afety Notes
This manual contains information and warnings essential for safe operation of
the product and for maintaining it in safe operating condition. Before using
the product, be sure to carefully read the following safety notes.
Safety symbols
Accuracy
We define measurement tolerances in terms of f.s. (full scale), with the
following meanings:
f.s. (maximum display value or scale length)
The maximum displayable value or scale length. This is usually the name of
the currently selected range.

Indicates that incorrect operation presents significant danger of
accident resulting in death or serious injury to the user.
CAUTIO
N
Indicates that incorrect operation presents possibility of injury to the
user or damage to the equipment.
NOTE
Denotes items of advice related to performance of the equipment or
to its correct operation.
Conventions used in this manual
The following symbols are used in this Instruction Manual to indicate the
relative importance of cautions and warnings.
Measurement categories (Overvoltage categories)
This instrument complies with CAT II safety requirements.
To ensure safe operation of measurement instruments, IEC 61010 establishes
safety standards for various electrical environments, categorized as CAT I to
CAT IV, 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 III
environments can endure greater momentary energy than a device designed
for CAT II. Using a measurement 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 CAT I measuring instrument in CAT II, III, or IV environments.
The measurement categories comply with the Overvoltage Categories of the
IEC60664 Standards.

connected to a voltage source while its power supply is on.
WARNIN
G
To avoid electric shock and ensure safe operation, connect the power
cable to a grounded (3-contact) outlet.
N
otes on Use
Follow these precautions to ensure safe operation and to obtain the full
benefits of the various functions.
(1) Installation environment
(2) Power supply connections
・Check that the power supply is correct for the rating of the unit. (The AC
fuse is integrated in the unit.)
・The AC power power switch on 8835-01 is for AC power. If DC power is
being supplied and the switch on DC power adapter is set to ON, the 883501 will operate also if the power switch is set to OFF.

F/V UNIT, 8946 4ch ANALOG UNIT, 8947 CHARGE UNIT and input
terminals of the 8835-01 are shown below. To avoid the risk of electric
shock and damage to the unit, take care not to exceed these ratings.
The maximum rated voltage to earth of the 8936, 8937, 8938, 8939, 8940,
8946 and 8947 (voltage between input terminals and 8835-01 frame
ground, and between inputs of other input units) is shown below. To
avoid the risk of electric shock and damage to the unit, 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, 8936 or 8938 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.
Always use the optional connection cables. Any exposed metal sections
in a connection cable consist a risk of electric shock.

Logic probe input and 8835-01 share the same GND. Separate power
supply sources applied to the testing device and 8835-01 may result in
risk of electric shock and damage to the unit.
Even with the same power supply source, certain ways of wiring may
cause a variance in electric potential sending current that may damage
testing device and 8835-01. The following shows proper wiring to avoid
damage. For details, see Section 2.5.
(1) Before connecting logic probe to testing device, connect grounded
three-core power cord (attachment) to the device to be tested and
8835-01 and supply power from the same outlet.
(2) Before connecting logic probe to device to be tested, connect GND of
device to be tested with 8835-01 functional ground terminal. Make
sure that power is supplied from the same outlet.
When using grabber clips, the 9322’s maximum rated voltage to earth is
1500 V AC/DC; when using alligator clips, it is 1000 VAC/DC. To avoid
electrical shock and possible damage to the unit, never apply voltages
greater than these limits between the input channel terminals and
chassis, or across the inputs of two 9322s.
Maximum input voltage is 1000 VAC/2000 VDC. Do not measure voltage
in excess of these limitations, as doing so may damage the unit or
cause an accident that might result in injury or death.
