Instruction manual
Stand
Refer to this manual for
operating procedure
details, or when problems occur.
This is the logger stand.
See the Instruction
Manual for details.
LR9504 Humidity Sensor
(Cable length: Approx. 40 mm)
LR5091 Communication Adapter
(Includes LR5000 Utility Program CD [PC
application software] and USB Cable)
Importing data to a computer requires the optional LR5091
Communication Adapter or LR5092-20 Data Collector
Display Example: Setting the
recording interval to 10 minutes.
Display the settings,
and select the setting item.
Configure the setting as
needed.
Apply the new setting contents.
(The setting items are displayed as shown under Setting Display on
page 2.)
Stop
[REC] disappears when
recording stops.
If the stop method is set
to [OFF], recording stops
automatically when
memory becomes full.
Hold the button for two seconds
while recording (while
[REC] is dis-
played).
Note: Continue pressing the button until the
[REC] indicator changes from a blinking
to off state.
Preparations
Install the battery and connect the sensor to the logger.
Installing the Battery
Press the PUSH tab as
shown, and pull the battery cover back.
Install the battery as
shown.
Align the holes in the
battery cover with the
projections on the back
of the logger.
While confirming that
there are no gaps, press
with your fingers to
close the battery cover.
When the battery is installed, the logger
turns on (there is no power switch).
Connecting a Sensor
Align the triangles on the plug
body and in front of the cable
jacks, and insert the plug
securely. (Insert the protruded
parts of the connecting cable
into the holes of the device.)
Recording
Before recording, install the logger and
perform pre-measurement inspection.
(See the Instruction manual for details.)
Start
From the Measurement display, hold
the button for two seconds.
Note: Continue pressing the button until the
[REC] indicator changes from a blink-
ing to off state.
When the blinking stops and the data count
is zeroed, recording starts.
After one second, the measurement display
reappears.
Logger memory contains the data for two recording sessions. (Be
aware that old data is erased when starting recording after two recording sessions.)
Data can be imported to a computer without stopping recording.
No measured value is displayed.
Is the sensor inserted the wrong way round?
Is the sensor inserted as far as possible?
Verify the correct plug orientation, and insert it as
far as possible.
If the values are not displayed despite these measures, the sensor and logger need to be inspected and repaired.
Please contact your dealer or Hioki representative.
Note: The maximum and minimum values are not displayed when the
recorded data count is 0.
The display is blank.
Is auto power saving enabled (set to ON)?
When enabled, the display blanks after 30 seconds of operator inactivity.
Press any button or send a communication signal to turn on the display.
The [REC] indicator disappears even though recording has not
been stopped.
Is the stop method disabled (set to OFF)?
With disabled, recording stops automatically when memory becomes full.
To record continuously until stopped by the REC/STOP button, enable the
stop method.
(In this case, old data is overwritten when the memory becomes full.)
Recorded data has disappeared.
Does recording restart after stopping?
Note that if recording is accidentally restarted after stopping, data recorded
prior to the last recording is automatically erased.
(The logger retains the data from both current and most recent prior
recording operations.)
To erase logger memory
Erase using the PC Utility program. See the Instruction manual for details.
The battery is depleted too quickly.
Are you using the battery originally supplied with the logger?
Are you using a zinc-manganese battery?
Install a new LR6 alkaline battery

Making Detailed Settings
Displaying Recorded Data
in a Table
Configure settings on the LR5000 "Data Logger" series loggers, and
on the LR5092-20 Data Collector.
The PC utility program can access settings that cannot be accessed
from the logger itself.
For example,
Set recording start/stop method and timing to start and stop
recording automatically at scheduled times
(Timer Measurements).
Measurement data can be freely scaled for display (Scaling).
Set upper and lower thresholds so that measurements outside
of the range cause [AL] (Alarm) to appear on the logger
screen (Alarm Judgment).
Add comments to measurement data.
