The MR8870-20 offers two modes: mem
RMS recorder mode. This manual primarily describes operation of
the instrument in memory recorder mode. For more information
about RMS recorder mode, see the included Measurement Guide
(RMS Recorder).
An optional clamp-on probe is required for current measurement
w
ith 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.

Accuracy
We define measurement tolerances in terms of f.s. (full scale), rdg. (reading) and
dgt. (digit) 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
layable value is the range (V/div) times the number of divisions (10) on the verti-
disp
cal 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 instrument.
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-significant digit.
Safety Information
Measurement categories
This instrument complies with CAT II 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.

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 en
or shipping. If you find any damage, contact your dealer or Hioki
representative.
• Before using the instrument, make sure that the insulation on the
pro
bes, connection cords, and clamp sensor leads is undamaged and that no bare conductors are improperly exposed. Using
the instrumen
so contact your dealer or Hioki representative for replacements.

The maximum operating (ambient) temperature for the MR8870-20
is 40°C. Do not attempt to use in higher temperature environme nts.
Correct measurement may be impossible in the presence of
strong magnetic fields, such as near transformers and high-cur
rent conductors, or in the presence of strong electromagnetic
fields such as near radio transmitters.
Installation Precautions
• Do not install the instrument with any side except the bottom facing down.
• Leave sufficient space around the ventilation holes and install the
instrumen
Handling the Instrument
• Do not allow the instrument to get wet, and do not take measurements with wet hands. This may cause an electric
shock
.
• Do not attempt to modify, disasse
ment; as fire, electric shock and injury could result.
• To avoid damage to the instrument, protect it from physical
shock when transporting and handling. Be especially careful to
avoid physical shock from dropping.
• This i nstrument may cause interference if used in residential
are
as. 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.

Operating Precautions
• To prevent an electric shock accident, confirm that the white or
red portion (insulation layer) inside the cable is not exp osed. If a
color inside the cable is exposed, do not use the cable.
• Use only the specified measurement cables. Using a non-specified cable may result in incorrect measurements due to poor connection or other reasons.
• Before using a clamp sensor or logic probe, read the instruction
manual supplied with it.
Before Turning Power On
Using the Battery Pack
• For battery operation, use only the HIOKI Model 9780 Battery
Pack. We do not take any responsibility for accidents or
amage related to the use of any other batteries.
d
See: "2.1 Using the Battery Pack (Option)" (p. 24)
Using the AC Adapter
• Use only the supplied Model Z1005 AC Adapter. AC adapter
input voltage range is 100 to 240 VAC (with ±10% stability) at
50/60 Hz. To avoid electrical hazards and damage to the
instrument, do not apply voltage outside of this range.
• Turn the instrument off before connecting the AC

Operating Precautions
Connect the clamp-on sensors or measurement cables to the
instrument first, and then to the active lines to be measured.
Observe the following to avoid electric shock and short circuits.
• To avoid short circuits and potentia
ards, never attach the clamp to a c
more than the maximum rated voltage to earth, or over bare
conductors.
• Do not allow the connection cord clip

• When the clamp sensor is opened, do not allow the metal
art of the clamp to touch any exposed metal, or to short
p
between two lines, and do not use over bare conductors.
• Do not leave the Memory HiCorder connected to test object
in environments where a voltage surge might exceed the
dielectric withstand voltage. Doing so could result in damage to the Memory HiCorder, bodily injury or fatal accident.
CD Handling
• Always hold the disc by the edges, so as not to make fingerprints
on the disc or scratch the printing.
• Never touch the recorde d side of the disc. Do not place the disc

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 temp
of warping, with consequent loss of data.
• To remove dirt, dust, or fingerprints from the disc, wipe with a dry
