DATALOGGER THERMOMETER – Product Information

The Datalogger Thermometer is a device that records temperature
data over a certain period of time. It has a measuring range
between -200°C to 1370°C and can measure four types of
thermocouple; K, J, E, and T. The device has a large memory
capacity and can store up to 32,000 temperature readings.

The device is equipped with a USB interface and comes with
Testlink SE-520 software for downloading and analyzing the recorded
data on a PC. It also has an LCD display that shows the current
temperature reading, minimum/maximum/average temperatures, and
battery status.

DATALOGGER THERMOMETER – Product Usage Instructions

Step 1: Insert the appropriate type of
thermocouple into the input socket located at the top of the
device.

Step 2: Press the ON/OFF button to turn on the
device.

Step 3: Press the MODE button to select between
recording mode or reading mode. The recording mode will start
recording the temperature data automatically with a pre-set time
interval. The reading mode will display the current temperature
reading on the LCD screen.

Step 4: The device can be set up for specific
measurement requirements by selecting options in the Setup menu.
This includes setting the recording interval, selecting
thermocouple type, setting alarms for high/low temperature
readings, etc.

Step 5: Once the recording is completed,
connect the device to a PC using the USB cable included in the
package. Download the recorded data using Testlink SE-520 software
for analysis and further processing.

Step 6: When not in use, turn off the device
and store it in a safe place.

Note: If the battery status indicator on the
LCD screen shows low battery, replace the battery with a new one
following the instructions provided in the user manual.

PC or laptop with CD-ROM drive. At least 50 MB hard disk space available to install SE520. Recommended screen resolution 1024X768 or above.
9.4 Tutorial – Quick Start to Use SE520:
Recording real time data in waveform: (1) Power on the 4 Channel Thermometer first and connect it to a PC USB port with the cable, (2) Start SE520 program. (3) If the connection is successful the panel will display
the same value as the 4 Channel Thermometer. If fail to connect the meter with PC, it will display ” No Connection ” on the panel window in SE520.
(4) Select sampling rate from Real-Time Graph window.

(5) When the connection is successful, click ” Real Time | run ” or

from main menu to

start recording real time data and there will be a waveform on the Real Time Graph

Window.

(6) Click ” Real Time | Stop ” or

to stop recording.

9.5 How to save the recorded real time data to a file?
(1) Click the graph window you want to save and the graph window will become active, then choose File | Save from main menu or click from the tool bar .

DATALOGGER THERMOMETER
(2) There will be a save dialog window for you to choose the file name and file type to save. There are three types of file format you can choose, binary file(.ghf), text file(.txt) and EXCEL format file(.csv). The .ghf file use much fewer disk space to save the data than the other two file formats, but it can only be used in SE520. Text file can be opened by SE520 and any other word processor program like word, notepad etc. EXCEL format file can be opened by SE520 and Microsoft EXCEL. Note: If decimal separator is comma in your country, this file format will be disabled, because .CSV file also use comma to be data separator. For example 78,6 will become 78 and 6 in EXCEL )

For better result, the user may close the panel window.
10. Maintenance
In order to ensure the accuracy of the thermometer for a longer period of time you should calibrate it once a year. Clean the device and the window of the display with a clean, lint-free, antistatic and dry cleaning cloth.
Do no use cleaning agents that contain carbon or benzenes, alcohol or anything similar to clean the product since these substances damage the surface of the measuring instrument. Moreover, these fumes are hazardous to health and explosive. Do not use tools with sharp edges, screwdrivers, metal brushes or anything similar to clean the device.
