Measurement categories
To ensure safe operation of measuring instruments, IEC 61010 establishes safety stan-
dards for various electrical environments, categorized as CAT II to CAT IV, and called
measurement categories.
This HiLogger conforms to the safety requirements for CAT II (300 VAC,DC) measuring
instruments.
Difference between "Measurement" and "Recording"
The measurement and recording processes are distinguished as follows for the purposes
of these instructions.
Measured data (data acquired in internal memory) is erased whenever a new measure-
ment starts. To retain data, always record (save) it.
• Using a measuring HiLogger in an environment designated with a
higher-numbered category than that for which the HiLogger is rated
could result in a severe accident, and must be carefully avoided.
• Never use a measuring HiLogger that lacks category labeling in a
CAT II to CAT IV measurement environment. Doing so could result
in a serious accident.
CAT II: When directly measuring the electrical outlet receptacles of the primary electrical
circuits in equipment connected to an AC electrical outlet by a power cord
(portable tools, household appliances, etc.).
CAT III: When measuring the primary electrical circuits of heavy equipment (fixed
installations) connected directly to the distribution panel, and feeders from the
distribution panel to outlets.
CAT IV: When measuring the circuit from the service drop to the service entrance, and to
the power meter and primary overcurrent protection device (distribution panel).
Measurement: The acquisition of input values into internal HiLogger memory or to a PC via
communications.
Recording : Storing measurement data on a CF card, USB flash drive or on a PC via data
communication.

Operating Precautions
6
Follow these precautions to ensure safe operation and to obtain the full benefits of
the various functions.
• Before using the HiLogger the first time, verify that it operates normally
to ensure that no damage occurred during storage or shipping. If you
find any damage, contact your dealer or Hioki representative.
• Before using the HiLogger, make sure that the insulation on the cables
is undamaged and that no bare conductors are improperly exposed.
Using the HiLogger in such conditions could cause an electric shock, so
contact your dealer or Hioki representative for replacements.
Operating temperature and humidity: 0 to 40°C at 80% RH or less (non-
condensating)
Temperature and humidity range for guaranteed accuracy: 23±5°C,
80%RH or less
Installation Precautions
Operating Precautions
Before Use
Instrument Installation
Avoid the following locations that could cause an accident or
damage to the instrument.
Exposed to direct sunlight
Exposed to high tempera-
ture
In the presence of corro-
sive or explosive gases
Exposedtowater, oil,other
chemicals, or solvents
Exposed to high humidity
or condensation
Exposed to strong electro-
magnetic fields
Near electromagnetic radi-
ators
Exposed to high levels of
particulate dust Subject to vibration
Near induction heating
systems
(e.g., high-frequency in-
duction heating systems
and IH cooking utensils)
• Avoid temperature changes around the terminal block. Especially avoid
directed airflow such as from an electric fan or air conditioner vent.Ther-
mocouple inputs are prone to measurement errors.
• When the HiLogger is moved to a location with significantly different
ambient temperature, allow at least 60 minutes for thermal equalization
before measuring.

Operating Precautions
7
Handling the Instrument
To avoid electric shock, do not remove the HiLogger's case. The
internal components of the HiLogger carry high voltages and may
become very hot during operation.
Touching any of the high-voltage points inside the HiLogger is very
dangerous.
Do not attempt to modify, disassemble or repair the HiLogger; as fire,
electric shock and injury could result.
To avoid damage to the HiLogger, protect it from physical shock when
transporting and handling. Be especially careful to avoid physical shock
from dropping.
This instrument may cause interference if used in residential areas. Such
use must be avoided unless the user takes special measures to reduce
electromagnetic emissions to prevent interference to the reception of radio
and television broadcasts..
Handling the Cords and Cables
• Avoid stepping on or pinching cables, which could damage the cable
insulation.
• To avoid breaking the cables, do not bend or pull them.
• To avoid damaging the power cord, grasp the plug, not the cord, when
unplugging it from the power outlet.
Before Turning Power On
Before turning the HiLogger on, make sure the supply voltage
matches that indicated on the AC adapter. Connection to an improper
supply voltage may damage the HiLogger or AC adapter and present
an electrical hazard.
When the power is turned off, do not apply voltage or current to the HiLog-
ger. Doing so may damage the HiLogger.
• After use, always turn OFF the power.
• Brief power interruptions of 40 ms or less will not cause this HiLogger to
malfunction. However, Longer interruptions may cause the HiLogger to
shut itself off, so consider local power conditions before installing, as
appropriate.
• To ensure that recording is not interrupted by power outages, you can
use the 9418-15 AC Adapter and Z1000 Battery Pack together.

Operating Precautions
8
Using the Battery Pack
Be sure to observe the following precautions. Incorrect handling may
result in liquid leaks, heat generation, ignition, bursting and other
hazards.
• Use only the Hioki Model Z1000 Battery Pack. We cannot accept
responsibility for accidents or damage related to the use of any
other batteries.
See: "2.2 Using the Battery Pack (Option)" (p. 32)
• To avoid the possibility of explosion, do not short circuit, disassem-
ble or incinerate battery pack.When storing the HiLogger, make
sure no objects that could short-circuit the connectors are placed
near them.
• The battery pack contains lye, which can cause blindness if comes
into contact with the eyes. Should battery liquid get into your eyes,
do not rub your eyes but rinse them in plenty of water and seek the
immediate attention of a physician.
• To avoid electric shock, turn off the power switch and disconnect
the cables before replacing the battery pack.
• After installing or replacing the battery pack, replace the battery
compartment cover and screw.
• Handle and dispose of batteries in accordance with local regula-
tions.
Observe the following to avoid damage to the HiLogger.
• Use the battery pack in an ambient temperature range of 0 to 40°C and
charge it in an ambient temperature range of 10 - 40°C.
• If the battery packs fails to complete charging within the stipulated time,
disconnect the AC adapter from the pack to stop charging.
• Consult your dealer or nearest service station should liquid leaks,
strange odor, heat, discoloration, deformation and other abnormal condi-
tions occur during use, charging or storage. Should these conditions
occur during use or charging, turn off and disconnect the HiLogger
immediately.
• Do not expose the HiLogger to water and do not use it in excessively
humid locations or locations exposed to rain.
