Thermal Engineering EncyclopediaMainly designed for the calibration and maintenance of thermal instruments and systems in industrial sites, Thermal Code provides comprehensive and practical functions with simple operation. The Thermal Code uses a microcontroller as the CPU, integrating the latest large-scale digital conversion integrated circuit and large screen LCD display technology. It has output, measurement, manual, and 24VDC power distribution functions, and all four functions can work simultaneously, displaying output and measurement values as well as corresponding ITS-90 standard values (thermistor and thermocouple) on the same screen. The thermal engineering encyclopedia is equipped with a large capacity rechargeable battery, which is easy to carry and can easily complete the maintenance and calibration of thermal instruments (sensors, transmitters, display instruments, control systems) on industrial sites.

The Thermal Code is equipped with a large capacity rechargeable battery with a capacity of 10800mAh. It can be charged with an external power supply of DC12V and 1.0A for 8 hours each time. The red light on the calibration panel lights up during charging, and the green light lights up after charging is complete. While charging, the calibrator can still work normally. After a single charge, it can work normally for 8-16 hours, depending on its usage status. It has the following usage characteristics:

Precautions for using thermal engineering encyclopedia:

1. When testing and outputting, the terminal wiring must be consistent with the operation. For example, measuring voltage on the output terminal and measuring voltage on the current terminal may damage the instrument;

2. Confirm the range of each gear and do not use it beyond the range;

3. Do not use backlight when the instrument has sufficient light intensity, as this can prolong the battery life;

4. When the instrument is brought from indoors to the site and adopts automatic temperature compensation method, if the temperature difference is large, the instrument should be adapted to the site for 5 minutes to ensure that the temperature sensor inside the instrument is consistent with the ambient temperature, so as to accurately measure the ambient temperature value;

5. When outputting thermocouple signals, the set temperature should be greater than or equal to the compensated temperature, so that the output millivolt signal is positive.
