Accuracy
The instrument accuracy is expressed by dening a percentage of the setting.
Setting Indicates the voltage, current, or other value that the instrument has been
congured to output. Limit values for setting errors are expressed as a

Measurement categories
To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards
for various electrical environments, categorized as CAT II to CAT IV, and called measurement
categories.
DANGER
• Using a measuring 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.
• Using a measuring instrument without categories in an environment designated
with the CAT II to CAT IV category could result in a severe accident, and must
be carefully avoided.
CAT II: When directly measuring the electrical outlet receptacles of the primary electrical
circuits in equipment connected to an AC electrical outlet by a power cord (portable
tools, household appliances, etc.).
CAT III: When measuring the primary electrical circuits of heavy equipment (xed installations)
connected directly to the distribution panel, and feeders from the distribution panel to
outlets.
CAT IV: When measuring the circuit from the service drop to the service entrance, and to the
power meter and primary overcurrent protection device (distribution panel).

Operating Precautions
Check before use
Use of the devices should conrm not only to their specications, but also to the specications of all
options and other equipment in use.
DANGER
If the connecting cable or the module is damaged, there is a risk of electric shock.
Before using the module perform the following inspection.
• Before using the module, make sure that the insulation on the cables are
undamaged and that no bare conductors are improperly exposed. If there is any
damage on the cable, replace it with those specied by our company.
• Before using the module for the rst time, verify that it operates normally to
ensure that no damage occurred during storage or shipping. If you nd any
damage, contact your authorized Hioki distributor or reseller.
Module installation
WARNING
Installing the module in inappropriate locations may cause a malfunction of
module or may give rise to an accident. Avoid the following locations.
• Exposed to direct sunlight or high temperature
• Exposed to corrosive or combustible gases
• Exposed to a strong electromagnetic eld or electrostatic charge
• Near induction heating systems (such as high-frequency induction heating
systems and IH cooking equipment)
• Susceptible to vibration
• Exposed to water, oil, chemicals, or solvents
• Exposed to high humidity or condensation
• Exposed to high quantities of dust particles

Operating Precautions
HIOKI U8793A981-05
Handling of the module
• Do not exceed the module or cable ratings or specications range.
• To avoid electric shock, do not remove the module's case.
The internal components of the module carry high voltages and may become
very hot during operation.
• To avoid electric shock accident, before removing or replacing the module,
conrm that the Memory HiCorder is turned off and that the connection cables
are disconnected.
• To avoid the danger of electric shock, never operate the Memory HiCorder
with the module removed. Install a blank panel in the Memory HiCorder after
removing the module.
• To avoid damage to the module or electric shock accident, use original screws
from the factory shipment for fastening the module.
If any of the screws is lost or there is any damage on the module, contact your
authorized Hioki distributor or reseller.
DANGER
WARNING
CAUTION
• To avoid damage to the module, do not touch the connectors to be inserted into the
Memory HiCorder.
• Do not perform measurements when the blank panel of the Memory HiCorder has
been removed. This condition will cause unstable temperature in the module and
does will not satisfy the specications.
• To avoid damage to the module, protect it from physical shock when transporting and
handling. Be especially careful to avoid physical shock from dropping.
• The mounting screws must be rmly tightened or the module may not perform to
specications, or may even fail.
This module may cause interference if used in residential areas. Such use must be avoided
unless the user takes special measures to reduce electromagnetic emissions to prevent
interference to the reception of radio and television broadcasts.
Precautions during transportation
Store the packaging in which the module was delivered, as you will need it when transporting the
module.

HIOKI U8793A981-05
Overview
1.1 Features
The U8793, MR8790, and MR8791 are Memory HiCorder modules designed to output basic
waveforms such as sine waves and rectangular waves, user-created waveforms, logic patterns,
and other signals. (Models vary by the type of waveform they can output.) Since a single Memory
HiCorder can accommodate the U8793, MR8790, or MR8791 along with one or more measurement
modules, it is possible to both measure and generate waveforms with one instrument.
U8793 Arbitrary Waveform Generator Unit
Each module provides two channels of output. Since output channels
Isolated-channel
output
Maximum output
voltage of 15 V
Channel synchronization
Sweep functionality
are isolated from the host Memory HiCorder’s chassis as well as from
each other, the instrument can be connected to other devices that
operate at a different potential. (The maximum rated terminal-to-ground
voltage is limited to 30 V AC RMS or 60 V DC.)
The module can output up to 15 V. This capability eliminates the need to
connect the module’s output to an external amplier prior to simulating
a signal from an automotive sensor or other device, enabling output
signals to be applied directly.
Phase can be set between channels on the same module and between
channels on different modules.
Sweep functionality is provided for frequency, amplitude, offset, and
duty cycle (pulse waves only).
Overview
Program function
Observed
waveform output
Users can set an output waveform type, generation duration, and the
iteration count for the loop for each step.
The module can load waveform data measured by the Memory
HiCorder and then output a waveform that is identical to the observed
waveform, enabling use in applications such as reproduction testing.
MR8790 Waveform Generator Unit
Each module provides four channels of output. Since output channels are
Isolated-channel
output
High-precision
DC output
isolated from the host Memory HiCorder’s chassis as well as from each
other, the instrument can be connected to other devices that operate at
a different potential. (The maximum rated terminal-to-ground voltage is
limited to 30 V AC RMS or 60 V DC.)
Thanks to its ability to generate high-precision DC output with an output
accuracy of ±0.6 mV, the MR8790 can generate output simulating the
minuscule voltage variations of sensor output.
MR8791 Pulse Generator Unit
Each module provides eight channels of output. Output channels are
Multichannel
output
isolated from the host Memory HiCorder’s chassis. (Output channels
are not isolated from each other.) (The maximum rated terminal-toground voltage is limited to 30 V AC RMS or 60 V DC.)
Wide selection
of output modes
Depending on the conguration, each channel can generate
independent pulse output, or all channels can generate synchronized
pattern output. In addition, users can select either TTL level logic output
or open-collector output as the output type (for each channel).
