■ Probe Connection, Measurement Voltage Input Maximum input voltage ratings for the input units and the input
terminals of the 8826 are shown below. To avoid the risk of electric shock and damage to the units, take care not to exceed these ratings.
The maximum rated voltage to earth of the input units (voltage between input terminals and 8826 frame ground, and between inputs of other analog units) is shown below. To avoid the risk of electric shock and damage to the units, take care that voltage between channels and between a channel and ground does not exceed these ratings.

DANGE
The external I/O terminal and the unit have a common GND. The maximum rated voltage to earth rating applies also if an input
attenuator or similar is used. Ensure that voltage does not exceed these ratings.
When measuring power line voltages with the 8936 or 8938, always connect the probe to the secondary side of the circuit breaker. Connection to the primary side involves the risk of electric shock and damage to the units.
Before using the instrument, make sure that the insulation on the connection cords is undamaged and that no bare conductors are improperly exposed. Using the instrument under such conditions could result in electrocution. Replace the connection cords specified by Hioki.
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.
■Logic Probe Connection The logic input and 8826 Unit share a common ground. Therefore, if powe
is supplied to the measurement object of the logic probe and to the 8826 from different sources, an electric shock or damage to the equipment may result. Even if power is supplied from the same system, if the wiring is such that a potential difference is present between the grounds, current will flow through the logic probe so that the measurement object and 8826 could be damaged. We therefore recommend the following connection method to avoid this kind of result. Refer to Section 2.5 for details. (1) Before connecting the logic probe to the measurement object, be sure
that power is supplied from the same outlet box to the measuremen object and the 8826 using the supplied grounded 2-wire power cord.
(2) Before connecting the logic probe to the measurement object, connec
the ground of the measurement object to the 8826 ground terminal. Also in this case, power should be supplied from the same source. Refer to Section 2.2 for grounding terminal details.

･ To avoid the danger of electric shock, never operate the instrument with
an input module removed. To use the instrument after removing an input module, install a blank panel over the opening of the removed module.
■ Preliminary Checks ･ Before using the instrument the first time, verify that it operates
normally to ensure that the no damage occurred during storage or shipping. If you find any damage, contact your dealer or Hioki representative.
･ Before using the instrument, make sure that the insulation on the
connection cords is undamaged and that no bare conductors are improperly exposed. Using the instrument under such conditions could result in electrocution. Replace the connection cords specified by Hioki
■ Power supply connections ･ Before turning the instrument on, make sure the source voltage
matches that indicated on the instrument’s power connector. Connection to an improper supply voltage may damage the instrument and present an electrical hazard.
■ Grounding the unit ･ To avoid electric shock and ensure safe operation, connect the power
cable to a grounded (3-contact) outlet. (refer to Section 2.2).
■ Usage Precautions for the Internal MO Drive (option) ･ Please do not attempt to disassemble the MO drive. ･ Laser radiation can be emitted when the MO drive is open. Avoid
looking directly into the laser when the MO drive is open. Maximum laser output is 50 mW (at 685 nm, pulsed).

Power supply matches Rated supply voltage (100 to 240 V AC: Voltage
fluctuations of 10% from the rated supply voltage are taken into
account.) and rated supply frequency (50/60 Hz). The AC power switch of the 8826 are set to OFF. Use only the supplied AC power cord.
The 8826 has no protective ground terminal, but is intended to be connected to a ground wire via the grounded three-core power cord supplied. In order to avoid electric shock accidents, be sure to connect the grounded three-core power cord supplied to a power supply socket one of whose terminals is properly grounded.
The microgap power switch construction necessitates that the product be used near a power outlet. When not in use and while making connections to the circuit to be tested, disconnect the product from the power source by unplugging it from the outlet.
(1) Verify that the AC power switch of the 8826 is set to OFF. (2) Plug the grounded three-core power cord supplied into the AC power
connector on the right side of the 8826.

CAUTIO
・Never connect the probe to the 8826 while the probe is already
connected to the measurement object. Otherwise there is a risk of electric shock.
・Be sure to use the input cord specified by HIOKI for 8826.
An insulated BNC is used to prevent electric shock. Note that using a metal BNC may run the risk of electric shock, since the input L-terminal and metal part of the BNC connector have the same potential.
・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.

WARNIN
・Never connect the connection cable to the unit while it is connected to the
measurement object, to avoid electric shock.
・The BNC connectors for each channel and the miniature connection terminals share a
common ground. Do not connect both types of terminals at the same time.
・When the PREAMP measurement mode is selected, voltage (15 V at 2 mA) is applied
internally to the BNC connector when measurement starts. To avoid electric shock and damage to measurement objects, select a measurement mode other than PREAMP or turn the unit off when connecting a sensor or probe to the BNC terminals.
・Before using an Internal Preamp Type Acceleration Sensor, be sure that it conforms to
the 8947 specifications (15 V at 2 mA). Using a non-conforming sensor could result in damage to the sensor.
Acceleration sensors compatible with the 8947 CHARGE UNIT are as follows: ・Acceleration sensors with internal preamp (BNC connector with 15 V at 2
mA operating power)
・Charge-output type accelerator sensors (miniature 10-32 connection
terminal)
■Connecting an Internal Preamp Type Acceleration Sensor (PREAMP and VOLTAGE modes)
Use a cable with BNC connector to connect the pickup sensor to the unit in PREAMP mode. We recommend the Model L9198 CONNECTION CORD for the VOLTAGE mode. (1) Push the BNC plug onto the connector on the
unit, and turn it clockwise until it locks.
(2) To remove the BNC plug, push the plug ring

.5 Logic Probe Connection
DANGE
The logic input and 8826 Unit share a common ground. Therefore, if powe is supplied to the measurement object of the logic probe and to the 882 from different sources, an electric shock or damage to the equipment ma result. Even if power is supplied from the same system, if the wiring is suc that a potential difference is present between the grounds, current will flow through the logic probe so that the measurement object and 8826 could b damaged. We therefore recommend the following connection method t avoid this kind of result. (1) Before connecting the logic probe to the measurement object, be sur
that power is supplied from the same outlet box to the measuremen object and the 8826 using the supplied grounded 2-wire power cord.
(2) Before connecting the logic probe to the measurement object, connec
the ground of the measurement object to the 8826 ground terminal. Als in this case, power should be supplied from the same source. Refer t Section 2.2 for grounding terminal details.
unction Groun errminal
In this case too, obtain power from th same supply.
・The logic input is located on the top side of th
unit. Up to eight probes can be connected.
・Since one logic probe can record 4 channels, th
combined maximum recording capability for logi waveforms is 32 channels.
・Connect the probe by aligning the groove on th
plug with the ridge on the connector.

NOTE
Clamp-on probe should only be connected to the secondary side of a breaker, so the breaker can prevent an accident if a short circuit occurs 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.
Before using the 9018-10, 9132-10 CLAMP ON PROBE, be sure to carefully read its instruction manual and familiarize yourself with the operation principles of this product.
The HIOKI 9018-10, 9132-10 CLAMP ON PROBE can be used to perform current measurement. This probe has a voltage output. The 8826 is designed for voltage input. It cannot be used to perform current measurements by itself.
Connections
Connect the BNC connector of the 9018-10, 9132-10 CLAMP ON PROBE to the analog input of the 8826, as shown in the illustration.
･ The 8826 will indicate measurement results as voltage. ･ Using the scaling function, units can be converted to "A" for display.
See Section 9.7.2.
･ When the clamp-on probe is used for measurement, the measurement
precision will be affected both by the 8826 precision and clamp-on probe precision ratings. The same is true for cases where other clamps are used.
･ When using the 9018, 9132 CLAMP ON PROBE, always use the 9199
CONVERSION ADAPTOR.

.9 Care of Recording Paper
Care of recording paper
・While unopened, thermal paper will not be affected by the environment,
provided that ambient temperature and humidity do not exceed normal levels. For long-term storage, temperature should be lower than 40. Low temperatures cause no problem.
・After opening, protect the paper from strong light, to prevent discoloration.
Storing data
The recording paper uses a thermochemical reaction. Note the following points:
・To avoid discoloration, do not leave recording paper in direct sunlight. ・Store at not more than 40℃ and 90%RH. ・To keep definitive data, make photocopies of the recordings. ・Thermal paper will blacken when brought into contact with alcohol, ester,
ketone, or other volatile organic substances.
・If the thermal paper absorbs an organic solvent such as alcohols or ketones
it may no longer develop properly, and recorded information may fade. Soft PVC film and transparent contact adhesive tape contain such solvents, so avoid using them with recordings.
・Avoid interleaving the thermal recordings with damp diazo copies.

Maximum input voltage ratings for the input units and the input terminals of the 8826 are shown below. To avoid the risk of electric shock and damage to the units, take care not to exceed these ratings.
The maximum rated voltage to earth of the input units (voltage between input terminals and 8826 frame ground, and between inputs of other analog units) is shown below. To avoid the risk of electric shock and damage to the units, take care that voltage between channels and between a channel and ground does not exceed these ratings.
The maximum rated voltage to earth rating applies also if an input attenuator or similar is used. Ensure that voltage does not exceed these ratings.
When measuring power line voltages with the 8936 or 8938, always connect the probe to the secondary side of the circuit breaker. Connection to the primary side involves the risk of electric shock and damage to the units.

NOTE
To avoid electric shock accident, before removing or replacing an input module, confirm that the instrument is turned off and that the power cord, connection cords, and thermocouples are disconnected.
To avoid the danger of electric shock, never operate the product with an input module removed. To use the product after removing an input module, install a blank panel over the opening of the removed module.
Before using the product, make sure that the insulation on the connection cords is undamaged and that no bare conductors are improperly exposed. Using the product under such conditions could result in electrocution. Replace the connection cords specified by Hioki.
・When making measurements on an AC power line for example, using a voltage
transformer, be sure to connect the voltage transformer ground terminal to ground.
･ If the 8937 VOLTAGE/TEMP UNIT’s input terminal is exposed to a strong
draft, loss of thermal equilibrium at the input may result in measurement error. When taking measurements under such conditions, arrange the unit in such a manner that the input terminal is protected for direct exposure to drafts.
･ If ambient temperature changes suddenly, loss of thermal equilibrium can
result in measurement error. When this occurs, allow the unit to acclimate to the new temperature for about one hour, then take measurements after thermal equilibrium is reached.

Status conditions:
Time axis range (time/div): value set automatically, Memory segmentation: OFF
NOTE
・Because the auto-range function performs automatic setting for the input
signal present at the time the function is executed, input a signal before executing the function.
・If for the input signal for this channel there is only a small difference
between the maximum value and the minimum value in the range of highest sensitivity (5 mV/DIV), the setting is made by taking the next higher channel.
・If the range cannot be determined, for all channels for which the waveform
display is on. A warning message appears, and measurement is abandoned.
・When the auto range function is activated by pressing the AUTO key, a
trigger output signal is generated. This should be taken into consideration when using both the trigger output and the auto range function.
・The auto-range function does not operate on channels for which the
CHARGE or PREAMP measurement mode is selected on the 8947 CHARGE UNIT.
