on instrument components, see the “Operating
Precautions” (p. 7), warning messages listed at the beginning of operating instructions, and
accompanying the document entitled “Operating Precautions”.
Indicates AC (Alternating Current).
Indicates that the instrument may be connected to or disconnected from a live conductor.
Indicates an instrument that has been protected throughout by double insulation or reinforced
insulation.
Indicates that using the instrument in an external magnetic eld of exceeding 30 A/m is
prohibited.
Symbols for various standards

Accuracy
Hioki expresses accuracy as error limit values specied in terms of percentages of reading and of full scale.
Reading
(Displayed value)
Refers to the displayed value of the measuring instrument. The limit values of reading
errors are expressed in percent of reading (% of reading, % rdg).
Full scale
(Maximum
displayable value)
Refers to the maximum displayable value of each measurement range. The
instrument has measurement ranges whose values are equal to the maximum
displayable values. The limit values of full-scale errors are expressed in percent of full
scale (% of full scale, % f.s.).

Operating Precautions
Operating Precautions
Be sure to follow the precautions listed below in order to use the instrument safely and in a
manner that allows it to function e󰀨ectively. Please review the separate “Operating Precautions”
before using the instrument. Use of the instrument should conform not only to its specications,
but also to the specications of all accessories, options, and other equipment in use.
Handling the instrument
DANGER
Do not use the instrument outside its rated range or specications.
Doing so could cause damage to the instrument or overheating, resulting in serious
bodily injury.
Do not measure any current in excess of the derating curve.
Doing so can cause overheating of the sensor, resulting in bodily injury, re, or
damage to the instrument.
See “Frequency derating characteristics” (p. 51).
The maximum measurement current varies with the frequency, and the current that
can be measured continuously is limited. Operating the instrument at less than this
limitation is referred to as derating.

Operating Precautions
WARNING
Do not approach any high voltage equipment or wiring when
measuring with a ground wire for class B grounding work of the
transformer.
Otherwise, the user may receive electric shock.
When the ground wire is close to a high voltage live part, change the
route of the grounding wire.
CAUTION
Do not bend or pull on cables at temperatures of 0°C or lower.
Since cables become rigid, doing so could damage the insulation or cause a wire
break, resulting in electric shock.
NOTICE
Keep the jaws closed when the instrument is not in use.
Leaving the jaws open will cause dust or dirt to settle on the facing core surfaces,
resulting in damage to the instrument.

Operating Precautions
IMPORTANT
• Do not allow any foreign object to be caught between the facing core surfaces of
the jaws.
• Do not scratch the facing core surfaces of the jaws.
• Do not touch the facing core surfaces of the jaws with your ngers.
• Do not insert any foreign object into the gap of the jaws.
• Do not drop the instrument.
• Do not subject the instrument to any shock.
Doing so may adversely a󰀨ect the measurement accuracy and open/close operation.
• Electric circuit on which DC components are superimposed may not be measured accurately.
• Displayed values can frequently uctuate due to induction potential even when no voltage is
applied. This, however, is not a malfunction.
• When the mark blinks, the batteries are exhausted. Replace the batteries as soon as
possible. (p. 16)
