Thank you for purchasing the HIOKI Model MR8880-20 Memory HiCorder. To obtain
maximum performance from the instrument, please read this manual first, and keep
it handy for future reference.
The inputs of the instrument are specifically for voltage input.
An optional clamp-on probe is required for current measurement with the Memory
HiCorder. In this manual, all models of these probes are collectively referred to as
"clamp sensors." For details, refer to the instruction manual of the particular clamp
sensor to be used.

Safety Information

Accuracy
We define measurement tolerances in terms of f.s. (full scale), rdg. (reading) and
dgt. (digit) values, with the following meanings:
Measurement categories
This instrument complies with CAT IV (300 V AC/DC), CAT III (600 V AC/DC) safety
requirements.
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.
Using a measurement instru-
ment in an environment desig-
nated with a higher-numbered
category than that for which the
instrument is rated could result
in a severe accident, and must
be carefully avoided.
Use of a measurement instru-
ment that is not CAT-rated in
CAT II to CAT IV measurement
applications could result in a
severe accident, and must be carefully avoided.
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 divi-
sions (10) on the vertical axis. Example: For the 1 V/div range, f.s. = 10 V
rdg. (reading or displayed value)
The value currently being measured and indicated on the measuring instru-
ment.
dgt. (resolution)
The smallest displayable unit on a digital measuring instrument, i.e., the
input value that causes the digital display to show a "1" as the least-signifi-
cant digit.
CAT II Primary electrical circuits in equipment connected to an AC electrical outlet by a
power cord (portable tools, household appliances, etc.) CAT II covers directly
measuring electrical outlet receptacles.
CAT III Primary electrical circuits of heavy equipment (fixed installations) connected
directly to the distribution panel, and feeders from the distribution panel to out-
lets.
CAT IV The circuit from the service drop to the service entrance, and to the power meter
and primary overcurrent protection device (distribution panel).

Operating Precautions
8
Follow these precautions to ensure safe operation and to obtain the full benefits of
the various functions.
Before using the instrument the first time, verify that it operates normally to ensure
that no damage occurred during storage or shipping. If you find any damage, contact
your dealer or Hioki representative.
Operating temperature and humidity
Temperature: -10°C to 50°C (14 to 122°F),
Humidity: -10°C to 40°C (14 to 104°F) at 80%RH or less (non-condensating)
40°C to 45°C (104 to 113°F) at 60%RH or less (non-condensating)
45°C to 50°C (113 to 122°F) at 50%RH or less (non-condensating)
• During battery operation: 0°C to 40°C (32 to 104°F) at 80% RH or less (non-con-
densating)
• During battery charging: 10°C to 40°C (50 to 104°F) at 80% RH or less (non-con-
densating)
Temperature and humidity range for guaranteed accuracy: 23±5°C (73±9°F),
80%RH or less (non-condensating)
Operating Precautions
Before Use
Before using the instrument, make sure that the insulation on the
probes, connection cords, and clamp sensor leads 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 Precautions
9
Avoid the following locations that could cause an accident or damage to the
instrument.
Exposed to direct sunlight
Exposed to high temperature
In the presence of corro-
sive or explosive gases
Exposed to water, oil, other
chemicals, or solvents
Exposed to high humidity or
condensation
Exposed to strong electro-
magnetic fields
Near electromagnetic radi-
ators
Exposed to high levels of
particulate dust
Near induction heating sys-
tems (e.g., high-frequency
induction heating systems
and IH cooking utensils)
Subject to vibration
Handling the Instrument
• Do not allow the instrument to get wet, and do not take measure-
ments with wet hands. This may cause an electric shock.
• 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.
• Do not attempt to modify, disassemble or repair the instrument;
as fire, electric shock and injury could result.
• Avoid obstructing the ventilation holes on the sides of the instru-
ment, as it could overheat and be damaged, or cause a fire.

Operating Precautions
10
• The operating temperature range of the instrument is -10°C to 50°C.
Do not use the instrument in an environment that is out of this range.
• To avoid damage to the instrument, protect it from physical shock
when transporting and handling. Be especially careful to avoid physi-
cal shock from dropping.
• This instrument 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.
• Before transporting the instrument, disconnect all cables and remove
any CFcard, USB flash drive and recording paper.
• Do not slant the device or place it on top of an uneven surface. Dropping
or knocking down the device can cause injury or damage to the device.
• The instrument is equipped with a protector. The physical shock pro-
tection provided by the protector does not fully prevent instrument fail-
ures. Be sufficiently careful when handling the instrument.
Correct measurement may be impossible in the presence of strong
magnetic fields, such as near transformers and high-current conduc-
tors, or in the presence of strong electromagnetic fields such as near
radio transmitters.
Handling the Cords and Cables
To avoid electric shock, do not exceed the lower of the ratings
shown on the instrument and test leads
• Avoid stepping on or pinching cables, which could damage the cable
insulation.
• To avoid breaking the cables, do not bend or pull them.
• To avoid damaging the power cord, grasp the plug, not the cord, when
unplugging it from the power outlet.
• When disconnecting the BNC connector, be sure to release the lock
before pulling off the connector. Forcibly pulling the connector without
releasing the lock, or pulling on the cable, can damage the connector.
• To prevent an electric shock accident, confirm that the white or red
portion (insulation layer) inside the cable is not exposed. If a color
inside the cable is exposed, do not use the cable.
