Operating Precautions

Handling the Cables

Handling the CD

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.

• 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 incor­rect measurements due to poor connection or other reasons.

8

Operating Precautions

• 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 ball­point 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 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

Overview Chapter 1

1.1 Product 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 sys­tem 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).

1.2 Features

1.2 Features

10 ms Recording Intervals*

The fastest recording interval is 10 ms, during which the input data of all chan­nels 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.

Multiple Channels (Up to 600 Channels)

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.

Isolated Input Circuits

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.

Dual Sampling

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).

Flexible System Configuration

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.

11

1.2 Features

Synchronized Measurement

Connecting multiple Memory HiLoggers with optional 9683 Connection Cable
(for synchronization) allows for synchronized measurement. See "3.7 Connect­ing Synchronization Cables" (p. 48).

Equipped with LAN & USB Interfaces

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.

Equipped with CF Card Slot

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.

Equipped with External Control Input Terminals

The Memory HiLogger can be controlled by inputting a signal from an external
device. This allows for the starting and stopping of measurement, external sam­pling, and external triggers.

3.2 Connecting a Cable to the Terminal Block

• Be sure to attach the removed terminal block to the unit to which it was origi­nally attached.

• Since the structure of a terminal block is designed so that it cannot be attached
to a unit of a different type, using excessive force to try to attach a terminal
block to the wrong unit will damage the connector.

When you want to mark a terminal block and unit:

Use the mark area on the front of the unit for writing a number, comment, or
other information. If you use a pencil, you can erase the writing by just gently
wiping it off. It is convenient to mark the removed terminal blocks and the units
to help you remember which block to attach to which unit.

To connect a cable to a terminal block, lift up the cover at the front and then con­nect the cable to the terminal block.

• In order to prevent electric shock and short-circuit accidents, shut off the power
to the line to be measured before connecting the input cable.

• To avoid electrical accidents, confirm that all connections are secure. The
increased resistance of loose connections can lead to overheating and fire.

• Channels are isolated by semiconductor relays. Never apply a voltage in
excess of the specifications between channels as doing so could damage the
semiconductor relays by causing them to short out. Exercise particular care
concerning surge protection against lightning and other threats. If the instru­ment yields erroneous measured values, have it inspected.

Be sure to pull out an input cable after you loosen the screws of the terminal
block. The input cable will be damaged if the screws are not loosened and
excessive force is used to pull out the input cable.

3.2 Connecting a Cable to the Terminal Block

• If an input cable of 3 m or longer is connected, measurement may be affected

by external noise and other electromagnetic interference.

• The general guidelines for resistance temperature detector terminations are pro-

vided in JIS Z 8704, in which A and B signals are designated by red and white
wires, respectively. However, the three-wire IEC guidelines define the connec­tions differently (red and white are reversed), so special attention is required.

• The measurement current for a resistance temperature detector is 1 mA.

• Connect the cable while it is disconnected from the power line and ground wire.

• Be sure to close the terminal block cover, and tighten the screw.

• If the cable is connected in parallel with another device, there may be varia­tions in the measurement values. When connecting in parallel, confirm opera­tion before use.

• In the case of the SoL terminal (8949 Universal Unit only) for connecting a
resistance temperature detector or 9701 Humidity Sensor, all channels are
common internally and not insulated.

• Make sure the ambient temperature around the terminal block does not
change. In particular, make sure there is no ventilation fan, air conditioner, or
the like blowing air directly onto the terminal block.

• When using crimp-type terminals for connecting to the terminal block of the
8948 Voltage/Temp Unit, 8996 Digital/Pulse Unit, or 8997 Alarm Unit, use ter­minals with insulating coating that are for M3 screws and of the size shown in
the figure below.

• The following cable is recommended for connecting to the terminal block of the
8949 Universal Unit.

Single strand: 0.14 to 1.5 mm

Multi-strand: 0.14 to 1.0 mm

AWS: AWG26 to AWG16
Standard insulation stripping length: 5 mm

• 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.

2. When the eject button pops out, press it in again to eject the CF card.

• Be sure to close the cover after inserting a CF card. Measurement data will
not be saved to the CF card if the cover is not closed.

• When measurement will be performed for a long period of time, first, back up
all files on the CF card by copying them to a drive on the computer. Then, for­mat the CF card so that there are no unnecessary files. It is recommended to
perform a backup and format each time you measure.

• If the cover of the CF card slot cannot be closed properly, submit the instru­ment for repair. Recording to the CF card may stop if, for instance, vibration
causes the cover to open during measurement.

3.6 Using a CF Card

3.6.3 Replacing a CF Card during Measurement

While data is being saved to a CF card in real time, you can replace the CF card
without stopping measurement.

1. Open the CF card slot cover.

47

2. Confirm that the CF card access LED is off, and then eject the CF card.

3. Insert a CF card with sufficient available space, and then close the cover.

As the CF card is sensitive to static electricity, damage to the CF card or wrong
operations by the HiLogger may occur due to static electricity. Please be careful
when handling it.

• The CF card access LED may sometimes be lit red immediately after you open
the cover, because the CF card is being processed. Ejecting the card in such a
state will result in the files of the CF card being damaged. Always make sure
the LED is off before ejecting a CF card.

• Be sure to close the cover after inserting a CF card. Measurement data will not
be saved if the cover is not closed.

• If the CF card is not replaced within 5 minutes, the data of the internal memory
may overflow and the measurement data may not be saved.

• If measurement ends while no CF card is inserted, the data up until the end of
measurement will not be saved even if you insert a CF card afterwards. In
such a case, you can use the HTTP function to extract the data in the instru­ment while the instrument is connected to the LAN. See "Chapter 11 Commu­nications (HTTP/FTP)" (p. 209).

3.6.4 File Protection during Power Outage

The instrument has a large built-in capacitor that processes the ending of files
when the power is switched off or there is a power outage. This greatly reduces
the risk of files being damage by an unexpected power outage.

A CF card cannot be accessed for 30 seconds immediately after the power is
turned on because the large capacitor is being charged.

3.7 Connecting Synchronization Cables

Connecting multiple Memory HiLoggers with optional 9683 Connection Cables
(for synchronization) and using the supplied software Logger Utility to set syn­chronized measurement allows you to synchronize the sampling of the loggers
and perform synchronized measurement with up to 600 channels. In such a
case, you can share trigger function and event mark information, as well as per­form an external start, external stop, and synchronization by external sampling.
For external sampling, input a sampling signal to the master Memory HiLogger.
It is possible for multiple loggers connected by the 9683 Connection Cables (for
synchronization) to measure at the same timing.

* Master:

Generates a synchronization clock to adjust the sampling of slaves 1 to 4.

2. Connect all of the Memory HiLoggers to be used for synchronized mea-

surement to the computer with LAN or USB cables.

3. Register the loggers in Logger Utility, and then set synchronized measure-

ment.

See "Chapter 5 Setting Measurement Conditions" (p. 63).

• The synchronization settings can also be set on the instrument.

• Synchronized measurement is possible with two to five loggers. Synchronized
measurement is not possible with one or six or more loggers.

• Multiple masters cannot be assigned to one measurement system.

• The sampling clock is transferred via the 9683 Connection Cables during syn­chronized measurement. Never disconnect the 9683 Connection Cables dur­ing measurement, because the supply of the clock will stop.

• The IN and OUT connectors of a 9683 Connection Cable differ. Do not use
excessive force to insert a connector.

• Turn on the power of all 8423 Memory HiLoggers connected with the 9683
Connection Cables.

Input Terminals

Inputting a signal from an external device enables the input signal to be a trigger
source, and measurement to be started and stopped. Furthermore, you can col­lect data (external sampling) at any timing with which you want to measure.

To avoid electrical hazards and damage to the instrument, do not apply voltage
outside of the range (DC -5 to 10 V) to the External control input terminals.

To avoid electric shock or damage to the equipment, always observe the follow­ing precautions when connecting to External control input 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 terminals and connectors.

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

• The GND of the external control input terminals and the GND of the Memory
HiLogger main unit are not commonly insulated. To avoid damaging the instru­ment, make sure wiring is done in such a manner that no potential difference
can result between the GND of the external control input terminals and the
GND of the equipment or device to be connected.

• To avoid electric shock, use the recommended
wire type to connect to the current input termi­nals, or otherwise ensure that the wire used has
sufficient current handling capacity and insula­tion.

5.1 Registering Loggers in Logger Utility

This section describes registering loggers in Logger Utility, and configuring the
connection settings for communication. There are two methods for registering
loggers: searching for loggers connected to the computer and then registering
them, or configuring settings manually. The search and register method can be
used for a logger connected to the computer by a USB cable or a logger con­nected to the same network by a LAN cable. Searching is not possible if the net­work is split by, for instance, a router during LAN communication. In such a case,
register loggers manually. (p. 68)

5.1.1 Searching and Registering

Search for loggers connected to the computer, and register the loggers for mea­surement from the found loggers. Up to 256 loggers can be found, and up to 5 of
them can be registered. Connect the computer and loggers by LAN cable or
USB cable beforehand.

The logger uses the TCP/IP protocol during communication. TCP/
IP allows each communication device to establish multiple connec­tions, so port numbers are used to differentiate between the con­nections. The logger uses a pre-defined number from 8800 to

8009. There is normally no need to change a port number, but if
there is a port that cannot be used because of a network security
problem, change the value. The first digit of the port number is
reserved.

When connecting to a network: If the computer is on a different
network than the logger, set this to ON and specify the device that
will be the gateway. If they are connected to the same network,
generally this should be set to same gateway as the computer.
When connecting directly to the computer: This setting is not nec­essary if the computer and logger are connected to the same hub,
so set it to OFF. If DHCP is set to ON, the setting is configured

Communication Problems

Have you completed the LAN setting before connection?

The LAN setting is initialized when all the settings for communications have been made.
Be sure to complete this LAN setting before you connect the instrument to the network.
When you edit the settings while the instrument is connected to the network, you may ac­cidentally send illegal address information to the network. For example, you may select
the same IP address as that of another instrument on the network.

Is the LAN cable connected properly?

When you make one-to-one connection between the instrument and a PC, you must use
a cross cable.
The short cable of the straight-cross converter supplied with the 9642 LAN CABLE is a
cross cable. The connector is a straight male-female converter.
The cable might not be connected to the connector properly. Remove the cable and then
connect it again.

Have you set the IP address of the PC correctly?

Choose [Run] from the Start menu. Type [ipconfig /all] and click [Enter]. Doing so will
enable you to get the IP address of the PC's network interface, subnet mask, and gateway
address.
When the IP address setting is not correct
Choose [Settings]-[Control Panels] from the Start menu.
Double-click the [Network] icon to get the Network Properties dialog box.
Edit the IP address setting.

Chapter 5 Setting Measurement Conditions

Can the instrument communicate with the PC?

If the IP addresses of the instrument and the PC are correct, check to see whether the in­strument receives signals from the PC using the ping protocol.

Choose [Programs]-[Accessories]-[Command Prompt] from the Start menu.
When the cursor starts blinking, type [ping < IP address of the host you want to check

>].

If the IP address can be obtained from DNS by providing the host name, you can type in
the host name instead of the IP address.
For example, if the IP address of the instrument is 192.168.1.2, type [ping 192.168.1.2]
and press Enter. If the screen display is as shown below, the instrument and the PC are
communicating properly. "Time" represents how long it took for the instrument and the PC
to communicate.

Precautions on USB communication

To ensure safe transmission, disconnect all USB devices except the Memory HiLogger
from the PC before carrying out measurement with the Logger Utility.
Do not unplug the USB cable of the Memory HiLogger or switch off the power during mea­surement. Communication from the Logger Utility will be interrupted (this applies even to
loggers which are not measuring when multiple sets of Memory HiLoggers are connected).

Note) Communication may be interrupted, but the Memory HiLogger will continue to carry
out measurement.
If you have accidentally switched off the power to interrupt the communication, re-connect
the Memory HiLogger which cannot be communicated.

5.1 Registering Loggers in Logger Utility

5.1.3 Settings for Synchronized Measurement

If you use special 9683 Connection Cables, it is possible to measure with the
sampling of multiple loggers synchronized. You can set a master to be the refer­ence for sampling (base), and measure with up to five loggers synchronized.
With synchronized measurement, it is possible to perform measurement in which
a trigger is used among multiple loggers.

1. On the connection settings page, search and register or manually register

the loggers for measurement.

2. Add a check to [Synchronized Measurement] to enable synchronized mea-

surement.

A check cannot be added if only one logger is registered.

3. Set the logger to be the reference for sampling (master).

4. Click the [Test] button to display the synchronization test result.

• Always connect the 9683 Connection Cables when synchronized measure­ment will be performed. Furthermore, do not connect 9683 Connection Cables
if there are six or more loggers. The loggers will not work properly.

• Synchronized measurement is not possible with only one logger.

• The trigger setting is invalid when synchronized measurement is not per­formed.

5.2 Confirming the Unit Configuration
(Digital Filter Setting)

This section describes confirming the configuration of units attached to a logger
and setting the digital filter on the unit configuration page. When dual sampling is
set, also set the recording interval of each unit. If you set the digital filter, it is
possible to eliminate noise superimposed on an input signal. The longer the
recording interval is, the greater the effect of noise reduction. For the relation
between the recording interval and cutoff frequency, see "12.3.1 Model 8948
Voltage/Temp Unit" (p. 221) and "Recording Interval and Cutoff Frequency
Table" of "12.3.2 Model 8949 Universal Unit" (p. 223).

• If the digital filter is set to 50 Hz or 60 Hz, the scanning time of each channel
becomes almost as long as the time for obtaining all channel data within the
recording interval. If the digital filter setting is OFF, the scanning time becomes
approximately 10 ms.

• The digital filter is available for the measurement of voltage, temperature, and
humidity. It is not available for logic, pulse, and alarm channels.

When a Logger is Registered by Searching

When a logger is registered by searching on the connection settings page, the
instrument information is obtained automatically from the logger and then the
unit configuration is displayed.

that is long or has a large resistance is used, measurement errors may
occur. In such a case, use the thermocouple with burn out detection OFF
when taking measurements of high-accuracy.

Disables burn out detection. When the thermocouple is burn out, the
value is usually unstable or undecided.

Only when the recording interval falls within 100 ms to 1h, and the digital filter is
set at 50Hz/60Hz can the [Burn Out] be set to [ON].

When Humidity is Selected

Measurement is possible when an 8949 Universal Unit is connected and a 9701
Humidity Sensor is connected to the 8949 Universal Unit. The range is fixed to
100%f.s.

If humidity is selected for even one of the channels, the recording interval can
only be set to a setting longer than 5 seconds because the sensor response
speed is limited. If a recording interval of less than 5 seconds is selected, it is
automatically changed to 5 seconds.
