Fast 10-ms Sampling
Up to 600 Channels Data Logging
MEMORY HiLOGGER Model 8423 is a data acquisition system capable of
measuring and recording multiple channels at high speed. Acquired data can
be easily analyzed on a personal computer. This model is ideal for acquiring
data for evaluation and testing at development sites. If your evaluation
needs require faster data sampling than was available with former HIOKI
MEMORY HiLOGGERs, or if you just need more measurement channels,
this model has the capabilities you want.

Who needs 10 ms high-speed sampling?
- Answer -
To acquire data when converting automobile
electronics for electric or hybrid vehicles
● Fastest measurement interval (sampling interval) is 10 ms
● Acquires up to 600 channels of data with 10 ms sampling interval
● Insulation withstand voltage between the measurement channels in each module is 200 V
(Model 8948)
In the development of electric and hybrid automobiles, the
need to capture sudden swings in various loads requires
a measurement instrument with multi-channel highspeed sampling capability. For this purpose, HIOKI has
developed a very economical logger that can measure with
Sudden-load-change testing of a fuel cell employs dual sampling to
measure with 10-ms (upper trace) and 100-ms sampling (lower trace).
(Timebase: 50 ms/div).
10-ms sampling interval on all channels. Also included is
a dual-sampling function that can measure at two different
sampling rates simultaneously. This new model can follow
waveforms that former 100-ms-sampling instruments could
not.
A 5-Hz pulse waveform is measured using dual sampling: 10-ms
(upper trace) and 100-ms sampling (lower trace)
(Timebase: 50 ms/div).
3
Who needs 120 or 600 channels?
- Answer -
To acquire multi-point temperature distribution data
To measure the voltage of each cell in a stack
● Expandable up to 120 channels with a single instrument
● Up to five instruments can be connected for measuring up to 600 channels
● Isolated to sustain up to 600 V between modules and earth
Temperature distribution is measured to evaluate air
conditioning systems during development. A system to
acquire data on up to 600 channels can be constructed
with merely a LAN or USB connection, providing highly
detailed temperature distribution measurements.
With all channels isolated and a 600V AC/DC maximum
rated voltage to earth, even when the common mode voltage
increases as is common with layered batteries, the voltage
of each individual battery cell can be safely measured.

“Simplicity” as a Design Concept
Installation
Easily add input modules: just align and mate the connectors
on the left side of the instrument assembly, and turn
the metal clasp. For added strength, attach the supplied
mounting bracket on the rear, or attach a standard DIN rail
to the rear for tray or rack mounting.
Because the terminal blocks are designed to be removable,
thermocouples can be connected to the terminal block in
hand before connecting the block to a HiLOGGER input
module, with just one touch.
Each measurement module daisy-chains
onto the stacking configuration.
Mounting with a standard DIN rail is supported.
Measurement configuration settings
Logger configuration settings are made from a computer
running the supplied application program. Settings can be
easily made using familiar PC operations. To keep the process
simple, the user is guided sequentially through the setting items.

Post-measurement analysis (New Double-Thumb function*)
The newly developed Double-Thumb function simplifies analysis.
Two windows are displayed side by side, each with a scroll bar at the
bottom containing a thumb (scroll box) that corresponds to the length
and position of that window’s displayed segment within the overall

Real-time saving to CF Card
Each measurement can be saved to a CF Card in real time.
Continuous long-term recording can be performed with
high capacity CF Cards up to 1 GB. Data can be viewed
on a PC using the supplied Logger Utility program.

This exclusive technology has been developed to preserve data as reliably
as possible in the event of a power failure, by incorporating memory card
technology with the know-how built into the MEMORY HiLOGGER
8420 -50, 8421-50 and 8422-50 series. The 8423 emphasizes the existing
HiLOGGER functions and maintains internal supply voltage with a
large internal capacitor until all data
has been saved to the ca rd, resulting
in greater reliability when acqui r ing
large amounts of data.

Two different measurement intervals can be specified
at the same time (one interval setting per input module).
Using dual sampling, the appropriate measurement
interval can be set for each type of object to be measured,
optimizing use of internal memory and CF Card capacity.

Enhanced PC Interface
USB Port Included
A USB 2.0 (mini-B connector) port is included as standard. The
8423 instrument and a PC can be connected by a USB cable (A
to mini-B) for transferring 8423 operating settings and data.
LAN Terminal Included
A 100Base-TX LAN terminal is included as standard. The
8423 instrument and a PC can be connected by a LAN cable
for transferring 8423 operating settings and data.
External Control Inputs Included
Input terminals are provided for external triggering, external start and stop
and external sampling. External signals can be applied as a trigger source
and to start and stop measurements, so data can be acquired by controlled
sampling timing.
Note: External triggering and external sampling share a common terminal, so only one of these control input types can be
used at a time.

More Functional Details
All-Channel Synchronous Measurement Capability
When measuring up to 120 channels on combined modules,
all input channels are sampled synchronously. When multiple
8423s are connected via LAN or USB for measuring up to 600
channels, the sampling of each instrument in the system can be
synchronized using optional Connection Cable Model 9683.
As well as PC-based data collection, measurement start and
stop can be controlled by the [START/MARK] and [STOP]
keys on a master 8423.
Note: Any 8423 may be designated as the master. Only the initial acquisition criteria setting needs to
be performed on a PC via USB or LAN.
Enhanced Noise Immunity
A delta-sigma type A/D converter has been incorporated
in the measurement circuitry. The effects of previously
problematic inverter switching noise and 50/60 Hz hum
noise have been greatly reduced by the digital filtering
function using the oversampling principle inherent in this
type of device.
Note: Optimum noise suppression is obtained with recording intervals of two seconds or
longer
