sec.
• As the battery power is not sufficient, red LED will flash every 60 sec for
indication.
• Press and hold the button for 2s until Red LED flashes four times, and
then logging will stop, or connect the data logger to the host and
download the data, the data logger will stop automatically.
• Data Logger data can be read time after time, the readings you are
checking are the real time measured ones. (1 to 31808 readings); if you
reset the data logger the last data will be lost.
• If the logger is logging, the Type-K probe is disconnected, the logger will
stop logging automatically.
• Without battery, the latest hours data will be lost. Other data can be read
in software after battery is installed.
• When replacing the battery, turn off the meter and open the battery
cover. Then, replace the empty battery with a new 1/2AAA 3.6V battery
and close the cover.
* To save power, the logger's LED flashing-cycle can be changed to 20s
or 30s via the supplied software.
* To save power, alarm LEDs for temperature can be disabled via the
supplied software.
* When the battery is low, all operations will be disabled automatically.
NOTE: Logging automatically stops when the battery weakens (logged
data will be retained). The supplied software is required to restart
logging and to download logged data.

shown below; descriptions for each field in the Setup windoware listed
directly below for illustration:
• The Sampling Setup field instructs the DATA LOGGER to log readings at
a specific rate. You can input specific sampling rate data at the left
Combo box and select the time unit at the right Combo box.
• The LED Flash Cycle Setup field can be set 10s/20s/30s by the user
depending on the requirement. By selecting "No Light" option, there will
be no flash there by increasing the battery life.
• The Alarm Setup field allows the user to set HIGH and LOW
temperature limits.
• There are two start methods at the Start Method field:
1. Manual: Choose this item, the user need to click the logger button to
start data logging.
2. Automatic: Choose this item the logger will start data logging
