The maximum displayable value or the full length of the scale.
This is usually the maximum value of the currently selected range.
rdg. (reading or displayed value)
The value currently being measured and indicated on the measuring
instrument.
dgt. (resolution)
The smallest displayable unit on a digital measuring instrument, i.e.,
the input value that causes the digital display to show a "1".
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.
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.
Accuracy
We define measurement tolerances in terms of f.s. (full scale), rdg. (reading)
and dgt. (digit) values, with the following meanings:

Notes on Use
────────────────────────────────────────────────────
DANGER Probe Connection, Measurement Voltage Input
Maximum input voltage ratings for the input module and the input
terminals of the instrument are shown below. To avoid the risk of
electric shock and damage to the instrument, take care not to
exceed these ratings.
The maximum rated voltage to earth of the input module
(voltage between input terminals and main instrument frame
ground, and between inputs of other analog input modules) is
shown below. To avoid the risk of electric shock and damage
to the instrument, 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 8950, 8952 or
8953-10, always connect the probe to the secondary side of
the circuit breaker, so the breaker can prevent an accident if a
short circuit occurs. Connection to the primary side involves
the risk of electric shock and damage to the instrument.
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 products in
such conditions could cause an electric shock, so contact
your dealer or Hioki representative for replacements. (Model
9197, 9198.)

────────────────────────────────────────────────────
Notes on Use
────────────────────────────────────────────────────
DANGER External I/O terminal connections
A common GND is used for the external I/O terminals (START,
STOP, GO, NG, EXT_OUT, EXT_TRIG, EXT_OUT, and EXT_SMPL
terminals) and the 8855 instrument. The terminals are not
isolated. To prevent damage to the object connected to the
external I/O terminals and the 8855 instrument, wire the
terminals so that there is no difference in electrical potential
between the GND for the external I/O terminals and the GND for
the connected object.
Logic Probe Connection
The logic input and 8855 instrument share a common ground.
Therefore, if power is supplied to the measurement object of the
logic probe and to the 8855 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
8855 could be damaged. We therefore recommend the following
connection method to avoid this kind of result. Refer to Section
2.5, "Logic Probe Connection" 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 measurement object and the 8855 using the
supplied power cord.
(2) Before connecting the logic probe to the measurement
object, connect the ground of the measurement object to the
8855 ground terminal. Also in this case, power should be
supplied from the same source. Refer to Section 2.2, "Power
Supply and Ground Connections" for grounding terminal
details.
Differential Probe Connection
When using grabber clips, the 9322's maximum rated voltage
to earth is 1500 V AC or DC (CAT ll) / 600 V AC or DC (CAT lll);
when using alligator clips, it is 1000 V AC or DC (CAT ll) / 600
V AC or DC (CAT lll). To avoid electrical shock and possible
damage to the instrument, never apply voltage greater than
these limits between the input channel terminals and chassis,
or across the input of two 9322s.
Maximum input voltage is 1000 V AC/2000 V DC (CAT ll) / 600
V AC or DC (CAT lll). Attempting to measure voltage in excess
of the maximum rating could destroy the instrument and
result in personal injury or death.

────────────────────────────────────────────────────
Notes on Use
────────────────────────────────────────────────────
DANGER 10:1 and 100:1 probe connections
The maximum rated to-voltage does not change when using a
9665 10:1PROBE or a 9666 100:1PROBE. To avoid electrical
shock or damaging the 8855 instrument, make probe
connections in such a manner that the method for the probe,
and make sure the to-ground voltage does not exceed the
rated maximum.
The maximum input voltage is 1,000 V DC for the 9665
10:1PROBE, and 5,000 V DC for the 9666 100:1PROBE. (The
measurement category (overvoltage category) is the same as
that of the input modules of MEMORY HiCORDERs that use
the 9665 and the 9666. ) Do not measure voltages that exceed
the maximum input voltage, as the 8855 instrument could be
damaged and an accidents resulting in injury or death could
result.
WARNING 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.
Replacing the Input Modules
To avoid electric shock accident, before removing or
replacing an input module, confirm that the instrument is
turned off and that the connection cords 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.
Grounding the Instrument
To avoid electrical accidents and to maintain the safety
specifications of this instrument, connect the power cord only
to a 3-contact (two-conductor + ground) outlet. Refer to
Section 2.2, "Power Supply and Ground Connections."
Before Powering on
Check that the power supply is correct for the rating of the
instrument. Be careful to avoid connecting voltage improperly,
as the internal circuitry may be destroyed. (The AC fuse is
integrated in the instrument.)
Usage Precautions for the Internal MO Drive (option)
To prevent damage to the instrument, 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).

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 product. If the paper is left in
the product, paper support parts may be damaged due to
vibrations. (when the 8994 PRINTER UNIT is installed)
To avoid damage to the instrument, be sure to remove the input
modules, floppy disk, MO disk, PC card, and SCSI cable before
shipping.
Use the original packing materials when reshipping the instrument,
if possible.
Handling the CD-R
Always hold the disc by the edges, so as not to make fingerprints
on the disc or scratch the printing.
To write on the disc label surface, use a spirit-based felt pen. Do
not use a ball-point pen or hard-tipped pen, because there is a
danger of scratching 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
