Introduction
Thank you for purchasing the HIOKI Model CT6862, CT6863,
CT6862-10, CT6863-10, CT6862-05 and CT6863-05 AC/DC
Current Sensor.To obtain maximum performance from the device, please read this manual first, and keep it handy for future
reference.
Usage with Other Hioki Products
This device is used in connection with a dedicated instrument
(Hioki). See “Specifications” for details.
Inspection
When you receive the device, inspect it carefully to ensure that
no damage occurred during shipping. In particular, check the
accessories and cables. If damage is evident, or if it fails to operate according to the specifications, contact your dealer or Hioki representative.
Overview
The CT6862,CT6862-05 (up to 50 A) and CT6863,CT6863-0 5
(up to 200 A) are the feed-thr oug h cu rren t se nsors designed to
measure AC/DC current with high precision. Featuring good frequency characteristics (amplitude & phase) and good temperature characteristics (sensitivity & offset), the sensor is also
suitable for high-precision power measurements.
The Model CT6862-10 a nd CT 686 3-10 i s a c urr ent se ns or tha t
supports even higher-accuracy power measurement when used
in combination with the Model 3390-10 Power Analyzer.

safe operation of th e de vi ce an d for m ain tainin g i t in safe operating condition. Before using it, be sure to carefully read the following safety precautions.
This device is designed to comply with IEC 61010
Safety Standards, and has been thoroughly tested for
safety prior to shipment. However, mishandling during
use could result in injury or death, as well as damage to
the device. However, using the device in a way not
described in this manual may negate the provided
safety features. Be certain that you understand the
instructions and precautions in the manual before use.
We disclaim any responsibility for accidents or injuries
not resulting directly from device defects.
Safety Symbol
In the manual, the symbol indicates particularly important
information that the user should read before using the device.
The symbol printed on the device indicates that the user
should refer to a co rresponding topic in the manua l (marked
with the symbol) before using the relevant function.
Indicates a double-insulated device.
The following symbols in this manual indicate the relative importance
of cautions and warnings.
Indicates that incorrect operation presents an extreme hazard that could result in serious injury or death to the user.
Indicates that incorrect operation presents a significant hazard that could result in serious injury or death to the user.

Measurement categories
This device complies with CAT III safety requirements.
To ensure safe ope ratio n of measu reme nt devic es, IEC 61 010 establ ishes safety
standards for various elect rical enviro nments, categorize d as CAT II to CAT IV, and
called measurement categories.
CAT II: Primary electrical circuits
in equipment connected
to an AC electrical outlet
by a power cord (portable
tools, household appliances, etc.)
CAT II covers directly
measuring electrical outlet receptacles.
CAT III:Primary electrical circuits
of heavy equipment (fixed installations) connected directly to the distribution panel, and feeders from the distribution panel to outlets.
CAT IV:The circuit from the service drop to the service entrance, and to the pow-
er meter and primary overcurrent protection device (distribution panel).
Using a measurement device in an environment designated with a higher-numbered category than that for which the device is rated could result in a severe accident, and must be carefully avoided.
Use of a measurement instrument that is not CA T-rat ed in CA T II to CA T IV measurement applications could result in a severe accident, and must be carefully
avoided.
Operating temperature and humidity：-30 to 85°C, 80%RH or less (non-condensation)
Avoid the following locations that could cause an accident or damage to the
instrument.
Exposed to direct
sunlight
Exposed to high
temperature
Exposed to wa ter , oi l, othe r
chemicals, or solvents
Exposed to high humidity
or condensation
Exposed to high levels of
particulate dust
Subject to vibration
In the presence of
corrosive or explosive
gases
Exposed to strong
electromagnetic fields
Near electromagnetic
radiators
Near induction heating
systems (e.g., highfrequency induction
heating systems and IH
cooking utensils)
Usage Notes
Follow these precautions to ensure safe operation and to obtain
the full benefits of the various functions.
Preliminary Checks
Before using the device the first time, verify that it operates normally
to ensure that the no damage occurred during storage or shipping.
If you find any damage, contact your dealer or Hioki representative.
• This device should only be connected to the secondary
side of a breaker, so the breaker can p revent an accident if a short circuit occurs. Connections should
never be made to the primary side of a breaker,
because unrestrict ed current flow could cau se a serious accident if a short circuit occurs.
• The maximum rated voltage between input terminals
and ground is 1000 V DC/AC. Attempting to measure
voltages exceeding 1000 V with respect to ground
could damage the device and result in personal injury.
• Before using the devic e, make sure that the insu lation
on the cable is undamaged and that no bare conductors are improperly exp osed. Using th e device in such
conditions could cause an electric shock, so contact
your dealer or Hioki representative for repair.
• In order to prevent electric shock and short-circuit
accidents, shut off the power to the line to be measured before connecting this device.
• Ensure that the input does not exceed the maximum
input voltage or current to avoid device da mage, shortcircuiting and electric shock resulting from heat building.
• Avoid contact between the cable and the measured line
in order to protect the cable from damage. Any contact
can cause the d evice to malfunction and lead to shortcircuits or electric shock.
• This device is not drip-proof. Water droplets on the connector may result in malfunctions.
• Do not slant the device or pla ce it o n to p of a n un ev en s urface. Dropping or knocking down the device can cause injury or damage to the device.
• Avoid stepping on or pi nching cables, which could damage
the cable insulation .
• Keep the cables well away from heat sources, as bare conductors could be exposed if the insulation melts.
• To avoid damage to the device, protect it from physical
shock when transportin g and handlin g. Be especi ally careful to avoid physical shock from dropping.
• The cable is hardened under the 0 degree or colder environment.
Do not bend or pull it to avoid tearing its shield or cutting cable.
• When the power to lines to be measured is turned on or off,
a current flowing through the lines can exceed considerably
the maximum allowable current of the device. This could result in damage to the device. Make sure that there is not any
over-current.
• Do not apply any current through th e lines to be measur ed with
the device turned off. This could result in damage to the device.

Measurement Procedure
In order to prevent elect ric shock and short-cir cuit accidents, shut off the power to the line to be measured
before connecting this device.
• To prevent damage to the sensor and connected instrument,
never connect or d isco nn ec t a se nso r wh il e t he powe r is on .
• When the connected instrument’s power is turned off, do not
apply current to the sensor . Doing so m ay damage the device.
• When disconnecting the output connector, be sure to release the lock before pulling off the connector. Forcibly pulling the connector without releasing the lo ck, or pulling on
the cable, can damage the connector.
The sensor's signal output circuit is protected by a resistor (output resistor). A digital multimeter used for monitoring should
have high input resistance (recommended minimum: 1 MΩ).
Wiring
Make sure the direction of the arrow on the case matches the
direction of the current flow, as shown in Figure 1. If they are oriented incorrectly, the output signal fr om the sensor will be reversed.
Maintenance Service
Do not attempt to modify, disassemble or repair the
device; as fire, electric shock and injury could result.
• To clean the device, wipe it gently with a soft cloth moistened
with water or mild detergent. Never use solvents such as
benzene, alcohol, acetone, et her, ketones, thinners or gasoline, as they can deform and discolor the case.
• If the device seems to be mal func tioni ng, c ontact your dea le r
or Hioki representative. When r eturning the dev ice for repair,
pack the device so that it will not sustain damage during shipping, and include a desc ription of existing da mage. We cannot accept responsibility for damage incurred during
shipping.
