Maintenance points of laboratory electric heating mantle

Maintenance points of laboratory electric heating mantle.
The temperature control of the laboratory electric heating mantle adopts fuzzy PID control algorithm, double-screen digital display, self-tuning function, high measurement accuracy, small temperature fluctuation, single-touch operation, internal and external thermocouple temperature measurement, thyristor control output, 160- 240v wide voltage power supply, and has the function of burnout protection; digital display speed function; built-in over-temperature protection function, low speed is stable, high speed is strong. It adopts DC motor and stepless speed regulation, which makes the product more stable in performance, easier to operate and durable in use. It is an ideal stirring heater for universities, factories and research institutes.
1. The instrument should be well grounded.
2. When it is just used, white smoke and peculiar smell come out of the cover, and the color changes from white to brown to white, which is a normal phenomenon. Because the glass fiber contains oil and other compounds in the production process, it should be placed in a ventilated place. It can be used normally after disappearing in a few minutes.
3. The squeak-squeak sound when the electric heating mantle above 3000ml is used is due to the different structure of the furnace wire and related to the pulse signal of the thyristor voltage regulation, so it can be used with confidence.
4. When the liquid spills into the cover, please turn off the power quickly, put the electric heating cover in a ventilated place, and use it after drying to avoid the danger of electric leakage or electrical short circuit.
5. When not in use for a long time, please store the electric heating mantle in a dry place without corrosive gas.
6. Please do not keep warm or dry burn with empty cover.
7. When the ambient humidity is relatively high, there may be induction electricity transmitted to the shell through the insulation layer, please ensure the grounding wire and pay attention to ventilation.
8. Equipped with burnout protection function, when the thermocouple connection is not good, the display window will display “1″ or “hhhh” green light off, and the appliance will stop heating, and it needs to be checked before use.
