4. OPERATING INSTRUCTIONS
• Setup the Data Logger by software before using it.
• Under the Manual mode, press and hold the button for 2s, Data Logger
start to measure, and LED indicates the function at the same time. (see
LED FLASH INDICATION for details.)
• Under the Automatic mode, you can choose the delay start time, if you
choose to delay zero second, the Data Logger will start to measure after
setup in software immediately, LED indicate the function at the same
time. (see LED FLASH INDICATION for details.)
• During measurement, the green LED indicates the working state by
flashing with the frequency setup in the software.
• If the Type-K probe is not connected to the logger, the red light will single
flash every 2 sec. It won't record the data, connect the Type-K probe to
the logger, it will start to record the data normally.
• When data logger memory full, Red LED and Green will flash every 60
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.
5. SOFTWARE OPERATION
5.1. Data logger Setup
Click on the icon on the menu bar. The Setup window will appear as
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
automatic after the delay time.
User can set a specific delay time, if the delay time is O second, the
logger will start logging immediately.
Click on the SETUP button to save changes. Press the DEFAULT button
to set the Logger to factory default condition. Press the CANCEL button
to abort the setup.
Notes: All stored data will be permanently erased when Setup is
finished. To enable you to save the data before it is lost, click Cancel
and then you need to download data.
The battery might be exhausted before logger finish specified sample
points. Always ensure that the remaining power in the battery is
sufficient for completing your logging task. If in doubt, we recommend
that you always install a fresh battery before logging critical data.

WARNING: Handle lithium batteries carefully, observe warnings on
battery casing. Dispose of in accordance with local regulations.
7. BATTERY REPLACEMENT
Only use 3.6V lithium batteries. Before replacing the battery, remove
the model from the PC. Follow diagrammatic and explanation steps
1 through 4 below:
• With a pointed object (e.g. a small screwdriver or similar), open the
casing. Lever the casing off in the direction of the arrow.
• Pull the data logger from the casing.
• Replace/Insert the battery into the battery compartment observing the
right polarity. The two displays briefly light up for control purposes
(alternating, green, yellow, green).
• Slide the data logger back into the casing until it snaps into place. Now
the data logger is ready for programing.
Note: Leaving the model plugged into the USB port for longer than
necessary will cause some of the battery capacity to be lost.
