4Recording
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 on state.
When the blinking stops and the data count is
zeroed, recording starts.
After one second, the measurement display
reappears.
Hold the button for two seconds
while recording (while [REC] is displayed).
Note: Continue pressing the button until the
[REC] indicator changes from a blinking
to off state.
[REC] disappears when
recording stops.
If the stop method is set
to [OFF], recording stops
automatically when mem-
ory becomes full.
Logger memory contains the data for two recording sessions. (Be
aware that old data is erased when starting recording after two record-
ing sessions.)
Data can be imported to a computer without stopping recording.
Before recording, install the logger and perform
pre-measurement inspection.
(See the Instruction manual for details.)
Stop
Display Example: Setting the
recording interval to 10 minutes.

Importing data to a computer requires the optional LR5091
Communication Adapter or LR5092-20 Data Collector
Refer to this manual for
operating procedure
details, or when prob-
lems occur.
This is the logger
stand. See the Instruc-
tion Manual for details.
Example: LR9604
Confirm package contents, and prepare needed items. Install the battery and connect the cable to the logger.
No measured value is displayed.
Is the sensor plug inserted all the way in?
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 AA-size (LR6) alkaline battery.
