To avoid electric shock, do not remove the instrument's case. The internal
components of the instrument carry high voltages and may become very
hot during operation.
Never modify the instrument. Only Hioki service engineers should disas-
semble or repair the instrument. Failure to observe these precautions may
result in fire, electric shock, or injury.
To avoid damage to the instrument, protect it from physical shock when trans-
porting and handling. Be especially careful to avoid physical shock from drop-
ping.
This instrument may cause interference if used in residential areas. Such use
must be avoided unless the user takes special measures to reduce electromag-
netic emissions to prevent interference to the reception of radio and television
broadcasts.

• Avoid stepping on or pinching cables, which could damage the cable insula-
tion.
• To avoid breaking the cables, do not bend or pull them.
Use only the specified cables. Using a non-specified cable may result in incor-
rect measurements due to poor connection or other reasons.
Handling the CD

Operating Precautions
8
• 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 write 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 sur-
face 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 radially 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.

Chapter 1 Overview
The 8423 Memory HiLogger is a computer based data collection instrument. A
combination of four types of unit can be connected to enable the measurement
of up to 120 channels with one Memory HiLogger. Furthermore, the synchronous
operation of a maximum of five Memory HiLoggers enables you to build a sys-
tem with up to 600 channels. The instrument transfers the measurement data to
the computer in real time. The instrument can also be used not just for computer
based data collection but also as a standalone instrument. (Measurement with
just this instrument is referred to as “standalone” within this manual.) In either
case, set the measurement conditions with the supplied software Logger Utility.
See "2.1 Installing Logger Utility" (p. 18).

The fastest recording interval is 10 ms, during which the input data of all chan-
nels is scanned. The recording intervals can be set in 19 steps from 10 ms to 1
hour.
* The recording interval is 5 seconds or longer when one or more channels are
set to humidity measurement.
A maximum of eight units can be connected to one 8423 Memory HiLogger to
enable the measurement of up to 120 channels. Furthermore, the synchronous
operation of five Memory HiLoggers facilitates the synchronized measurement of
600 channels.
The input circuits of all of the channels are isolated*. The maximum rated voltage
to earth is 600 VAC/DC, so voltage can be measurement safely.
* 8948 Voltage/Temp Unit and 8949 Universal Unit only.
For the 8996 Digital/Pulse Unit, each 3 blocks of 5 channels are isolated within
the unit.
A combination of 2 types of recording interval can be set within the system. The
recording intervals can be set individually by unit. Measuring with a recording
interval suitable for each measurement object allows for efficient use of space in
the internal memory or CF card.
See "5.3.1 Setting Function and Recording Interval" (p. 77).
The following four types of unit can be used in accordance with the purpose of
use. The input terminal block is removable to enable connections to be made
easily.
• Model 8948 Voltage/Temp Unit and 8949 Universal Unit
There are 15 channel inputs per unit. Measurement is possible for voltage,
nine types of thermocouple, two types of resistance temperature detector*,
and humidity* (an optional sensor is required).
* Model 8949 Universal Unit only
• Model 8996 Digital/Pulse Unit
There are 15 channel inputs per unit. Logic input and pulse input can be set
for each channel. Logic signal, totalization, and rotation rate measurement are
possible.
• Model 8997 Alarm Unit
There are 15 channel outputs per unit. Alarm output (open collector output)
allows for controlling external devices.

Chapter 1 Overview
Connecting multiple Memory HiLoggers with optional 9683 Connection Cable
(for synchronization) allows for synchronized measurement. See "3.7 Connect-
ing Synchronization Cables" (p. 48).
The instrument is compatible with LAN 100BASE-TX and USB2.0. A computer
and Memory HiLogger can be connected to enable the supplied software Logger
Utility to be used to control the Memory HiLogger and collect data.
This allows you to save the setting conditions and the measurement data in real
time to a CF card. While data is being saved to the CF card in real time, you can
replace the CF card without stopping measurement. Furthermore, the risk of files
being damaged as a result of, for instance, an unexpected power outage is
greatly reduced because internal backup circuitry is used to process the ending
of files when there is a power outage.
The Memory HiLogger can be controlled by inputting a signal from an external
device. This allows for the starting and stopping of measurement, external sam-
pling, and external triggers.
After settings such as the measurement conditions have been configured from
Logger Utility, you can disconnect the computer and then start/stop measure-
ment with or on the instrument.
