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 e
xposed. Using the instrument in
such conditions could cause an electric shock, so contact your dealer or Hioki representative for replacements.

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, disasse

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 interfer

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

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 th

About Inputs and Measurement
• The maximum input voltage (and the maximum rated voltage to earth) for the analog input terminal
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
i
n 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 semiconduc
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
HiLo

• As th e CF card/ USB flash drive is sen sitive t o static elec tricit y, 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
tu
rned 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
d
rive, regardless of content or cause of the damage. Data is also cleared
from memory if a long time passes after measuring. Always maintain a
backup of important data stored on a CF card/USB flash drive.
• Although real-time saving to USB flash drive is supported, a CF card is
r
ecommended for data preserva tion. Performanc e cannot be guaran teed

2.1 Using the Battery Pack (Option)
If commercial power is not available when the AC adapter is connected, the
LR8431-20 Memory HiLogger can operate from the Model 9780 battery pack,
so when using commercial power, the battery pack serves as a backup supply
during power outages.
Charge the battery pack fully before using it the first time.
Be sure to observe the following precautions. Incorrect handling may result in liquid leaks, h
bursting and other hazards.
• Do not use a battery pack other than the 9780 Battery Pack.

When to charge
When powering the instrument from the battery pack without the Model Z1005
AC Adapter, the low battery indicator ( ) is displayed when the battery
charge is depleted, indicating that the battery pack requires charging.
Note that if the Memory HiLogger is turned off under this situation, waveform
data may fail to be backed up, and could be lost.
Approximate charging time:
About 200 minutes at 23°C when recharged at the first appearance of the low
battery indicator.
Approximate continuous battery-only operating time
(When saving data to a CF card at a temperature of 23°C)
* When using a USB flash drive, the continuous operating time may decrease
depending on the particular USB flash drive in use.
• After a full charge, with the LCD backlight always on (default setting):
approximately 2.5 hours
• After a full charge, with the LCD backlight off (five minutes after last keypress): approximately 3 hours

Dead time
When repeating recording is enabled ([Repeat] set to [On])
After a recording length has elapsed, some “dead time” is
needed for internal processing before recording can resume.
Because recording is not available during the dead time,
enable continuous recording (set [Cont] to [On]) if you
need to record without data loss.

When the 60 Hz digital filter is selected, optimum line noise
suppression occurs when the recording length is between
two seconds and one hour.
Noise is suppressed with either 50 Hz or 60 Hz filter selections, although the measurement timing difference between
channels may be increased, depending on the recording
length. Disabling the filter (set to Off) minimizes such timing
differences (to less than 1 ms between channels).
When disabled (set to Off), broken wire detection is also
disabled (p. 51).

About Burn Out Detection
Broken (disconnected) thermocouple wires are detected using a tiny (300 nA) sensing
current. The thermal equivalent of the thermoelectromotive force (thermocouple resistance () times the 300 nA sensing current) is added to the measured value. However,
measurement errors can occur if the thermocouple wire is long or if the wire itself has a
large resistance, in which cases broken wire detection should be disabled (set to Off).

Configure these settings for each pulse channel on which you will be counting

Revolution Measurement Theory
Pulse count is measured using the Memory HiLogger’s

The revolution rate (r) per second during time ts is obtained
by dividing the number of pulses from (t-1) to
ber of pulses per revolution.
Example: Pulses per revolution = 4
When the number of pulses counted in one second is

6.1 About Saving and Loading Data
Depending on file size and CF card or USB flash drive capacity, each folder can store over
1,000 files. However, the file screen display is limited to a maximum of 1,000 files. Also, as
more files are created, more time is needed to start and stop recording. We recommend
setting measurement criteria so that the number of saved files stays below 1,000 whenever
possible.
