Memory Recorder to Replace Pen Recorders!
Continually record or analyze while comparing previous data
The 8720 VISUAL HiCORDER is designed specifically as an enhanced
replacement for pen recorders, based on popular user recommendations.
Functionality and appearance follow the highly regarded 8841 MEMORY
HiCORDER, while performance specifications emphasize long-term recording
and the capability to display previously recorded data on the screen. Operating
functions are designed to be simple, allowing easy use of the superb largecapacity memory. Those who have used pen recorders before will find this
recorder particularly attractive and easy to operate.

Possible only by recording in solidstate memory!
1. Ideal for mobile applications.
2. Screen display allows high-speed
analysis.
3. Waveforms can be compared with
previous data.
4. Data can be analyzed on a PC.
5. Solid-state memory eliminates

A LAN-Connectable Recorder!
Digitally Process Test Data
Have you ever noticed that although a pen recorder records
all test data on paper, only a certain portion of that data is
useful, so you end up scrolling through a lot of paper to find
that useful part?
With the 8720 VISUAL HiCORDER, test data can be
reviewed using the fast-scroll function on the large color
screen, so finding the important parts is easy.
All data is stored and managed electronically, and can be
output to a network printer using a LAN card and the 9333
LAN COMMUNICATOR software.

- Features Is reliability compromised in recording systems using MO or hard drive
data storage?
Disk storage devices such as MO or
hard disk drives are susceptible to
shock and vibration, and so are not
as ideal for automobile
measurement applications.
Because the 8720 stores data in
solid-state memory having no
moving parts, it is ideal for such
mobile measurements. The
memory has a battery backup,
so measurement data is
preserved even when power is
lost. The stored data is transferred
to magnetic media when
measurement is finished.
• Split-screen display shows current and
past data, with synchronized scrolling
function.
• Supports fast sampling even of distant
phenomena, while long-duration data
can be compressed to a convenient
size.
• Supports continuous X-Y recording
with unlimited recording time. Apply
input voltages for the horizontal and
vertical axes, and the X-Y locus is
drawn on the screen.
Data is stored in
solid-state
memory instead of
writing to an MO
or hard drive,
enabling reliable
measurement in
vibrating
environments,
such as a car.

temperature,
pressure, vibration,
etc.
Engine
2-way power supply system incorporating
battery operation and DC power adapter.
• Measurement data is displayed on the
screen and stored in memory without
using paper.
• Fast scroll function means being able
to capture any phenomena.
• Up to 16 analog channels with
isolated inputs.
• Seven types of input modules support
a wide variety of data collection
applications.
• Recorded data can be stored in CSV
format to be easily read on a PC.
Check previous events on split-screen display
• Recorded waveforms are backed up
even during power loss (for up to
three days when fully charged).
• Variable-level controls allow fine
adjustment of displayed waveform
size, and of course, scaling is fully
supported.
• Small size, low price with color LCD
and easy operation.

Analyze Digital Samples on a PC!
- Function Details Data Recording Principles
Isolated
Input voltage at each channel is
sampled* by an independent AD converter, which converts the
Memory
signal to a series of digital
values of instantaneous voltage.
The minimum and maximum
values of the many data samples
taken within the selected recording interval (e.g., 10
ms) are recorded in memory. One data-recording
element consists of a minimum/maximum pair of
values, and 100 of such pairs constitute the waveform
across one division of the time axis (for linear
Recording Speed
measurement). Therefore, even after a rapid change in
input voltage, the data quantities are compressed.

as maxima, minima and peak-to-peak waveform data
values can be detected and numerically displayed.

Remote Control via LAN Connection!
New standard for data transfer and remote control
Via a LAN connection, the screen of the 8720
VISUAL HiCORDER can be monitored in real time
on a PC running the 9333 LAN COMMUNICATOR
program. Additionally, the HiCORDER can be
operated remotely from the PC screen (requires 8720
version 2.00 or later).
● The measurement screen is duplicated on the PC screen via the
LAN.
● Measurement data from the 8720 can be copied from a LANequipped laboratory to a PC.
● Measurement waveforms can be printed on a network printer
via the LAN.
Support for Data Analysis on the PC
Recorded waveforms can be saved in CSV format to an
optional MO drive (128 to 640 MB), or the installed
floppy drive (720 KB, 1.2 and 1.44 MB) or a PC Card in
the standard slot provided (32 MB SRAM, or 528 MB
ATA hard drive). Besides the optional MO drive, an
external MO drive can be connected via the provided
SCSI interface. Data analysis can be performed using
common spreadsheet software.
Advantages of Ethernet and TCP/IP Connected Systems
● Data transfer speed is faster than MO write speed.
● Cable length may be up to 100 meters using 10Base-T.
● Data can be used immediately by an application program
on the PC (9333 LAN COMMUNICATOR).
● Less susceptible to errors compared with RS-232C
communications, and faulty data is automatically resent.
● Installation costs at the PC side are lower than GP-IB.
Disadvantages of Ethernet and TCP/IP Connected
Systems
● Transfer time depends on network usage, because the
network is shared with other LAN devices.
● Transfer time between other devices on the LAN may be
affected, depending on the amount of data transferred
from the recorder.

Large-Screen X-Y Recorder Functions Provided
Approx. Display
Applying input signals to both vertical and horizontal
axes generates an X-Y waveform that can be viewed on
the large screen and recorded. The same kinds of X-Y
recording are provided as have been previously
available, but without requiring any paper.
Scaling Functions
Actual measurements usually involve parameters other
than voltage. Various physical parameters such as speed,
vibration and temperature commonly need to be
recorded, and this signal data should be directly readable,
without having to be manually converted. In such
measurement conditions, the scaling function can be
used to automatically convert to the desired parameter
value. Additionally, waveform amplitude can be adjusted
using the Variable Gain function.
In addition, if accurate input voltage amplitude
measurement is not required, the amplitude can be
intentionally modified with the Vernier Adjustment
function.
