Operating Precautions
Operating Precautions
Follow these precautions to ensure safe operation and to obtain the full benefits of
the various functions.
Before Use
• Before using the instrument for the first time
, verify
that it operates normally to
ensure that no damage occurred during storage or ship ping. If you find any damage, contact your dealer or Hioki representative.
• Before using the instrument, make sure that the insulation on the cables is undamaged and that no bare conductors are improperly ex
posed. Using the instrument in
such conditions could cause an electric shock, so contact your dealer or Hioki representative for replacements.
Instrument Installation
• Operating temperature and humidity: 0 to 40°C a

Installation Precautions
• If the instrument is used in any state other than the following, the
measurement accuracy may not satisfy the device specifications.
• Leave sufficient space around the ventilation holes and install the
instrument
• Avoid temperature changes around the terminal block. Espe
avoid directed airflow such as from an electric fan or air conditioner

Handling the Instrument
• Do not allow the instrument to get wet, and do not take measurements with wet hands. This may cause an el ectric shock.
• Do not attempt to modify, disassemble or rep
ment; as fire, electric shock and injury could result.
To avoid damage to the instrumen t, 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 interfer
ence to the reception of radio and television broadcasts.

Before Turning Power On
Using the Battery Pack
• For battery operation, use only the HIOKI Model 9780 Battery
Pack. We do not take any responsibility for accidents or
damage related to the use of any other batteries.
See: 2.1, "Using the Battery Pack (Option)" (p. 26)
Using the AC Adapter
• Use only the supplied Model Z1005 AC Adapter. AC adapter
input voltage range is 100 to 240 VAC (with ±10% stability) at
50/60 Hz. To avoid electrical hazards and damage to the
instrument, do not apply voltage outside of this range.
• Turn the instrument off before connecting the AC

• Use only the designated power cord
Use of other power cords may cause fire.

When the power is turned off, do not apply voltage or current to
the connectors. Doing so may damage the instrument.
• After use, always turn OFF the power.
• Brief power interruptions of 40 ms or less will not cause this
instrument to malfunction. However, Longer interruptions may
cause the Memory 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 Z1005 AC
Adapter and 9780 Battery Pack together.
About Inputs and Measurement
• The maximum input voltage (and the maximum rated voltage to earth) for the analog input terminals is
V DC). If these limits are exceeded, the instrument may be
damaged and personal injury or death could occur, so do
not attempt measurement.
• Do not leave the Memory HiLogger connected to test objects
in
environments where a voltage surge might exceed the
dielectric withstand voltage. Doing so could result in damage
to the Memory HiLogger, bodily injury or fat al accident.
• Channels are insulated by semiconductor
voltage beyond the specification is applied between the
channels, the semiconductor relay may short circuit. Please
ensure that a voltage beyond specification, especially a
surge such as a lightning, is never applied. When an abnormal measurement value is observed, please contact your
dealer or Hioki representative for inspection.
The waveform for an open channel may sometimes appear to be
influenced by the signals of the other channels being measured. If
you do not like this, please set the waveform display of the open
channel to OFF or short-circuit the input terminals of the open
channel by connecting the positive and negative terminal.

• Inserting a CF card/USB flash drive upside down, backwards or in the
wrong direction may damage the CF card, USB flash drive, or HiLogger.
• Never eject a CF card /USB flash drive while measuring or when the

• As th e CF card/ USB flash dr ive is sensi tive t o static electr icity, damage
to the CF card/USB flash driv e or wrong operations by the HiLogger
may occur due to static electricity. Please be careful when handling it.
• With some USB flash drives, the HiLogger may not start up if power is

power on first, and then insert the USB flash drive. It is recommended
to try out operation with a USB flash drive before starting to use it for
actual measurements.
• The Flash memory in a CF card/USB flash drive has a limited operating life. After long-term usage, data storage and retrieval become difficult. In this case, replace the CF card/USB flash drive with a new one.
• We cannot provide compensation for data loss in a CF card/USB flash
