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

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.

Measuring Leakage Current
IMPORTANT
In the following cases, the accurate measurement may not be performed.
• A large current (approx. 100 A) ows through adjacent wires.
• A special waveform such as the secondary side of an inverter is measured.
• The jaws are not closed completely.
In particular, if the external dimension of the object under measurement is large, such as when three­phase wires are clamped together in a bundle, make sure that the jaws are closed completely. If the jaws are even slightly open, errors occur in the measured value and the accuracy cannot be ensured.
• The leakage current measurement at zero phase is a󰀨ected by the load current. For the degree of
inuence of the load current, see E12 on p. 60.
22
The RMS value (RMS) and frequency of the leakage current will
appear on the display panel.

Locating an insulation failure

By measuring leakage current of the entire circuit using the ground wire of the transformer (location 1 in the gure on the next page), you can determine the presence or absence of an earth leakage in accordance with changes in leakage current.
When you nd an earth leakage, perform the bundled measurement of all the wires from the
power supply side toward the load side to locate an insulation failure.
To investigate an intermittent earth leakage, the following functions are convenient.
1. Event recording function (p. 45) When the measured value exceeds the set threshold value, the event data (event occurrence time, event stop time, and maximum value) can be recorded. To use this function, the Z3210 (option) and GENNECT Cross (free application software) are
needed.
2. Output function (CM4003 only)
You can record the output value with a recorder. (p. 34)

Precautions for measuring the load current

IMPORTANT
Be sure to clamp the instrument around only one wire of the conductor. Regardless
of the single-phase and three-phase, when clamping around two or more wires
together in a bundle, the load current cannot be measured.

OK
• A special waveform such as the secondary side of the inverter may not be measured.
• In accordance with the magnitude of the input current, a sound may be generated from the jaws
due to resonance, but it does not a󰀨ect the measurement.
• When the magnitude of the input current is unknown, disable the lter function and start the
measurement using the auto-range or 200.0 A range.

Filter Function (FILTER)
Frequency (Hz)

2.2 Filter Function (FILTER)

When a switching power supply or an inverter is connected to the same system as the object
under measurement, high frequency components may be superimposed on the leakage current waveform. Unnecessary high frequency components can be eliminated using the lter function.
Enable the lter function.
1 s
When the lter function is enabled, the frequency band is limited to approx. 180 Hz (−3 dB), which
is equivalent to the frequency band of the general earth leakage circuit breaker.
To analyze the operation of the earth leakage circuit breaker, it is recommended that you use the lter function.

Output Function (OUTPUT) (CM4003 only)

2.8 Output Function (OUTPUT) (CM4003 only)

The voltage corresponding to the measured value is output. (Procedure: p. 36)
RMS (RMS value output)
WAVE (Waveform output)
Use an external power supply to record the measured value for an extended period of time.
(p. 17)
• When using the scaling function of a recorder (such as Hioki’s Memory HiCorder), the voltage
value can be converted into the current value on the recorder.
• For the investigation of the intermittent earth leakage (occasional earth leakage), the RMS
output is recorded with the recorder to check the time variation of the leakage current value.
34
Outputs the DC voltage proportional to the RMS value of the measured current. Recording the voltage with a recorder (such as Hioki’s Memory HiCoder) allows you to check changes in measured current value visually.
Outputs the AC voltage proportional to the measured current. Observing the
voltage with a recorder (such as Hioki’s Memory HiCoder, etc.) allows you to check
the current waveform visually.

Wireless communications Function

2.12 Wireless communications Function

Using the GENNECT Cross

he wireless communications function allows you to check and record the measured data of the
T
instrument, and create the measurement report using your mobile communications device. For details, see the operation guide for the GENNECT Cross app (free of charge).
• The communication distance is about 10 m with a clear line of sight. The communicable distance may vary greatly depending on the presence of an obstruction (wall or metallic shielding object) and the distance between the oor (ground) and instrument. To ensure the stable communication, make sure that the radio wave intensity is su󰀩cient.
• The GENNECT Cross is free of charge. However, the customer is responsible for the cost to download the application software and connect to the Internet when using the software.
• The GENNECT Cross may not operate properly depending on the mobile communications device.
• The Z3210 uses the 2.4 GHz band wireless technology.
When there is a device that uses the same frequency band such as a wireless LAN (IEEE802.11.b/g/n) near your mobile communications device, the communication may not be established.

Calibration

The calibration interval depends on factors such as operating conditions and environment. Please determine the appropriate calibration interval based on your operating conditions and environment and have Hioki calibrate it accordingly on a regular basis.

Cleaning

• If the instrument becomes dirty, moisten a soft cloth with water or a neutral detergent and gently wipe it clean.
• Keep the surfaces clean by gently wiping them with a soft dry cloth. Dirt on the facing core
surfaces of the sensor heads can adversely a󰀨ect the measurement accuracy.
• Wipe the display panel gently with a soft, dry cloth.

Disposing of the Instrument

Dispose of the instrument in accordance with local regulations.

The output rate di󰀨ers from the specications.
The output is small.
The measured value is incorrect.
Troubleshooting
The 200.0 A range is used. Check the current range.
The equipment that receives the output has a low input impedance.
The frequency of the object under measurement is outside the output
accuracy (15 Hz to 2 kHz) range.
Displayed values can frequently uctuate due to induction potential even when no voltage is applied. This, however, is not a malfunction.
The tip of the jaws is open. Close the jaws. The jaws are damaged.
When a jaw is damaged or cracked, the current cannot be measured accurately.
The 200.0 A has an output rate of 200 mV/f.s. This rate di󰀨ers from the
other ranges’ rates . Check the input impedance of the
equipment that receives the output.
An input impedance of 100 k
more is recommended.
The frequency band (15 Hz to 15 kHz) shows a band where the output attenuation is ±3 dB or less. (p. 59)

The measured value does not change.
The jaws generate a
sound (vibration) during
measurement.
The wireless communications cannot be established.
An error is displayed. See p. 65. Have the instrument repaired.

The display is held. Disable the hold function. (p. 27)
When a large magnitude of load
current or a high-frequency current is
measured, resonance sounds may be generated on rare occasions. There
are individual di󰀨erences in loudness of the sound, but it does not a󰀨ect the
measurement.
The Z3210 is not installed. Install the Z3210. (p. 16)
The wireless communications function is disabled.
The settings of the GENNECT Cross are incorrect.
Enable the wireless communications
