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.
• Never use a measuring instrument that lacks category labeling in a CAT II to
CAT IV measurement environment. Doing so could result in a serious accident.
CAT II: When directly measuring the electrical outlet receptacles of the primary electrical
circuits in equipment connected to an AC electrical outlet with 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)

Operation Precautions
Handling the Instrument and Modules
• Do not use the modules or the cables with circuits that exceed those ratings or
specications.
Doing so may damage the instrument or cause it to become hot, resulting in
bodily injury.
Even including any devices, such as an attenuator, in the input terminal will
never increase the maximum rated voltage to earth. Take care of the connection
not to allow any input voltage to exceed the maximum rated voltage to earth.
• To avoid an electric shock, do not remove the instrument’s cover and the
modules’ cases.
The internal components of the instrument carry high voltages and may
become very hot during operation.
• To avoid an electric shock, before removing or replacing an input module,
conrm that the instrument is turned off and that the connection cords are
disconnected.
• To avoid the danger of an electric shock, never operate the instrument with an
input module removed. To use the instrument with a module removed, install a
blank panel over the opening of the removed module.
• To prevent the instrument damage or an electric shock, use only the screws
that are originally installed for securing the module in place.
If you have lost any screws or nd that any screws are damaged, please contact
your Hioki distributor for a replacement.
DANGER
WARNING
CAUTION
• To avoid damage to the instrument, protect it from physical shock when
transporting and handling it. Be especially careful to avoid physical shock due
to dropping it.
• The mounting screws must be rmly tightened or the module may not perform

• With some external storage device, the instrument may not start up if it is turned on while the
external storage device is inserted. In such a case, turn on the instrument rst, and then insert
the external media. Prior testing is recommended.
• The instrument does not support particular kind of USB ash drives, such as those that require
ngerprint authentication or a password.
• When saving or loading data, insert the storage device before selecting data to be saved.
When the storage device is not inserted, no devices are not displayed in the le list.
• All storage devices (built-in drive [SSD], USB ash drive, and CF card) have a limited service
life. After extensive use for a long period, saving and loading data may be disabled. In that
case, replace the device with a new one.
• The built-in drive (SSD) is a consumable part. When the saved data reaches the capacity (about
60 TB), no further data can be recorded. In such a case, the SSD should be replaced with a
new one.
• When the instrument is left powered off for a one year or more, the data saved on the built-in
drive (SSD) may be lost. Be sure to back up the data if the instrument is left powered off for a
long time.
• Devices the automatic data saving supports are the built-in drive (SSD), a USB ash drive, and
a CF card.
• Data can also be automatically saved on a USB ash drive; however, we recommend using
Hioki optional CF card instead for data protection.

Operation Precautions
DANGER
When measuring power line voltage
• Connect the connecting cables to only the secondary side of a breaker. Even
if a short-circuit occurs on the secondary side of the breaker, the breaker will
interrupt a short-circuit current. Do not connect them to the primary side of the
breaker because an unrestricted current ow could damage the instrument and
facilities if a short circuit occurs.
• To prevent an electrical shock and a bodily injury, do not touch any input
terminals on the VT (PT), CT or the instrument when they are in operation.
• Do not leave the measurement cables connected to the instrument in an
environment where voltage surges exceeding the maximum input voltage may
occur. Subjecting the instrument to such a voltage may result in damage to the
instrument or a serious accident.
• 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 a short-circuit or an electric shock, do not touch the metal parts of the
connecting cable clips.
• To avoid electrical shock, be careful to avoid shorting live lines with the
connection cable chips.
WARNING
To avoid an electric shock and a short-circuit accident, use only the specied test

2.7 Adjusting the Zero Position (zero-adjustment)
This operation compensates potential deection of modules and sets the reference potential of the
instrument to 0 V.
The compensation operation is performed for all channels and ranges.
Before performing zero-adjustment
• Warm up the instrument for about 30 minutes after the power-on to stabilize the internal temperature of
the modules, and then perform zero-adjustment.
• Note that zero-adjustment cannot be performed during measurement.
• Key operation is not accepted during zero-adjustment.
• The time required for zero-adjustment varies depending on types and the number of modules installed
in the instrument. (The operation may take several seconds.)
Procedure

Zero-adjustment has no effect on the 8969 and U8969 Strain Unit.
(Adjust the zero position using the auto-balance. (p. 183))
Perform zero-adjustment in the following cases.
• When a module has been replaced
• When the instrument has been cycled.
• When settings has been initialized (system reset)
• When measurement mode has been switched between DC and RMS on Model 8971 Current Unit, 8972
DC/RMS Unit, or U8974 High Voltage Unit
• When the ambient temperature has changed signicantly
The zero-position drift* may occur.
* Drift:
This means a spurious output caused by a shift in an operating point of an operational amplier. Drift can
occur due to changes in temperature and due to component aging over a period of use.

Measurement
57
Setting Measurement Conditions
What is the maximum display frequency?
To plot sine waves that allow you to observe those peaks on the LCD, the
instrument needs to sample the waveforms at least 25 points per cycle.
The maximum display frequency varies depending on the timebase
setting.
If instrument plots non-existent waveforms (aliasing)
If a measured signal uctuates at a higher frequency compared to the
specied sampling speed, the instrument can probably plot non-existent
waveforms uctuating at a lower frequency than that of realistic signal
when the signal frequency reaches a certain level. This effect is called aliasing.
Actual input signal
Sampling points
Sampling rate
Observer waveform
Aliasing occurs because the sampling rate is slower than
the cycle of the input signal.
For the memory function, because the sampling rate can signicantly vary according to the timebase
setting, select the timebase setting carefully to avoid aliasing from occurring. Since the timebase setting
determines the maximum display frequency, perform measurement at as fast timebase setting as
possible.
When recording signals repeatedly, the auto-range function (P. 76) is useful.
The sampling rate is automatically set to 1/100 of the selected timebase.
When Model MR8990 Digital Voltmeter Unit is installed, the sampling rate of its channels is automatically
set to 1/50 of the selected timebase.
Example: When Model 8966 is installed as Unit 1 (CH1 and CH2) and Model MR8990 as Unit 2 (CH3
and CH4), then the timebase is set to 1 s/div
Sampling rate of Unit 1 (Model 8966): 10 ms
Sampling rate of Unit 2 (Model MR8990): 20 ms
To automatically set the timebase
Pressing the AUTO key selects a suitable timebase for an input signal and starts measurement.
(This function can be used in the memory function only.)
Refer to “3.6 Measurement With Automatic Range Setting (Auto-Ranging Function)” (p. 76).
58
Setting Measurement Conditions
• The timebase and sampling rate can be set independently. The sampling rate is selected depending on
the timebase setting.
• As mentioned below, when the former timebase settings are selected, the instrument displays
waveforms that are demagnied horizontally (in the time axis direction) at the latter scale size.
20 ms/div, ×1/2; 10 ms/div, ×1/5
To perform measurement minimizing the effect of noise
While measuring a waveform that usually uctuates only slightly, with a fast sampling rate set, a
difference between the maximum and minimum values may become large if the amplitude of the
waveform changes sharply. To prevent this effect, select a slower sampling rate or enable the
module’s low-pass lter (P. 67).
3
Note common to
The data refresh rate is not allowed to exceed the maximum sampling rate of the module.
During the period while data is being not updated, the same data is measured, with the result that stair-
like waveforms are plotted.
Even when a single signal is sampled simultaneously by two modules, the data may differ with one
another due to differences in the sampling rate, frequency bandwidth, and frequency response.

However, when the Model MR8990 Digital Voltmeter Unit is installed, the number of samples is as follows:
• When only Model MR8990 is installed
Number of samples in a division: 50 samples
Total number of samples in the recording length:
Set recording length (divisions) × 50 samples + 1
• When both Model MR8990 and other modules are installed

Each recording length division includes 100 samples, each of which consists of two values: the maximum
and minimum values.
Data obtained with Model MR8990 using the recorder function has a resolution of 16 bits.
When recording length is set to [Cont.]
• The instrument saves data that is obtained during the period that lasts until the measurement terminates
and has the maximum recording lengths (20,000 div for Model MR8847-51, 80,000 div for Model
MR8847-52, and 160,000 div for Model MR8847-53).
• For the range settings of from 10 ms/div to 200 ms/div, the instrument does not perform the real-
time print even when the printer setting (real-time print) is set to on. Perform printing manually after
measurement terminates (P. 124)
• When the auto-saving is set to on, the instrument does not save any data during the measurement.
When the measurement terminates, the data presently written in the internal memory is saved.
When the recording length is changed during measurement
Measured data already acquired in the memory is discarded, and measurement is started using the
newly set recording length.

Conguring Input Channels Settings
• Setting the input coupling set to GND disables the range settings because the waveforms seem to
have no amplitude.
• Filter attenuation may inuence correct range settings.
• When choosing trigger settings, set the vertical axis (voltage axis) range rst. When you change the
range after specifying the trigger, the trigger setting is changed.
• When using the variable function, set the vertical axis (voltage axis) range rst. When you change the
range setting after applying the variable function, observation of waveforms with sufcient precision
may not be possible.
• When using the variable and scaling functions together, enable the scaling function rst. When
you enable the scaling function after enabling the variable function, an unintended display may be
displayed.
This section describes the setting procedure for logic channels (standard logic terminals: LA through LD,
expansion logic terminals: L1A through L8D).

This function is enabled only for measurement with the analog modules with the memory function
enabled.
When you press the AUTO key after inputting signals to an analog module and select [Auto Range],
the horizontal axis range (timebase), vertical axis (voltage axis) range, and zero position are selected
automatically, and then measurement is started.
The timebase is set to the lowest numbered channel of the channels with those waveform display setting
set to on. In addition, it is set automatically so that waveforms with a length of from one cycle to 2.5 cycles
in 25 divisions are recorded.

Measurement in Automatic Range Setting (Auto-Range Function)
• When measurement is started in the auto-range setting, the trigger output signal is output from 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-range function automatically selects settings for an input signal when the function is
enabled. After supplying an input signal (waveform), start auto-range measurement.
• If the input signal of the lowest numbered channel with the waveform display setting set to on
have extremely low amplitude, the timebase is set according to the input signal of the next lowest
numbered channel.
• If the range cannot be set for any channels with waveform display setting set to on, a warning
message is displayed, with the result that the measurement in progress is interrupted.
• The auto-range measurement disables the auto-saving and auto-printing functions.
• For a low-frequency signal of less than 10 Hz, the optimal ranges cannot be selected automatically.
Set the ranges manually.

X-Y Recorder
To redraw the X-Y composite curves in different X-Y composite curve display
settings
• Even after the X-Y composite curve display is cleared, the waveform data is still retained in
the memory. This makes it possible to redraw the X-Y composite curves in different settings,
which include the display format, display color, channels used for plotting the curves,
channel magnication ratio, and channel offset, from those previously set. (Select [Redraw])
Executing [Redraw] update the screen and printout data.
(Until [Redraw] is not executed, the screen and print data are not updated, even if the
settings are changed.)
• The X-Y composite curves can also be redrawn by operating the jog dial and shuttle ring.
Jog dial Plots the X-Y composite curves and plays back the plotting of the curves inversely
in one sample increments.
Shuttle ring Plots the X-Y composite curves and plays back the plotting of the curves
inversely at speed proportional to the rotation angle.
• To play back the plotting of the X-Y composite curves inversely, plot curves in the direction of earlier
data. Erasing the X-Y composite curves is not possible.
• If the measured data exceeds 4,000,000 samples, it is only possible to redraw up to 4,000,000
samples in the past, counting backward from the point when measurement terminated. The
instrument discards waveform data obtained earlier.
• Redrawing the X-Y composite curves with the jog dial and shuttle ring affects the X-Y composite
curves displayed on the screen only and does not affect the printout data. To print the same X-Y
composite curves as shown on the screen, use the screenshot function (p. 130).

Observing X-Y Composite Curves
4.4 Observing X-Y Composite Curves
Up to 4,000,000 samples of waveform data are written in the memory, and you can observe those
measured values using Cursors A and B. (p. 134)
The bar at the top of the screen indicates the amount of the occupied memory.
When the number of samples reaches 4 million, the sign [OVER] appears
next to the screen bar at the top.
