Measurement categories (Overvoltage categories)
This instrument complies with CAT I safety requirements.
To ensure safe operation of measurement instruments, IEC 61010 establishes
safety standards for various electrical environments, categorized as CAT I to
CAT IV, and called measurement categories. These are defined as follows.
Higher-numbered categories correspond to electrical environments with
greater momentary energy. So a measurement device designed for CAT III
environments can endure greater momentary energy than a device designed
for CAT II.
Using a measurement instrument in an environment designated with a
higher-numbered category than that for which the instrument is rated could
result in a severe accident, and must be carefully avoided.

Handling the CD-R
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 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.

1.1 Major Features
______________________________________________________________________________________________
1.1 Major Features
(1) Waveform Comparison Function
The 8730-10, 8731-10 Waveform Comparator are designed specifically to
compare waveforms, which is a function of our MEMORY HiCORDERs.
The 8730-10 is the one-channel model; the 8731-10 is the two-channel
model.
Two methods of comparison are available: Area Comparison (which uses a
comparison area created for the waveform), and Value Comparison (which
uses upper and lower limits). Both methods can be used simultaneously.
In Area Comparison, separate areas can be used for CH1 and CH2, with
independent comparison possible. (This is only available with the 8731-
10.)
Value Comparison is based on the result of value calculation (e.g.,
maximum, minimum, or average value).
(2) Forms of Installation
Both 8730-10, 8731-10 models have handles and rubber feet. The units
are portable and can be installed on a workbench or shelf.
The handles and rubber feet are easily secured with screws and can be
easily removed. The 8730-10, 8731-10 can be assembled on a rack
(compliant with JIS or EIA standard) or a panel. A custom-made
mounting bracket is optionally available. Please contact your vendor or
our agent for details.
(3) High-Speed Sampling
The 8730-10 records the waveform of one channel and the 8731-10
records the waveforms of two channels simultaneously at a maximum
speed of 1MS/s.
Given the high-speed sampling of 1,000,000 times per second, even an
instantaneous change in input signal is not missed.
(4) Saving Data
Not only waveform comparison, but also waveform data can be saved on a
PC card.
Data is saved in binary format for reading with the 8730-10, 8731-10, in
CSV format for reading with a PC, or in BMP format for screen images.
Comparison area and waveform data (up to 500DIV when using the 8936)
saved on the 8835-01 can be read with the 8730-10, 8731-10.
(5) Color LCD
A 7.2-inch (640 x480 dots) STN color LCD is used. The waveforms of
CH1 and CH2, or a waveform and its comparison area are clearly
distinguished.
The screen background is blue when comparison is not being conducted.
The background changes to green when the comparison result is PASS or
red when the result is FAIL.

(6) Data Display
A gauge (for graduations) or an individual comparison result is displayed
at the left of the screen.
Comments are shown at the top of the screen.
(7) Interface
The 8730-10, 8731-10 is equipped with LAN (10BASE-T) and RS-232C
interfaces.
The 9333 LAN COMMUNICATOR enables data transfers and remote
control.
(8) External Control Terminals
The external control terminals are used to output comparison results
(PASS or FAIL) and to control the 8730-10, 8731-10.
The external control terminals are insulated from the power supply and
GND of the 8730-10, 8731-10.
Value comparison and area comparison results are output from different
terminals. (The 8731-10 compares data for CH1 and CH2 separately, then
outputs the results separately.)
(9) Dust-proof Structure
Flat sheet keys eliminate gaps where dust can gather.
The front panel has a simplified dust-proof structure. The PC card slot has
acover.
