Conventions used in this manual
The following symbols in this manual indicate the relative importance of
cautions and warnings.
Measurement categories (Overvoltage categories)
This instrument complies with CAT safety requirements.
To ensure safe operation of measurement instruments, IEC 61010 establishes
safety standards for various electrical environments, categorized as CAT
to
CAT
, and called measurement categories. These are defined as follows.
CAT
: Secondary electrical circuits connected to an AC electrical outlet through
a transformer or similar device.
CAT
: Primary electrical circuits in equipment connected to an AC electrical
outlet by a power cord (portable tools, household appliances, etc.)
CAT
: Primary electrical circuits of heavy equipment (fixed installations)
connected directly to the distribution panel, and feeders from the
distribution panel to outlets.
CAT
: The circuit from the service drop to the service entrance, and to the
power meter and primary overcurrent protection device (distribution
panel).
Higher-numbered categories
correspond to electrical
environments with greater
momentary energy. So a
measurement device designed
for CAT
environments can
endure greater momentary
energy than a device designed
for CAT
.
Using a measurement instrument in an environment designated with a highernumbered category than that for which the instrument is rated could result in a
severe accident, and must be carefully avoided.
Never use a CAT
measuring instrument in CAT , ,or environments.
The measurement categories comply with the Overvoltage Categories of the
IEC60664 Standards.

■ 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
R
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.
■Logic Probe Connection
The logic input and 8826 Unit share a common ground. Therefore, if powe
r
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
t
object and the 8826 using the supplied grounded 2-wire power cord.
(2) Before connecting the logic probe to the measurement object, connec
t
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.

■ Replacing the input units
･ 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 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).
A
laser warning label is attached to the bottom of the 8826 Uni

■ Installation environment
･ This instrument should be installed and operated indoors only, between 5 and
40℃ and 35 to 80% RH.
･ Do not store or use the instrument where it could be exposed to direct
sunlight, high temperature or humidity, or condensation. Under such
conditions, the instrument may be damaged and insulation may deteriorate
so that it no longer meets specifications.
･ To avoid electric shock, do not allow the instrument to get wet, and do not
use it when your hands are wet.
･ Do not use the instrument where it may be exposed to corrosive or
combustible gases. The instrument may be damaged or cause an explosion.
■ Before powering on
･ The microgap power switch construction necessitates that the instrument be
used near a power outlet. When not in use and while making connections to
the circuit to be tested, disconnect the instrument from the power source by
unplugging it from the outlet.
■
Using a connection cable
･ Use only the specified connection cord. Using a non-specified cable may
result in incorrect measurements due to poor connection or other reasons.
■
Storing
･ When the unit is not to be used for an extended period, set the head
up/down lever to the "head up" position. This will protect the printer head
and prevent deformation of the rubber roller.
■ Precautions on carrying this equipment
･ The terminal guard of the equipment protects the inputs. Do not hold this
guard when carrying the equipment. To carry this equipment, use the
handle. See section 1.2.
■
Shipping
･ Remove the printer paper from the unit. If the paper is left in the unit, paper
support parts may be damaged due to vibrations.
･ To avoid damage to the instrument, be sure to remove the floppy disk, MO
disk, PC card, and SCSI cable before shipping.

NOTE
■ Using a printer
･ Avoid using the printer in hot, humid environments, as this can greatly reduce
printer life.
■
Recording paper
･ This unit uses a thermal printer. The recording paper supplied has
characteristics finely tuned for use with the printer.
Using recording paper of a different specification may not only result in
impaired printing quality, but even prevent the printer from operating. Always
use the HIOKI specified instrument.
･ Printing is not possible if the recording paper is loaded wrong-side up. (See
Section 2.8)
