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

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

Operating Precautions
Connecting to the Terminals
Connecting to the Analog Input Terminals
• Note the following maximum input voltage and maximum rated
voltage to earth.
600 V AC/DC (CAT III, II), 300 V AC/DC (CAT IV)
If their voltages are exceeded, this device will be damaged and
personal injury will result. Therefore, do not perform measurement in this case.
The maximum allowable input voltage is the smaller of that of the
instrument or of the measurement cables.
• The relationship between the maximum allowable input voltage
and the maximum rated voltage to earth of the combined Memory HiCorder and measurement cables is as follows.
To avoid electric shock or damage to the instruments, do not
apply input voltage above the lowest maximum.
The maximum rated voltage to earth in the table applies when
measuring through input attenuators.

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.

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.
