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
1
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.

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
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
DANGER
7
Operating Precautions
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.
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.
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.

WARNING
CAUTION
NOTICE
Continued on next page →
IMPORTANT
• 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)
Operating Precautions
• 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.

1.1 Installing the Batteries and Wireless Adapter

When using the instrument for the rst time, install two LR6 Alkaline batteries. (p. 16) In addition, check that there is adequate remaining power in the batteries before starting the measurement.
Appears There is adequate remaining battery power.
Appears When the remaining power decreases, the indicator disappears from the left.
Appears The batteries are exhausted. Replace the batteries as soon as possible.
Blinks The batteries are exhausted. Replace the batteries with new ones.
The CM4003 can be used by connecting an external power supply without installing the batteries. (p. 17)
When the Z3210 Wireless Adapter (option) is installed, the wireless communications function can be used. (p. 42)

Installing the Batteries and Wireless Adapter
Do not short-circuit the battery. Do not charge the battery. Do not disassemble the battery.
Do not throw the battery into a re or heat it up.
Doing so can cause the battery to explode, resulting in bodily injury.
Before removing the battery cover, disconnect the instrument from an
object under measurement and turn o󰀨 the instrument.
When the instrument is clamped around the object under measurement, the battery contacts are regarded as high-voltage parts. Removing the battery cover in this state could cause electric shock.
After replacing the batteries or after installing/removing the Z3210,
install the battery cover and tighten the screws before use.
Secure the battery cover with the screws attached to the instrument at
the time of shipment.
If the battery cover is secured with other screws, the instrument could be damaged, resulting in bodily injury. If you have lost a screw or nd that the screw is damaged, please contact your authorized Hioki distributor or reseller.

WARNING
Installing the Batteries and Wireless Adapter
NOTICE
Do not mix batteries of di󰀨erent ages or types.
Do not use a battery whose recommended service life has expired. Do not reverse the battery polarity. Do not leave the exhausted batteries in the instrument.
Use the specied batteries only (LR6 Alkaline batteries).
Remove the batteries when the instrument is not in use for an extended period
of time.
Failure to do so may cause the battery to leak, damaging the instrument.
Before connecting/disconnecting the Z3210, touch any metallic part, such as a
doorknob, to eliminate static electricity on your body.
Failure to do so may cause static electricity to damage the Z3210.
