Overvoltage Categories (CAT)
This instrument complies with CAT II safety requirements. This instrument’s
input modules com ply wi th CAT I or CA T II sa fety r equirem ents. T o en sure sa fe
operation of measuremen t instr uments, IE C 60664 es tablish es saf ety standa rds
for various electrical env ironments, catego rized as CAT I to CAT IV, and ca lled
overvoltage categories. These are defined as follows.
CAT I Secondary electrical
circuits conn ected to
an AC electric al outlet through a transformer or similar
device.
CAT II Primary electri cal cir -
cuits in equipment
connected to a n 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) con-
nected directly to the distribution panel, and feeders from the distribution
panel to outlets.
CAT IV The circuit from the service drop to the service entrance, and to the
power meter and primary overcurrent protection device (distribution
panel).
Higher-numbered cate gories correspond to electrical enviro nments with greater
momentary energy. So a measurement device designed for CAT III environments can endure greater momentary energy than a device designed for CAT II.
Using a measurement instrument in an environment designated wit h a highernumbered category th an that for which the in strument is rated c ould result in a
severe accident, and must be carefully avoided.

Operating Precautions
Handling the Probes
Handling the CD
• Avoid stepping on or pinching cords, which could damage the probe insulation.
• To avoid breaking the cords, do not bend or pull them.
Use only the specifi ed connection cords. Using a non-sp ec ifi ed c ab le m ay re su lt
in incorrect measurements due to poor connection 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, becau se there is a d anger of sc ratch ing 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
temperature or humidity, as there is a danger of warping, with consequent loss
of data.
• To remove dir t, dust, or fin gerprin ts from the disc , wipe with a dry cloth, or use
a CD cleaner. Always wipe radially from the inside to th e 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 syste m that arises
from the use of this CD , or for any probl em related to the purchase of a Hi oki

2.2 Connecting Cords
2.2 Connecting Cords
When measuring analog signals
Connect the cables or sensors to the input module.
When measuring logic signals
Connect the logic probe(s) to the LOGIC terminal(s) on th e instrument.
When measuring power line voltage
• The connection cords should only be connected to the secondary side of a
breaker, so the breaker can p revent an ac cident if a short c ircuit oc curs. Connections should never be made to the primary side of a breaker, because unrestricted current flow could cause a serious accident if a short circuit occurs.
• When connectin g cl ip- ty pe te st le ads to live terminals, be ve ry ca reful to avoid
accidentally shorting conductors together and causing a serious accident.
• To prevent elec trical sh ock and pers onnel injur y, do not touch any input terminals on the VT (PT), CT or the instrument when they are in operation.
• Do not permanently connect the device in an environment where voltage
surges exceeding th e maximum input voltage may occur. Failure to observe
this precaution could result in damage to the device and personal injury.
Connecting to the BNC jacks on input modules
When disconnecting the BNC connec tor, be sure to release the lock be fore pulling off the connector. Forcibly pulling the connector without releasing the lock, or
pulling on the cable, can damage the connector.
For voltage
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.
Use only the specif ied c onn ec tio n c or ds . Usi ng a non -s pe ci fie d c able may result
in incorrect measurements due to poor connection or other reasons.
For temperature measurement
When connecting a thermocouple using a wire run of mor e than 3 meters, the
EMC environment in cluding possible influen ce of external noise mu st be taken
into consideration.
For detailed precautions and instructions regarding connections, refer to the documentation of input modules, co nnec ti on cords, etc.

2.2 Connecting Cords
Before connecting a logic probe to the measurement object
To a void electric shock and short circuit accidents or damage to the instrument, pay attention to the following:
• The ground pin in the LOGIC connector (plug) of the Model 9320-01 and
9327 Logic Probes (and legacy Models 9306 and 9320) is not isolated
from this instrument’s ground (common ground).
Use grounding-type polarized power cords for the measurement object
and this instrument, and obtain power from the same main s ci rcuit.
Connecting to different mains circuits or using a non-grounding power
cord may cause damage to the measurement object or this instrument
because of current flow through the logic probes resulting from potent ial
difference between the grounds of the different wiring syst ems.
To avoid these problems , we recommend the following c onnection procedure:
• Maximum logic probe input voltages are as follows. Do not measure if
the maximum voltage would be excee ded, as damage the instrumen t or
personal injury may result.
Model 9327 Logic Probe: +50 VDC
Model 9320-01 Logic Probe: +50 VDC
Model MR9321-01 Logic Probe: 250 Vrms (HIG H range), 150 Vrms (LOW
range)
Do not allow the metal tip of a logic probe to caus e a short between conductors on the measurement object. Nev er touch the metal tip of a probe.

2.3.1 Storage Media (Inserting a CF Card and USB Memory Stick)
• If damage occurs to the hard disk or interna l memory, we cannot restore or
analyze the lost data. No compensation will be provided, regardless of the type
or cause of the prob lem or damage.We therefore recomme nd maintaining a
backup of any important data.
• Be careful to avoid inserting a media backwards or upside-down. The media or
the instrument could be damaged.
• Never insert or eject a media while it is being accessed by the instrument
(while LED next to SAVE key is lit). Data on the media could be lost.
• Do not transport the instrument while a USB memory stick is connected. Damage could result.
• Do not subject the hard disk to extreme shock or vibration. Doing so may damage the hard disk.
• Use the hard disk in an en vironment with a temperature of 5 °C to 40°C, and
humidity of 20%RH to 80%RH (non-condensation).
• Do not operate the instrument at a slanted angle. It may not work properly.
• Some USB memory st icks are susceptible to static electric ity. Exercise car e
when using such products because static electricity could damage the USB
memory stick or cause malfunction of the instrument.
• With some USB memory sticks, the instrument may not start up if power is
turned on while the USB memory stick is inserted. In such a case, turn power on
first, and the n i n se rt t he US B m em ory s ti ck. It is recommended t o t r y ou t o pe r ation with a USB memory stick before starting to use it for actual measurements.
• When saving or l oading data, insert th e storage medi a before specifying it. If
the media is not inserted, the file list display will not appear.
• Media have a limi ted service life. After extensi ve use over a long period, da ta
retention and readou t ma y bec om e no n- fun ctiona l. In s uc h a c ase , you sh oul d
procure new media.
• Automatic saving of data is possible only on hard disk or CF Card media.

2.4 Loading Recording Paper
Handling and Storing Recording Paper
The recording paper is thermally and chemi cally sens itized. Ob serve the following precautions to avoid paper discoloration and fading.
Avoid exposure to direct sunlight.
Do not store thermal
paper above 40°C or
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.
The print head and surrounding metal parts can become hot. Be careful to
avoid touching these parts.
Be careful not to cut yourself with the paper cutter.
• Please use only th e s pec if ied r ecor din g pa per. Using non-speci fie d paper ma y
not only result in faulty printing, but printing may become impossible.
• If the recording paper is skewed on the roller, paper jams may result.
• Printing is not possible if the front and back of the recording paper are
reversed.
• 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.

With the Recorder function, each data sample consists of the maximum and minimum values acq uired in the specified sampl ing period. So each data sa mple

When input wave form variation is slig ht, the difference b etween maximum and
minimum values (breadth, or width) can be inordinately large if the sampling

3.4 Setting Measurement Configuration
Description
Selecting the
time axis range
Refer to the table below when setting the time axis range.
For example, to measure a 100 kHz waveform, the ma ximum display f requency se tting range according to the table is 200 kHz - 800 kHz. If the maximum display frequency is set to 400 kHz, setting the time axis ran ge to 10 μs/di v is recom mended .
What is the maximum display frequency?
Displaying waveforms by their sampled values
with adequate resol ution of char acterist ics su ch
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 fluctuations are
recorded. This phenomena is aliasing.
With the Memory function, the sampling rate can be significantly affected by the
timebase setting, so care is necessary to avoid aliasing when selecting the
timebase. Because the timebase determ ines the maximum di splay frequency,
the fastest possible timebase setting should be used.
When the signal can be recorded repeatedly, the auto-ranging function (
p.58) may be used to select the optimum timebase.
The sampling rate is automatically set to 1/100 of the selected time axis range.

Chapter 3 Measurement Procedure
To minimize noise during measurement
If the sampling rate is set too fast, when the in put waveform amplitude is small, the difference betwe en m ax imu m an d mi nimum values
may become quite large as a result of sudden impulses such as
noise. To pr ev ent suc h phen ome na, select a slower sampli ng r ate or
enable the input module's lowpass filter ( p.52).
_______________________________________________________________
Common
The data refresh rate is not allowed to exceed the maximum sampling rate of the
input module.
During the period when data are not updated, the same data are measured,
resulting in a stair-shaped waveform. Even when the same signal is sampled
simultaneously by two un its, the data may differ due to differences in samp ling
rate, frequency bandwidth, and frequency response.

• Due to the influence of filt er atte nuatio n, cor rect range setti ng may sometime s
not be possible.
• When making trigger s ettings, set the v ertical axis ( voltage axis) range fir st. If
the range is changed after specifying the trigger, the trigger setting may
change.
• When using the Variable function, set the vertical axis (voltage axis) range first.
If the range is changed after specifying the Variable setting, observation with
sufficient precision may not be possible.
• When using the Variable and Scaling functions together, make the Scaling set-
tings first. If Scaling settings are made after selecting the Variable function, the
intended display result may not be achieved.

When measurement is stopped, waveform data f or up to 4,000, 000 samples before the current p oint
can be played back (redrawn) by the pen, similar to using a video recorder, starting from any specified point. This operation applies to all channels. The playback speed can be specified. (It can also
be changed during playback.) Waveform is only playbacked on the screen and will not affect the
printout data. To print the same waveforms as shown on the screen, use hard copy (
Measurement start/stop and pen up/down can be controlled via the external control terminal. ( p.28 9)
p.98).
Redrawing with different waveform display settings
• Also after clearing the waveform display, waveform data are stil l retained by
the unit. This make s it possi ble to cha nge settings for display fo rmat, displa y
color, synthesis channels, channel zoom and offset before redrawing the
waveform by selecting [Redraw].
When [Redraw] is executed, the screen and printout data will be renewed.
(As long as [Redraw] is not run, the screen and print data are not refreshed,
even if the setting is changed.)
• Using the Jog & Shuttle knobs for redrawing is also possible.
Jog Move back and forth in the redrawing process in increments of 1
sample.
Shuttle Move back and forth in the redrawing process at a speed corre-
sponding to the rotation angle.

• When moving backwa rds, the wavefor m will b e draw n in the directi on towa rds
earlier data. Erasing the waveform is not possible.
• If the measurement exceeds 4,000,000 samples, redrawing is possible only up
to 4,000,000 sam ples in the past, counting backwards from the point w here
measurement was stopped. Earlier waveform data are lost.
• Redrawing with the jog-shuttle is only reflected on the screen and will not affect
the printout data. To pri nt the same waveforms as shown on the screen, use
hard copy ( p.98).
4.4 Waveform Observation
Waveform data for up to 4,000,000 samples are stored in memory, and an A/B cursor pair can be

5.2 Saving Data
About divided saving
• Large quantities of waveform data can be divided and saved as multiple files.
• Saving divided data makes a folder automatically, and creates one or more
waveform files and an index (IDX) file in the folder.
• Then by loading t he IDX file, the data in the wa veform file(s) is loaded a s a
batch.
• When divided saving is selected, delete save is not available.
• When using the memory division function, divided saving cannot be performed
automatically.
See: "Batch load of waveform data" ( p.78)
"Chapter 12 Memory Division Function" (
Thinning
A large amount of s pace is requir ed for sav ing files i n text forma t. Data thin ning
enables a reduction in file size.
Example: When [1/2] is s et, every second data item is save d. The number of
data items is reduced to a 1/2.
