Recording

Before recording, install the logger and perform
pre-measurement inspection.
(See the Instruction manual for details.)

[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.

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.

Troubleshooting
 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.)
Battery Status Indicator
 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.
