as fire, electric shock and injury could result.

• Avoid obst ructi ng the ventil ation holes on the sides of the instru­ment, as it could overheat and be damaged, or cause a fire.

In the presence of corro­sive or explosive gases

Exposed to strong electro­magnetic fields
Near electromagnetic radi­ators

Near induction heating sys­tems (e.g., high-frequency
induction heating systems
and IH cooking utensils)

10

Operating Precautions

• The operating temperature range of the instrument is -10°C to 50°C.
Do not use the instrument in an environment that is out of this range.

• To avoid damage to the instrument, 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.

• Before transporting the instrument, disconnect all cables and remove
any CFcard, USB flash drive and recording paper.

• Do not slant the device or place it on top of an uneven surface. Drop­ping or knocking down the device can cause injury or da mage to the
device.

• The instrument is equipped with a protector. The physical shock pro­tection provided by the protector does not fully prevent instrument fail­ures. Be sufficiently careful when handling the instrument.

Correct measurement may be impossible in the presence of strong
magnetic fields, such as near transformers and high-current condu c­tors, or in the presence of strong electromagnetic fields such as near
radio transmitters.

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.

• When disconnecting the BNC connector, be sure to release the lock
before pulling off the connector. Forcibly pulling the connector without
releasing the lock, or pulling on the cable, can damage the connector.

• To prevent an electric shock accident, confirm that the white or red
portion (insulation layer) inside the cable is not exposed. If a color
inside the cable is exposed, do not use the cable.

11

Operating Precautions

• Use only the specified connection cables. Using a non-specified cable
may result in incorrect measurements due to poor connection or other
reasons.

• Before using a clamp sensor or logic probe, read the instruction man­ual supplied with it.

12

Operating Precautions

Alkaline Battery Box (Accessory) and Battery Pack (Option)

About installation procedure: "2.1 Using the Alkaline Battery Box (Accessory)
or Battery Pack (Option)" (p. 34)

Be sure to observe the following precautions. Incorrect handling
may result in liquid leaks, heat generation, ignition, bursting and
other hazards.

• For the battery pack, use the optional Z1000 Battery Pack. We do
not take any re sponsib ility for accident s or damage related to the
use of any other batteries.

• When using the alkaline battery box, use commercially available
eight LR6 alkaline batteries.

• To avoid the possibility of explosion, do not short circuit, disas­semble or incinerate battery pack/battery. Handle and dispose of
batteries in accordance with local regulations.

• When storing the instrument, make sure no objects that could
short-circuit the connectors are placed near them.

• The battery pack and alkaline dry cell batteries contain 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 batteries or battery pack.

• After installing or replacing the batteries or battery pack, replace
the battery compartment cover and screws.

• Handle and dispose of batteries or battery pack in accordance
with local regulations.

About alkaline dry cell batteries

• Do not mix old and new batteries, or different types of batteries. Also,
be careful to observe battery polarity during installation. Otherwise,
poor performance or damage from battery leakage could result.

• Do not use LR6 alkaline batteries together with commercially avail­able nickel hydride batteries or other types of batteries.

• To avoid corrosion an d damage to this instrument from battery leak­age, remove the batteries from the instrument if it is to be stored for a
long time (several months or more).

When using battery pack

Observe the following to avoid damage to the instrument.

• Use the battery pack in an ambient temperature range of 0 to 40°C
and charge it in an ambient temperature range of 10 to 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
conditions occur during use, charging or storage. Should these condi­tions occur during use or charging, turn off and disconnect the instru­ment immediately.

• Do not expose the instrument to water and do not use it in excessively
humid locations or locations exposed to rain.

• Do not expose the instrument to strong impacts and do not throw it
around.

13

Operating Precautions

14

Operating Precautions

• The battery pack is a consumable. If the battery capacity remains very
low after correct recharging, the useful battery life is at an end.

• When a battery pack that has not been used for a long time is used,
charging may end before the battery pack is fully charged. In such a
case, repeat charging and discharging a number of time before use.
(A battery pack may also be in such a state immediately after pur­chase.)

• The life of the battery pack (when capacity is 60% or more of initial
capacity) is approximately 500 charge-discharge cycles. (The life dif­fers depending on the conditions of use.)

• To prevent battery pack deterioration when the battery will not be
used for 1 month or longer, remove it and store it in a dry location with
an ambient temperature range of between -20 to 30°C. Be sure to dis­charge and charge it every two months. Long-term storage when
capacity has decreased will make charging impossible and reduce
performance.

• When a battery pack is used, the instrument turns off automatically
when the capacity drops. Leaving the instrument in this state for a
long time may lead to over discharge so be sure to turn off the power
switch on the instrument.

• The charging efficiency of the battery pack deteriorates at high and
low temperatures.

Using the AC Adapter

• Use only the supplied Model Z1002 AC Adapter. AC adapter
input voltage range is 100 to 240 V AC (with ±10% stability) at 50/
60 Hz. To avoid electrical hazards and damage to the instrument,
do not apply voltage outside of this range.

• Before connecting to a power supply, make sure the supply volt­age matches that indicated on the AC adapter. Connection to an
improper supply voltage may damage the instrument or AC
adapter and present an electrical hazard.

• Turn the instrument off before connecting the AC adapter to the
instrument and to AC power.

• To avoid electrical accidents and to maintain the safety specifi­cations of this instrument, connect the power cord provided only
to a 3-contact (two-conductor + ground) outlet.

• If you wish to use a UPS (uninterruptible power supply) or DC-AC
inverter to power the instrument, do not use a UPS or DC-AC inverter
with square wave or pseudo sine wave output. Doing so may damage
the instrument.

• To avoid damaging the power cord, grasp the plug, not the cord, when
unplugging it from the power outlet.

15

Operating Precautions

• 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 HiCorder 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 Z1002 AC Adapter and Z1000 Battery Pack together.

Operating Precautions

Connect the clamp-on sensors or connection cords to the instru­ment first, and then to the active line s to be measured. Observe
the following to avoid electric shock and short circuits.

• To avoid short circuits and potentially life-threatening hazards,
never attach the clamp to a circuit that operates at more than the
maximum rated voltage to earth, or over bare conductors.

• Do not allow the connection cord clips to touch two wires at the
same time. Never touch the edge of the metal clips.

• When the clamp sensor is opened, do not allow the metal part of
the clamp to touch any exposed metal, or to short between two
lines, and do not use over bare conductors.

• Do not leave the Memory HiCorder 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 HiCorder, bodily injury or fatal accident.

• Do not connect a cable to the instrument while it is connected to
the object to be measured. Otherwise, an electric shock accident
may occur.

• To avoid short-circuit accidents, make certain that connections
are secure.

To prevent damage to the instrument and sensor, never connect or dis­connect a sensor while the power is on, or while th e sensor is cla mped
around a conductor.

• Lay the connection cords and various cables away from the power
supply line and ground wire.

• Connecting the connection cords and various cables in a parallel con­figuration with the inputs of another device (see the figure be low) may
result in variations in measurement values and incorrect operation of
the instrument. When connecting with another device in a parallel
configuration, be sure to verify operation.

Object

Memory
HiCorder

Logic
Probe

Operating Precautions

Connecting to the logic terminals

To avoid electric shock and short circuit accidents or damage to
the instrument, pay attention to the following:

• Maximum logic probe input voltages are as follows.
Do not measure if the maximum voltage would be exceeded, as
damage the instrument or personal injury may result.
Model 9320-01 Logic Probe: +50 V DC
Model MR9321-01 Logic Probe: 250 Vrms (HIGH range), 150 V rms
(LOW range)

• The ground terminal for the 9320­01 Logic Probe is not isolated
from the Memory HiCorder's
ground (chassis ground). There­fore, if the measurement object
connect to AC, it should have a
grounded, polarized plug, and be
connected to the same power outlet as the Memory HiCorder ’s
AC adapter.
If the Memory HiCorder and measurement object are connected
to different mains circuits, or if an ungrounded power cord is
used, the potential difference between the different grounding
paths may result in current flow through a logic probe that could
damage the measurement object or Memory HiCorder.

• Do not allow the metal tip of a logic probe to cause a short
between conductors on the measurement object. Never touch
the metal tip of a probe.

When connecting USB cable

• To prevent a malfunction, do not disconnect the USB cable during
communication.

• The Memory HiCorder and computer should be connected to the
same earth ground. If grounded separately, potential difference
between the ground points can cause malfunctions or damage when
connecting the USB cable.

This instrument cannot be powered by the bus of a PC or USB hub.
When using the instrument, connect the AC adapter or install batteries.

When connecting to external control terminals

To avoid electric shock or damage to the equipment, always
observe the following precautions when connecting to external
control terminals.

• Always turn off the power to the instrument and to any devices
to be connected before making connections.

• Be careful to avoid exceeding the ratings of external control ter­minals.

• Ensure that devices and systems to be connected to the exter­nal control terminals are properly isolated.

• The ground of external control terminals and the ground of the
instrument are common and not isolated.
To prevent damage to the instrument, use a grounded power
cord for the device to be connected with the external control ter­minals and this instrument, and supply power from the same
line. Using different lines or an ungrounded power cord may
result in a potential difference between the grounds depending
on the wiring state, and current flowing through the wiring mate­rial may lead to damage of the measurement object or instru­ment.

• To prevent an electrical accident, use wiring material that has
more than enough dielectric strength and current-carrying
capacity.

19

Operating Precautions

If a cable of 3 meters or longer is connected, the instrument may be
susceptible to the interference of external noise and other EMC envi­ronmental factors.

20

Measurement data (data captured to internal buffer memory) is
cleared when new measurements are started. If you want to
keep any data, be sure to save it to external media.

Operating Precautions

About the Printer

• The printer head and metal parts nearby become very hot. Be
careful not to touch them because doing so may result in a burn.

• Be careful not to cut a finger with the paper cutter.

• To prevent a malfunction o f the instrument, turn off the power when
connecting the instrument and printer unit.

• Do not directly touch the printer head because there is the risk of it
being damaged by static electricity.

As much as possible, avoid printing in hot and humid environments.
Otherwise, printer life may be severely shortened.

Using a CF Card/ USB Flash Drive

• Inserting a CF card/USB flash drive upside down, backwards or in the
wrong direction may damage the CF card, USB flash drive, or instru­ment.

• Never remove a CF card or USB flash drive during measurement
while the instrument is accessing the CF card or USB flash drive. The
CF card or USB flash drive and/or the data on it may be damaged.
(The icon of the CF card or USB flash drive on the bottom left of the
screen is displayed in red during access.)

• Do not transport the instrument while a USB flash drive is connected.
Damage could result.

• Some USB flash drives are susceptible to static electricity. Exercise
care when using such products because static electricity could dam­age the USB flash drive or cause malfunction of the instrument.

• With some USB flash drives, the instrument may not start up if power is
turned on while the USB flash drive is inserted. In such a case, turn
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
drive, regardless of content or cause of the damage. Furthermore, if a
long time has elapsed since data was recorded to a file, the stored
data may be lost. Always maintain a backup of important data stored
on a CF card/USB flash drive.

• Data can also be saved to a USB flash drive in real time, but from the
perspective of data protection, we recommend using Hioki’s optional
CF card. The operation of media other than Hioki’s optional products
is not guaranteed.

CD Handling

• Always hold the disc by the edges, so as not to make fingerprints on
the disc or scratch the printing.

• Never touch the recorded side of the disc. Do not place the disc
directly on anything hard.

• Do not wet the disc with volatile alcohol or water, as there is a possi­bility of the label printing disappearing.

• To writ e on the disc label surface, use a spirit-based felt pen. Do not
use a ball-point pen or hard-tipped pen, because there is a danger of
scratching the surface and corrupting the data. Do not use adhesive
labels.

• Do not expose the disc directly to the sun's rays, or keep it in condi­tions of high temperature or humidity, as there is a danger of warping,
with consequent loss of data.

• To remove dirt, dust, or fingerprints from the disc, wipe with a dry
cloth, or use a CD cleaner. Always wipe from the inside to the outside,
and do no wipe with circular movements. Never use abrasives or sol­vent cleaners.

• Hioki shall not be held liable for any problems with a computer system
that arises from the use of this CD, or for any problem related to the
purchase of a Hioki product.

2.6 Turning the Power On and Off

Right Side

Turn the power
switch on ( ).

The power supply icon ap­pears near the bottom right
corner of the screen (p. 31).

If the " " indicator is not displayed, the instrument is not being pow­ered from the AC line. In this state, the battery charge will be depleted if
measuring for a long time, and measurement may be interrupted. Verify
that the AC adapter is securely connected to an AC power source and
to the instrument.

Turning Power On

Turn the POWER switch off ( ).

The installed battery pack is charged whenever the AC adapter
is plugged into a power outlet, even when the Memory HiCorder
is off. In addition, providing there is some remaining battery
charge, waveform data and the setting configuration are memo­rized whenever the Memory HiCorder is turned off, so that when
the Memory HiCorder is turned back on, the same operating
state is displayed.

Verify that the instrument and peripheral devices are
correctly connected.

Turning Power Off

The accuracy of the instrument is guaranteed under the condition that the
instrument has been warmed up for at least 30 minutes.
To ensure accuracy is met, execute zero adjustment approximately 30 min­utes after turning the power on. (p. 51)

 About zero position offset of analog input circuits

With this instrument, the zero position may be off­set in a high sensitivity range (10-mV/div range,
etc.). Furthermore, the accuracy of the instrument
is guaranteed under the condition that the instru­ment has been warmed up for at least 30 minutes.
The figure on the right shows the representative
characteristics of zero position drift from immedi­ately after the power is turned on. The changes in
the zero position are relatively large for 30 minutes
after the power is turned on. The existence of
these characteristics means that zero adjustment
must always be executed before measurements
are taken. In particular, when you will take mea­surements for a long time or take high-precision
measurements, we recommend 60 minutes of ag­ing before executing zero adjustment.

4.2 Recording Methods
(Measurement Functions)

As recording methods, the instrument has two measurement functions, high speed
and real time. The internal processing for saving and printing and the setting items
on the measurement screen differ depending on the function.

The measurement function can be set on the Waveform screen and Setting screen
of the instrument.

4.2 Recording Methods (Measurement Functions)

Sampling is performed at high speed so
the data is first stored in the internal buf­fer memory. The data stored in the inter­nal buffer memory is displayed on the
screen, saved to the storage media, and
printed after measurement ends.

Sampling is performed at low speed so
the waveform is displayed and the data
is saved to the storage media and print­ed* during sampling.

Set the time per division of the horizontal
axis (time base).

The fastest time base that can be set is
100 µs/div, which is 1 MS/s when con­verted to sampling speed. (At the magni­fication of x1, the number of data per
division is 100.)
By changing the setting, you can
set the time interval at which to
perform sampling in the same
way as shown on the right.

Set the time interval to perform sampling.

The maximum sampling interval is 100
µs, which is 10 kS/s when converted to
sampling speed.

Two setting procedures are available: setting the time
per division of the horizontal axis and setting the data
acquisition interval.

• When setting the time per division of the horizontal
axis
The data of 100 samples is included in 1 division.
(When the magnification is x1)
Sampling rate = timebase (seconds/div)/100 (data
samples/division)

• When setting the data acquisition interval (p. 74)
(It is possible to switch to the same setting proce­dure as for the Real-time Function.)
Select the recording interval that matches the mea­surement target. If a short recording interval is selected, the recording time for
which data can be stored in the internal buffer memory will be short.

Retaining Records of Maximum and Minimum Values (Envelope)

The maximum and minimum values within the

recorded for each recording interval. Therefore,
recording without missing the peak of fluctuation will
be possible even if a long recording interval is set.
(*): Sampling is the acquiring of the data to be saved
to the internal buffer memory. Oversampling is the acquiring of data at a higher
speed than when data is acquired to the internal buffer memory (sampling). Over­sampled data is not saved.

oversampling during the set re­cording interval.
When displaying them on the

Setting the Input Channel (Instant aneous V alue/Effective V alue & Measurement Range)

This section describes the minimum required settings for measurement.
The input channel mode (instantaneous value/effective value recording) and mea­surement range need to be set before measurement. Change the settings of oth er
setting items as necessary.

• The frequency range for effective values that can be measured with
the instrument is 30 Hz to 10 kHz. An effective value of a frequency
that is out of this range cannot be measured correctly.

• When effective value measurement is perform ed, the response time
becomes long if the input voltage is 10% f.s. or less. We recommend
configuring the setting so that the input voltage becomes 10% f.s. or
more.

• The input signal is displayed as fo llows when it exceeds the possible
measurement range of the set measurement range.
Measurement waveform: The data that exceeds the possible mea­surement range is displayed in white when the screen backgroun d is
black, and in black when the screen background is white.
Measurement values: The data that exceeds the possible measure­ment range is indicated as "OVER."
