(built into this unit, for monitor)

Before using the product 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 product, make sure that the insulation on
the probes is undamaged and that no bare conductors are
improperly exposed. Using the product in such conditions
could cause an electric shock, so contact your dealer or
Hioki representative for repair.

Safety Notes

______________________________________________________________

DANGE

R

This equipment is designed according to IEC 61010
Safety Standards, and has been tested for safety prior
to shipment. Incorrect measurement procedures
could result in injury or death, as well as damage to
the equipment. Please read this manual carefully and
be sure that you understand its contents before using
the equipment. The manufacturer disclaims all
responsibility for any accident or injury except that
resulting due to defect in its product.

Safety Symbols

This symbol is affixed to locations on the equipment
where the operator should consult corresponding topics
in this manual (which are also marked with the
symbol) before using relevant functions of the
equipment.
In the manual, this mark indicates explanations which it
is particularly important that the user read before using
the equipment.

Indicates DC (Direct Current).

SafetyNotes

This Instruction Manual provides information and warnings
essential for operating this equipment in a safe manner and
for maintaining it in safe operating condition. Before using
this equipment, be sure to carefully read the following
safety notes.

Safety Notes

______________________________________________________________

DANGE

R

Indicates that incorrect operation presents extreme
danger of accident resulting in death or serious injury
to the user.

WARNING

Indicates that incorrect operation presents significant
danger of accident resulting in death or serious injury
to the user.

CAUTION

Indicates that incorrect operation presents possibility
of injury to the user or damage to the equipment.

f.s.

(maximum display or scale value, or length of scale)
Signifies the maximum display (scale) value or the length
of the scale (in cases where the scale consists of unequal
increments or where the maximum value cannot be
defined).
In general, this is the range value (the value written on
the range selector or equivalent) currently in use.

rdg.

(displayed or indicated value)
This signifies the value actually being measured, i.e., the
value that is currently indicated or displayed by the
measuring instrument.

dgt.

(resolution)
Signifies the smallest display unit on a digital measuring
instrument, i.e., the value displayed when the last digit on
the digital display is "1".

The following symbols are used in this Instruction Manual
to indicate the relative importance of cautions and
warnings.

Accuracy

The specifications in this manual include figures for
"measurement accuracy" when referring to digital
measuring instruments, and for "measurement tolerance"
when referring to analog instruments.

Safety Notes

______________________________________________________________

CAT I

Secondary electrical circuits connected to an AC
electrical outlet through a transformer or similar
device.

CAT II

Primary electrical circuits in equipment connected
to an AC electrical outlet by a power cord (portable
tools, household appliances, etc.)

CAT III

Primary electrical circuits of heavy equipment
(fixed installations) connected directly to the
distribution panel, and feeders from the distribution
panel to outlets.

CAT IV

The circuit from the service drop to the service
entrance, and to the power meter and primary
overcurrent protection device (distribution panel).

Measurement categories (Overvoltage categories)

To ensure safe operation of measurement product, 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 product in an environment
designated with a higher-numbered category than that for
which the product is rated could result in a severe accident,
and must be carefully avoided.
Never use a CAT I measuring product in CAT II, III, or IV
environments. The measurement categories comply with the
Overvoltage Categories of the IEC60664 Standards.

_____________________________________________________________________

Notes on Use

______________________________________________________________

DANGE

R

To avoid short circuit and the risk of accidental injury
or death, working voltage must be under AC300 Vrms
(CAT III) for 9650 and under AC600 Vrms (CAT III) for

9651.
The maximum rated voltage to earth of clamp sensor
must be under AC300 Vrms for 9650 and under AC600
Vrms for 9651.
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.
Clamp sensor 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.

WARNING

To avoid electric shock, do not allow the product to get
wet, and do not use it when your hands are wet.

CAUTION

To avoid electric shock when measuring live lines, wear
appropriate protective gear, such as insulated rubber
gloves, boots and a safety helmet.

This product is designed for indoor use, and operates reliably from
0to50

.
Do not store or use the product where it could be exposed to
direct sunlight, high temperature or humidity, or condensation.
Under such conditions, the product may be damaged and
insulation may deteriorate so that it no longer meets
specifications.

Notes on Use

In order to ensure safe operation and to obtain maximum
performance from the unit, observe the cautions listed
below.

Effective value calculation

To calculate effective value, measurement signal is sampled
every 250 µs and operation is carried out from data with
maximum 400 points to seek effective value.

Recording instantaneous value

To record instantaneous value, calculate effective value only
oncepersetintervalandrecordinmemory.

Recording average value

To record average value, calculate effective value only once
per second and record average value of all data within
interval in memory.
After recording starts, average value within interval is
recorded, so the initial data is not recorded immediately
after recording starts but is recorded from the following
interval.

Average value recording mode records average
value within interval, so the initial data is not
recorded immediately after recording starts but
is recorded from the following interval.
For example, when measurement started at
12:00 at 1 minute intervals, the first data is data
recorded when 1 minute has passed at 12:01.

Alarm signal output terminal is an open drain
output. During signal output, signal side and
GND side are internally grounded and any other
time, it remains open. When external power
supply is supplied, alarm signal can control
relay or sequencer. Maximum rate: 30 V, 200
mA (allowable loss 200 mW)

9. Recording mode setting

With 3636-20 stand-alone, or connected together with
COMMUNICATION BASE and PC, setting is available.
Two recording mode options are instantaneous value
recording and average value recording (AV displayed).
At factory shipment setting, average value recording is
selected.

10. Alarm setting

Alarm setting is available when 3636-20,
COMMUNICATION BASE and personal computer are
connected.
Designate upper limit and lower limit value of measurement
value with personal computer to output alarm signal when
measurement value goes outside of set range. Two channels
pass individual judgment.
During signal output, AL appears on the display.
