• The protection rating for the enclosure of this device (based on
EN60529) is *IP54.
• Although this logger is designed to resist the ingress of dust and
water, it is not entirely water- or dust-proof, so to avoid shock or damage, do not use it in a wet or dusty environment.

Avoiding Logger Damage
To avoid damage to the logger, protect it from physical shock when
transporting and handling. Be especially careful to avoid physical shock
from dropping.
Operating Precautions

CD Handling
• 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. Always wipe from the inside to the outside,
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 logger 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 logger, make sure that the insulation on the connection cables is
improperly exposed. Using the logger 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.
• Be sure to insert them wit
performance or damage from battery leakage could result.
Replace batteries only with the specified type.
• 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.
• Data and settings stored in the logger are retained even when the battery is depleted, and during battery replacement.
• The clock can keep good time for several minutes even when the battery is removed during a battery change.
• 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.
Replace batteries before extended measurement usage.
• Use only LR03 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.32)

2.1 Installing (or Replacing) the Battery
• When the battery indicator appears, settings cannot be changed
(although they can still be displayed).
• 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.)
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).

* The FET switch between the preheat signal and ground is turned on during preheating.
Connect to allow preheat signal current flow to ground.
Preheat Signal Connection Circuit Example
The preheat signal switches power to the sensor on and off. Connect the logger, sensor,
power supply, and relay as shown below.
< Typical Circuit >
Sensor Output Voltage Is Low >
< When
In the above circuit, if relay current (i) is large and sensor output voltage is low, measurement values may be affected by current flow in the connection cable. The amplitude of the effect is determined by cable resistance (about 0.2Ω) and relay current (i).
For example, if the relay current is 10 mA, the effect is 10 mA × 0.2 Ω=2 mV. When
the sensor output voltage is low, this 2 mV results in erroneous measurements. In
such cases, the effect can be minimized using the circuit on the next page.

2.2 Connecting a Connection Cable
< Isolating the Preheat Signal >
If the ground side of the power supply cannot be connected to measurement signal
ground, isolate the preheat signal as shown in the following circuit diagram. However,
in this case, a separate photocoupler power supply is required.
• When connecting a relay, transistors, and a photocoupler to the preheat signal line, be sure that the connected supply voltage and drive
current do not exceed the maximum preheat signal ratings (30 V, 50
mA).
• When using a relay, be sure to include a back-emf protection diode to
prevent damage from counter-emf when relay coil power is removed.

If the computer fails in the installation
Some computers, depending on system environments including OS and security,
can fail in the installation using the CD-R.
In such a case, download the executable program from the “Drivers, Firmware,
Software” page of Hioki’s website, and then install it again.
The data logger series LR5000 programs consists of LR5000 Utility Program and
LR5091/LR5092 Device Driver, both of which need to be installed.
If the earlier version of LR5091/LR5092 Device Driver has been installed, uninstall it before installing the latest version of program.
Ask your system administrator if installing application programs or changing system environments is prohibited for security reasons.
How to start the program?
The program starts automatically from the next Windows logon. (The icon
appears in the task tray (notification area) (p.36).)
Click the icon and click [Show Main Screen].

For setting and importing recorded data from loggers other than the
LR5000 series, use the Communication Utility program supplied with
the model 3911 or 3912 Communication Base. You can browse the
recorded data by using LR5000 Utility Program also.
