Atec Hioki-8847 User Manual
For the fi eld
Professional
■ Isolated inputs for all channels enhance measurement safety
by letting you record differing electric potential objects simultaneously
■
Sturdy construction designed for use in the fi eld
Tough body and strong enclosure provide superior resistance to shocks, falls, and
vibrations. Clears a 50 cm drop test.
Note: Using in-house testing conditions. Absence of impairment or
damage in all cases is not assured.
■ High-speed printing for checking data right on the spot
Printer features newly designed roll paper drop-in loading and one-touch setup, along
with high 50 mm/s printing speed.
■
Ergonomic controls for superior user convenience
Large key tops are easy to operate and feature surface coating so you can simply wipe
off grease stains and other residue.

■ A problem occurs, requiring immediate attention on site
Grab the sturdy handle and go. The tough construction can
take a few knocks.
■ Start measurement without reading through the manual
The Help Wizard assists you to do exactly what you want.
■ Print out results on the spot
Load printer paper with a simple one-touch operation.
High printing speed gives you a hard copy in a snap.
High Speed
■ High-speed sampling up to 20 MS/s
Full isolation for all channels and simultaneous sampling
■ Store data on media three times faster
To 30 MB CF Card: Max. 40 seconds
(8841: approx. 110 seconds)
Data save speed may vary, depending on conditions.
X-Y
Operation
■ Multi-channel X-Y recorder with electronic data log
■ Simultaneous recording over 16 analog + 16 logic channels
■ Simultaneous recording over 64 logic + 10 analog channels
Plug-in modules provide the flexibility to match most
channel and signal confi guration requirements.
Computer
Integration
■ Easy storage of recorded data
USB memory stick / CF card / internal hard disk
■ HTTP/FTP server function and remote operation capability
provide easy access to data

One-touch design takes the hassle out of the process. 50mm/sec print speed
Start a measurement
without delay
No more need for cumbersome and time-consuming steps such
as threading the paper between rubber rollers and the thermal
print head. Simply drop the paper roll in place, pull the tip out
slightly, and close the door. As easy as one, two, three.

Actual size of printout example
■ Print a complete A4 format report on site
If the customer requires a report, the 8847 can deliver
without delay. The A4 format printout shows waveforms
with high resolution. Even minute details and changes
can be detected easily, and measurement parameters used
for obtaining the data are also printed. Even in the age of
electronic communication, being able to produce a paper
document on the spot can be very effective and result in
enhanced credibility.
■ Hard copy of the display screen, then and there
Observed waveforms, setup pa rameters,
processing values, AB cursor readouts
and more--a simple push of a button and
the hi gh-speed ther mal printer g ives
you a hard co py of the en tire scre en
contents. Saving as a BMP file on a CF
card or USB memory is also possible.
Printing is tw ice a s fas t compa red t o the performanc e o f
previous HIOKI products. No more waiting when printing out
data on site to give to the customer.
"The customer needs measurement results in hand right away!"
50 mm/s printing speed produces results in a flash
No Problem!
"Changing paper is a hassle, and printing speed should be faster!"

Making input ampli tude and
trigger settings becomes much
easier when the effect can be
observed immediately. Setting
va lue s can be su perimpo sed
on the wa v e f o rm d i spla y to
maximize the waveform area,
or you can separate the display
areas to enhance the legibility
of setting items.
"Making settings is too complicated if I can't see the waveform!"
Make settings on screen while watching the waveform.
No Problem!

Monitor high-speed
signals
High-speed 20 MS/s sampling provides ample margin
The operation principle is the same as for a digital oscilloscope: data are stored at
high speed in the high-capacity internal memory. Even with all channels operating
simultaneously, sampling rates up to 20 megasamples per second (50 ns cycle) are
possible. This ensures that sudden event spikes and instantaneous waveform changes
are captured reliably.
■ Semiconductor memory storage
Units using hard disks or other mechanical media for storage are vulnerable to
vibrations and therefore are not ideal for automotive measurement and similar
applications. By saving data in semiconductor based memory without any mechanical
drive parts, the Memory HiCorder is much more suited to such applications. Simply
back up the data later to CF card or USB memory, and you're done.
