Operating Precautions
• Always hold the disc by the edges, so as not to make fingerprints on
the disc or scratch the printing. Never touch the recorded side of the
disc. Do not place the disc directly on anything hard.
• Do not wet the disc with volatile alcohol or water, as there is a possibility of the label printing disappearing.
• To write on the disc label surface, use a spirit-based felt pen. Do not
u
se 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 warping,
with
consequent loss of data.
• To remove dirt, dust, or fingerprints from the disc, wipe with a dry
cloth, or use a CD cleaner. Alway s wipe from the insid e to the o utside,
and do no wipe with circular movements. Never use abrasives or solvent cleaners.
• Hioki shall not be held liable for any problems with a computer system
th
at arises from the use of this CD, or for any problem related to the
purchase of a Hioki product.
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
sensor cables is undamaged and that no bare conductors are
improperly exposed. Using the instrument in such conditions
could cause an electric shock, so contact your dealer or Hioki representative for replacements.

Preparations Chapter 2

2.1 Installing (or Replacing) the Battery
•
After replacing the battery, replace the cover before using the logger .
• Battery may explode if mistreated. Do not short-circuit, recharge,
disassemble or dispose of in fire.
•
Handle and dispose of batteries in accordance with local regulations.
Do not mix old and new batteries, or different types of batteries. Also,
be careful to observe battery polarity during installation. Otherwise,
poor performance or damage from battery leakage could result.
• Data and settings stored in the logger are retained even when the battery is depleted, and during battery replacement.
• Once the battery indicator appears, operation can still continue for
about 30 seconds when the battery is removed during recording.
• Testing monitor batteries installed in the unit may possibly be weak.
Rep
lace batteries before extended measurement usage.
• Use only LR6 Alkaline batteries. Using manganese batteries may not
result in accurate measurements or proper communication with the
LR5091 Communication Adapter and LR5092-20 Data Collector.
• After installing the batteries, the following displays appear, and the
d
ate and time need to be set.
(p.38)

• When the battery indicator appears, settings cannot be changed
(although they can still be displayed).

2.1 Installing (or Replacing) the Battery
• When battery voltage is too low to operate the logger, the following
appears. Replace the battery to restore normal operation.
Battery Status Indicator
This indicator is displayed at the top right corner.
Battery charge remains. Fewer blocks within the indicator signify weaker battery charge.
Replace the discharged battery as soon as possible. (Even when the battery is removed
during recording, operation can continue for about 30 seconds.)
The battery is exhausted. In this state, recording and communication with the LR5091
Communication Adapterr and LR5092-20 Data Collector are not possible.
Using a NiMH Battery
The battery status indicator does not accurately show the remaining battery capacity
wh
en using a NiMH battery. Moreover, the battery life will vary greatly with the capacity, charging conditions and repeated uses. Please take note of these points when
using it.
The device's battery status display and battery life are based on the usage of a brandnew alkaline battery.
When the logger will not be used for long time
To avoid corrosion and damage to this instrument from battery leakage,
remove the batteries from the instrument if it is to be stored for a long
time (1 week).

2.2 Connecting a Clam p Sensor
2.2 Connecting a Clamp Sensor
Connect a clamp sensor to the logger's sensor jacks.
• Connect the clamp sensors to the instrument first, and then to
the active lines to be measured.
Observe the following to avoid electric shock
• When the clamp sensor is opened, do not allow the metal part of
the cl
amp to touch any exposed metal, or to short between two
lines, and do not use over bare conductors.
• Use the appropriate cla
the maximum voltage shown:
9695-02 Clamp On Sensor: CAT
CT6500 Clamp On Sensor: CAT
9669 Clamp On Sensor: CAT
9675 Clamp On Leak Sensor: CAT
9657-10 Clamp On Leak Sensor: CAT
Or over bare conductors.
• Clamp sensor should only be connect
a breaker, so the breaker can prevent an accident if a short circuit occurs. Connections should never be made t
side of a breaker, because unrestricted current flow could cause
a serious accident if a short circuit occurs.
• During use, do not touch the end of the sensor beyond the protective barrier.
• Maximum clamp sensor input current is as follows: (At 45 to 66 Hz)

III AC300 V
III AC600 V

and short circuits.
III AC300 V

Never exceed this limit, as doing so could result in destruction of
the instrument and personal injury or death.
• To avoid electric shock when measuring live lines, wear appropriate protective gear, such as in
and a safety helmet.
• To avoid electric shock when measuring using the
wire for transformer class B grounding work, ensure that the
grounding wire is not near high-voltage devices and wires. In a
location in which measurement is difficult because the grounding wire is near high-voltage live p
grounding wire and then perform measurement. (when using the

2.2 Connecting a Clamp Sensor
• 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.
• Do not connect or disconnect when the logger is on, or when clamped
a
round a conductor. Otherwise, the logger or clamp sensor could be
damaged.
• To avoid breaking the cables, do not bend or pull them.
• Avoid stepping on or pinching cables, which could damage the cable
lation.
insu
• To avoid damage to the instrument, protect it from physical shock
when transporting and handling. Be especially careful to avoid physical shock from dropping.
• Be careful to avoid dropping the clamp sensor or otherwise subjecting
th
em to mechanical shock, which could damage the mating surfaces
of the core and adversely affect measurement.
• Keep the clamp jaws and core slits free from foreign objects, which
co
uld interfere with clamping action.
• Keep the clamp closed when not in use, to avoid accumulating dust or
dirt on the mating core surfaces, which could interfere with clamp performance.
• Do not over-tighten the output terminal screws on the 9695-02 Clamp
On
Sensor Proper torque is about 0.5 Nm.
• To replace the output terminal screws of the 9695-02 Clamp On Sensor, use M3x5 screws with captive spring washers. Using other
scr
ews may damage the clamp sensor.
• To avoid damage to t he instrument, do not short- circuit the sensor jack
and do not input voltage to the sensor jack.
• Note that the instrument may be damaged if the applied current
exceeds the measurement range.
• When the power is turned off, do not apply current to the sensor jack.
Doing so may damage the instrument and clamp sensor.
• Note that the instrument and clamp sensor may be damaged if current
exceeding the selected measurement range is applied for a long time
• Measurements are degraded by dirt on the mating surfaces of the
clamp-on sensor, so keep the surfaces clean by gently wiping with a
soft cloth.

• When connecting the cable to the output terminals of the 9695-02
Clamp On Sensor, keep the twist as close to the terminals as possible, to minimize the effects of external magnetic fields.
• Use only the special-purpose 9219 Connection Cable to connect the
9695-02 Clamp On Sensor to the logger. (The connectors on the 9219
re solderless terminals and a BNC plug.)

Align the slots in the BNC plug on the sensor
cable with the pins in the jack on the logger.

Push and turn clockwise to lock.
To disconnect, push and turn the plug counterclockwise, then pull out.
Values are not displayed correctly if the sensor
plug is not inserted far enough.(See the 50 A range
example below.)
If values are not displayed correctly even when the
plug is inserted properly, the logger or sensor may
be damaged. Repair may be necessary.
