Alarm Modes
Single Event Alarm mode: The LED immediately starts flashing red every 10 seconds
when the measured value exceeds the alarm threshold.
Cumulative Alarm mode: The LED begins flashing red only after the
average value
exceeds the alarm threshold and also after any programmed Alarm Delay time. See
Alarm Delay parameter above.
Alarm Disable (default): Alarm function disabled.
Alarm Note: The LED will continue flashing red every 10 seconds (once it is triggered by
an alarm) even when the measurement later returns to the normal range. To stop the
LED alarm, plug the logger into the PC USB port to generate a report, or power off the
logger (short press of the power button while it is not connected to the PC).
•
Alarm Limits
Select the alarm threshold ranges for air temperature, %RH, or pressure. For example,
if the temperature range is set to 2.0~8.0
o
C, when the measurement falls below 2
o
C or
exceeds 8
o
C the LED will flash red every 10 seconds.
Note
: If an alarm occurs between two logging points, the logged data will not show the
alarm but the LED may still flash red every 10 seconds, especially in Single Event alarm
mode. If desired, use the Cumulative Alarm mode to minimize this effect.

A Note On Time Zones
The logger automatically synchronizes the time zone with the connected PC when
‘SAVE’ is selected. Note: Time zone changes occurring during logging are not taken into
account.
Once all the programming is complete, press ‘SAVE’ to confirm the settings. Close the setup
window, remove the logger from the PC USB port, and start datalogging as described in the
next section.
