Principle
The instrument consists of Thermocouple, photoelectric switch selector, amplifier, A/D converter, monolithic microcomputer, keyboard, display, Communication interface, Data storage device, cold junction compensation and other parts. The photoelectric switch selector selects the corresponding channel signal, amplifies it through the signal amplifier, and then converts the analog signal into a digital signal through the AD converter, which is processed by the monolithic microcomputer for data processing. The cold junction compensation circuit measures the normal temperature 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 display it 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, petroleum, chemical, metallurgy, electric power, R & D institutions
Steps
1. Connect Thermocouple to the corresponding channel
2. Select the display interface through the touch screen (such as real-time list, Linear dispersion, bar chart, etc.)
3. Set the recording interval (HH: MM: SS, 1 second to 24 hours)
Step 4 Start recording data
5. Query historical Linear dispersion and alarm records through file list
6. Export Excel files using a USB stick or PC
7. Linear dispersion analysis, set the coordinate axis, translate zoom in and reduce Linear dispersion
Notice
• environmental conditions: 5~ 40 ℃, 20%~ 80% RH (no condensation)
• Power supply: AC85-265V +/- 10% 50Hz/60Hz, Power < 10W
• The voltage difference between channels can be as high as AC/DC 350V, pay attention to high voltage live measurement
• The recording interval can be adjusted arbitrarily, but the total duration is limited by the file size
• Thermocouple type and error correction can be set independently for each channel
• Alarm buzzer can be set to mute
• Modular design, users can expand the channel by themselves
