Introduction
Thank you for purchasing the HIOKI Model CT6845, CT6845-05 AC/
DC Current Probe. To obtain maximum performance from the device,
please read this manual first, and keep it handy for future reference.
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.
Precautions during Shipment
Handle the device carefully so that it is not damaged due to a
vibration or shock.
Safety
This device is designed to conform to IEC 61010 Safety Standards,
and has been thoroughly tested for safety prior to shipment.
However, using the instrument in a way not described in this
manual may negate the provided safety features. Before using the
instrument, be certain to carefully read the following safety notes.
DANGER
Mishandling during use could result in injury or death,
as well as damage to the device. Be certain that you
understand the instructions and precautions in the
manual before use.
WARNING
With regard to the electricity supply, there are risks of
electric shock, heat generation, fire, and arc discharge
due to short circuits. If persons unfamiliar with electricity
measuring instrument are to use the
instrument, another person familiar with such instruments
must supervise operations.
Notation
In this manual, the risk seriousness and the hazard levels are
classified as follows.
DANGER
Indicates an imminently hazardous situation
that will result in death or serious injury to the
operator.
WARNING
Indicates a potentially hazardous situation
that may result in death or serious injury to the
operator.
CAUTION
Indicates a potentially hazardous situation that
may result in minor or moderate injury to the
operator or damage to the device or malfunction.
Safety Symbols
Indicates hazardous high voltage.
Provides warning that negligent safety check or incorrect
operation presents a significant hazard that could result in
electrical shock, burn injury, or even death to the user.
Indicates the prohibited action.
Indicates the compulsory action.
Symbols Affixed to the Device
Indicates cautions and hazards. When the symbol is
printed on the device, refer to a corresponding topic in the
Instruction Manual.
Indicates that only insulated conductors suited to the
voltage of the conductor under test can be measured.
Symbols for Various Standards
Indicates the Waste Electrical and Electronic Equipment
Directive (WEEE Directive) in EU member states.
Indicates that the product conforms to regulations set out
by the EC Directive.
Usage Notes
Follow these precautions to ensure safe operation and to obtain the
full benefits of the various functions.
DANGER
Do not use the device to measure bare conductors.
Doing so may result in a short-circuit or electrical shock.
Make measurements at a location on an insulated wire
that has a suitable amount of insulation for the circuit
voltage.
The maximum measurable current varies with the
frequency, and the current that can be measured
continuously is limited. Operating the device at less than
this limitation is referred to as derating. Do not measure
currents in excess of the derating curve. Doing so may
result in device damage or malfunction, fire, or burns due
to sensor heating.
