Principle
The instrument consists of Thermocouple, photoelectric switch selector, amplifier, A/D converter, monolithic microcomputer, keyboard, display, Communication interface, Data storage device and cold junction compensation. The photoelectric switch selector selects the corresponding channel signal, which is amplified by the signal amplifier, and the A/D converter converts the analog signal into a digital signal and transmits it to the monolithic microcomputer for data processing. The cold junction compensation circuit performs room temperature measurement to obtain the cold junction temperature value. The measurement signal and the cold junction temperature value are processed by the monolithic microcomputer to obtain the correct Measuring temperature value and displayed on the display screen. The keyboard, Communication interface and Data storage allow data to be set up, stored and analyzed, and can also be connected to a computer for Data analysis through the Communication interface.
Applications
Lighting appliances, power tools, household appliances, motors, electric heating appliances, medicine, petroleum, chemical, metallurgy, electric power, R & D institutions
Steps
1. Connect the Thermocouple Sensor to the corresponding channel
2. Select the display interface (file list, real-time list, bar chart, Linear dispersion, etc.) through the touch screen
3. Set the Thermocouple type and parameters of each channel
4. Customize the channel name (optional)
5. Set the recording interval and file parameters
6. Start data logging and monitoring
7. Export data files through U disk or Communication interface
8. Linear dispersion analysis with built-in analysis
Notice
• Ensure that the power supply is within the range of AC85-265V
• Operating Environment Temperature 5~ 40 ℃, Humidity 20%~ 80% (no condensation)
• Note that the voltage difference between channels is up to AC/DC 350V
• Recording interval settings range from 1 second to 24 hours
• Thermocouple type needs to match the settings
• Regular error calibration
• Make sure the storage device is connected properly when exporting files
