Operation Precautions
Handling the Printer and Recording Paper
WARNING
The print head and surrounding metal parts can become hot. Be careful to avoid
touching these parts.
CAUTION
Be careful not to cut yourself with the paper cutter.
• Please use only the specied recording paper. Using non-specied paper may not only result in
faulty printing, but printing may become impossible.
• If the recording paper is skewed on the roller, paper jams may result.
• Always use the paper cutter to cut the printed paper. Excessive paper dust can accumulate on the roller
if the paper is cut by the print head, which may result in paper jams or white streaks in the printing.
Storing Data Recordings
The recording paper is thermally and chemically sensitized. Observe the following precautions to
avoid paper discoloration and fading.
• To avoid discoloration, do not expose it to direct sunlight. Store below 40°C (104°F) and 90% RH.
• Store away from dew and damp places.
• Make photocopies of recording printouts that are to be handled or stored for legal purposes.
• If the thermal paper is exposed to an organic solvent such as alcohol or ketone, it may no longer
develop properly, and recorded data may fade. Pressure sensitive tapes such as exible PVC
lms and scotch tapes must be handled with care as they contain organic solvents.
• Also, the thermal recording paper is ruined by contact with wet Daizo copy paper.
Avoid exposure to direct
sunlight.
Do not store thermal paper
above 40°C and 90% RH.
Avoid stacking with wet
Diazo copy paper.
Avoid exposure to volatile
organic solvents like
alcohol, ethers, and
ketones.
Avoid contact with
adhesive tapes like
soft vinyl chloride and
cellophane tape.
Storing Recording Paper
• Store thermal paper where its temperature will not exceed 40°C (104°F).
• The paper will deteriorate if exposed to light for a long time, so do not remove rolls from their
wrappers until ready to use.Handling Media

• With some external media, the instrument may not start up if power is turned on while the external
media is inserted. In such a case, turn power on rst, and then insert the external media. Prior
testing is recommended.
• Unusual USB ash drives, such as those that require ngerprint authentication or a password,
cannot be used.
• When saving or loading data, insert the storage media before selecting it. If the media is not
inserted, the le list display will not appear.
• All media (built-in drive, USB memory stick and CF card) have a limited service life. After
extensive use over a long period, data retention and readout may become stop working. In
such cases, you should procure new media.
• The built-in drive (SSD) is a consumable part. When the written data reaches the capacity (about
60 TB), no more data can be recorded. In such a case, the SSD should be replaced with a new
one.
• When the instrument is turned off for a long time (more than one year), the data stored on the
built-in drive (SSD) may be lost. Be sure to back up the data if the instrument is left turned off
for a long time.
• Automatic saving of data is possible only on built-in drive (SSD), USB memory stick and CF
card media.
• Data can also be saved to a USB ash drive in real time, but for data protection we recommend
using Hioki’s optional CF card instead.

Operation Precautions
Before Connecting Cables
When measuring power line voltage
• Connecting cables should only be connected to the secondary side of a breaker
Even if there is a short circuit on the secondary side of the breaker, the breaker
cuts off the electric supply. Do not connect to the primary side of a breaker
because unrestricted current ow could damage the instrument and facilities if
a short circuit occurs.
• To prevent electrical shocks and personal injury, do not touch any input
terminals on the VT (PT), CT or the instrument when they are in operation.
• Do not permanently connect the instrument in an environment where voltage
surges exceeding the maximum input voltage may occur. Failure to observe
this precaution could result in damage to the instrument or personal injury.
• Do not short-circuit two wires to be measured by bringing the connection cables
into contact with them. Arcs or such grave accidents are likely to occur.
• To avoid short circuit or electric shock, do not touch the metal parts of the
connecting cable clips.
• To avoid electrical shocks, be careful to avoid shorting live lines with the
connection cables.
DANGER
WARNING
• To avoid electric shock and short-circuit accidents, use only the specied test
leads to connect the instrument input terminals to the circuit to be tested.
• To avoid electric shock, do not exceed the lower of the ratings shown on the
instrument and connection cords.
To prevent an electric shock accident, conrm 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.
CAUTION
• The cable is hardened under the 0°C (32°F) or colder environment. Do not bend or
pull cables in such environments to avoid tearing insulation or breaking the cable.
• Connecting to the BNC jacks on modules
Do not use a metal BNC connector. If you connect a metal BNC cable to an insulated
BNC connector, the insulated BNC connector can be damaged and the instrument
may be damaged.
• To prevent cable damage, do not step on cables or pinch them between other objects.
Do not bend or pull on cables at their base.
IMPORTANT
• Use only the specied connection cables. Using a non-specied cable may satisfy the
specication requirements due to poor connection or other reasons.
• For detailed precautions and instructions regarding connections, refer to the instruction
manuals for your modules, connection cables, etc.

Measurement
What is the maximum display frequency?
Displaying waveforms by their sampled values with adequate resolution of
characteristics such as sine wave peaks requires a minimum of about 25
samples per waveform period.
Maximum display frequency is determined by the timebase.
What is aliasing (recording of non-existent waveforms)?
If the signal to be measured changes too fast relative to the sampling rate,
beginning at a certain frequency, non-existent slow signal uctuations are recorded. This phenomena is aliasing.
Actual Input Signal
Sampling Rate
Measured Waveform
Aliasing occurs when the sampling rate is longer
than half of the input signal period.
With the Memory function, the sampling rate can be signicantly affected by the timebase setting, so
care is necessary to avoid aliasing when selecting the timebase. Because the timebase determines the
maximum display frequency, the fastest possible timebase setting should be used.
When the signal can be recorded repeatedly, the auto-ranging function (p. 70) may be used to select
the optimum timebase.
Sampling Points
55
Page 61
Measurement Conguration
The sampling rate is automatically set to 1/100 of the selected timebase.
If MR8990 Digital Voltmeter Unit is installed, that channel's sampling rate is automatically set to 1/50 of
the selected timebase.
Example: When 8966 is installed as unit 1 (CH1 and CH2) and MR8990 as unit 2 (CH3 and CH4), and
the timebase is set to 1 s/div
Sampling rate of unit 1 (8966): 10 ms
Sampling rate of unit 2 (MR8990): 20 ms
To automatically set the timebase
When you press the
AUTO
key, a suitable timebase for the input signal is selected and
measurement starts. (This applies only to the Memory Function.)
Refer to “3.6 Measurement With Automatic Range Setting (Auto-ranging Function)” (p. 70).
• The timebase and sampling rate can be set independently. The sampling rate is selected depending on
the timebase setting.
• When the following timebase values are selected, displayed waveforms are compressed in the
horizontal (time axis) direction as shown.
20 ms/div → ×1/2,
10 ms/div → ×1/5
To minimize noise during measurement
If the sampling rate is too fast and the input waveform amplitude is small, the difference between
maximum and minimum values may become quite large as a result of sudden uctuations, such
as those caused by noise. To prevent this, select a slower sampling rate or enable the module's
lowpass lter (p. 63).
Common
The data refresh rate is not allowed to exceed the maximum sampling rate of the module.
During the period when data is not updated, the same data is measured, resulting in a stair-shaped
waveform.
Even when the same signal is sampled simultaneously by two modules, the data may differ due to
differences in sampling rate, frequency bandwidth, and frequency response.

• For range settings of 10 ms/div to 200 ms/div, when the printer setting (real-time print) is On, the realtime print is not performed. Perform printing manually after measurement is completed. (p. 112)
• When Auto-saving is On, the saving is not performed during the measurement. When measurement is
stopped, the data currently stored in the internal memory is saved.
When recording length is changed during measurement
Measurement data already stored in memory is discarded and measurement starts with the
newly set recording length.

• When measurement is started with the auto-ranging setting, the trigger output signal is output to the
external control terminal block's TRIG OUT terminal. Keep this in mind when performing auto-range
measurement while using the trigger output terminal.
• The auto-ranging function automatically selects settings for the input signal that is present when the
function is enabled. Start auto-ranging measurement after supplying the input signal (waveform).
• If the input signal of the lowest numbered channel selected for waveform display is extremely small,
the timebase will be set according to the input signal of the next lowest channel.
• If range could not be set for any channel where waveform display is On, a warning message will
appear and measurement will be interrupted.
• The auto-save and auto-print functions cannot be used when measuring with the auto-ranging
function.
• For low-frequency signals of less than 10 Hz, the optimal range cannot be selected automatically. Set
the range manually.
• Using the following modules disables the auto-range function:

• The X-Y waveform generated from the input signal is displayed in real time.
• By saving the displayed data in memory, data can be stored as well as printed.
• Similar to an X-Y pen recorder, waveform drawing can be controlled by simulated pen up/down
operation.
• Simultaneous observation of up to 8 X-Y phenomena is possible.
• Because waveform information is stored in memory, settings can be changed after measurement for
repeated synthesis.

About divided saving
• Large quantities of waveform data can be divided and saved as multiple les.
• Saving divided data automatically makes a folder then creates one or more waveform les and an
index (IDX) le in that folder. The IDX le can be used to load the data in the waveform le(s) as a
batch.
• When divided saving is selected, delete save (p. 76) is not available.
• Automatic divided saving is not possible when using the memory division function.
Refer to “Divided les are loaded together.” (p. 95) or “12 Memory Division Function” (p. 237).
Thinning
A large amount of space is required to save les in the text format. Data thinning reduced the le size.
Example: When [1/2] is set, every second data item is saved.
The number of data items is reduced to 1/2 the original amount.
