We define measurement tolerances in terms of f.s. (full scale) values, with the
following meanings:
f.s. (maximum display value or scale length)
The maximum displayable value or scale length. In this instrument, the maximum displayable value is the range (V/div) times the number of divisions (20) on
the vertical axis.
Example: For the 1 V/div range, f.s. = 20 V

Measurement categories
To ensure safe operation of measurement instruments, IEC 61010 establishes
safety standards for various electrical environments, categorized as CAT II to
CAT IV, and called measurement categories.
CAT II Primary electrical cir-
CAT III Primary electrical circuits of heavy equipment (fixed installations) con-
CAT IV The circuit from the service drop to the service entrance, and to the
Using a measurement instrument in an environment designated with a highernumbered category than that for which the instrument is rated could result in a
severe accident, and must be carefully avoided.
Use of a measurement instrument that is not CAT-rated in CAT II to CAT IV
measurement applications could result in a severe accident, and must be carefully avoided.

Operating Precautions
Operating Precautions
Follow these precautions to ensure safe operation and to obtain the full benefits of the various functions.
Before Use
Before using the instrument the first time, verify that it operates normally to
ensure that the no damage occurred during storage or shipping. If you find any
damage, contact your dealer or Hioki representative.
Before using the instrument, make sure that the insulation on the connection
cords and connection cords is undamaged and that no bare conductors are
improperly exposed. Using the instrument in such conditions could cause an
electric shock, so contact your dealer or Hioki representative for replacements.
Instrument Installation
Operating temperature and humidity: -10 to 40°C, 20 to 80%RH (non-condensating)
When printing: 0 to 40°C, 20 to 80%RH (non-condensating)
When using a hard disk: 5 to 40°C, 20 to 80%RH (non-condensating)
Temperature and humidity range for guaranteed accuracy: 23 ± 5°C, 20 to
80%RH (non-condensating)
Avoid the following locations that could cause an accident or damage to the
instrument.
Exposed to direct
sunlight
Exposed to high temperature
Exposed to water, oil,
other chemicals, or
solvents. Exposed to
high humidity or condensation
Exposed to high levels of particulate dust
In the presence of corrosive or explosive
gases
Exposed to strong
electromagnetic fields
Near electromagnetic
radiators
Subject to vibration
Installing
To prevent overheating, be sure to leave the specified clearances around the unit.
• The instrument should be operated only with the bottom or rear side downwards.
• Vents must not be obstructed.
• Do not install the instrument at a slanted angle.
Handling the Instrument
To avoid electric shock, do not remove the instrument's case. The internal components of the instrument carry high voltages and may become very hot during
operation.
Never modify the instrument. Only Hioki service engineers should disassemble
or repair the instrument. Failure to observe these precautions may result in fire,
electric shock, or injury.
• To avoid damage to the instrument, protect it from physical shock when transporting and handling. Be especially careful to avoid physical shock from dropping.
• Before transporting the instrument, disconnect all cables and remove any CF
card, USB memory stick and recording paper.

Handling the CD
This instrument may cause interference if used in residential areas. Such use
must be avoided unless the user takes specia l measures to reduce e lectromagnetic emissions to prevent interfe rence to the reception of radio and television
broadcasts.
• Avoid stepping on or pinching cor ds, which cou ld dam age the pr obe insu lation.
• To avoid breaking the cords, do not bend or pull them.
Use only the specified connection cords. Using a non-specified cable may result
in incorrect measurements due to poor conne ction or other reasons.
• Always hold the disc by the edges, so as not to make fingerprints on the disc or
scratch the printing.
• 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 hi gh
temperature or humidity, as there is a danger of warping, with consequent loss
of data.
• To remove dirt, dust, or fingerprints from th e disc , wipe w ith a dry clot h, or u se
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 PC system that arises
from the use of this CD, or for any problem related to the purchase of a Hioki
product.

Sturdy finish and convenient
carrying handle
Easily take the unit anywhere.
Easy loading of recording paper
High-speed printing
One-touch insertion allows quick and trouble-fre e
operation.
Immediately ready for measurement after power-on *
Logic modules allow
measurement in 64 channels
Ideal for multi-point measurements.
High-speed sampling: 20 Ms/s
Enables responsive evaluation and analysis.
* For best measurement precision, a warm-up
period of about 30 minutes after power-on is
recommended, to allow the internal temperature of the input modules to stabilize.
Then perform zero-adjust and start the measurement.

1.4 Basic Key Operations
1.4.2 Using a Mouse to Perform Key Operations
You can use a commercially available USB mouse to perform the same operations as with the keys
on the MR8847.
• There are a variety of mice available, and not all devices will work with the
instrument. If you find that your mouse isn't working properly, try a different
model.
• The instrument's USB ports are designed exclusively for use with mice and
USB memory sticks. Do not connect any other type of device.
• When operating the instrument with the mouse, some screens may not display properly.
• When using a mouse, do not change the interface on the System screen to
anything other than "LAN." You may not be able to use the mous e while USB
communications are in progress.
• External interference may cause the mouse to malfunction. Keep the mouse
and mouse cable as far away as possible from sources of interference.
The following diagram describes how to operate the instrument with a mouse:

2.1 Install an input module
2.1 Install an input module
Input modules specified at the time the instrument is ordered are supplied preinstalled. Use the following procedures to add or replace input modules, or to remove them from the instrument.
Preparations
• To avoid electric shock accident, before removing or replacing an input mod-
ule, confirm that the instrument is turned off and that the connection cords are
disconnected.
• The mounting screws must be firmly tightened or the input module may not
perform to specifications, or may even fail.
When an input module is not used
• To avoid the danger of electric shock, never operate the instrument with an
input module removed. To use the instrument after removing an input module,
install a blank panel over the opening of the removed module.
• To avoid damaging input modules, do not touch the input module connectors
on this instrument.
• Measurements made without a blank p anel inst alled may fail to meet specifica-
tions because of temperature instability within the instrument.
For information on analog channel accuracy when using logic channels, see
"8.10 Making Detailed Settings for Input Modules" ( p.146).
