Commissioning before use of heating plate

The heating material of the heating plate is electrothermal alloy wire, its working principle is very simple, which is the basic electrothermal effect. When the electric heating plate works, the electric current passes through the electrothermal alloy wire, which will generate heat, convert electric energy into heat energy, and conduct it to the outer shell. The electric heating board is designed with insulation materials to ensure that the current of the electric heating wire will not cause safety hazards. In product design, the heating board is mostly flat and thin, with simple structure and uniform heat dissipation, which is easy to install and use. The electrothermal plate is made of stainless steel, ceramic and other materials as the outer shell. The electrothermal alloy wire is enclosed in the interior of the electrothermal plate. Therefore, it is enclosed for heating.

Heating plate is widely used for baking, drying and other temperature experiments of samples, and it is an essential tool for biology, genetics, medicine and health, environmental protection, biochemical laboratory, analysis room, teaching and scientific research. Its heating all USES the far infrared ceramic heating technology, the temperature rises quickly, the temperature is even, saves energy, is safe.

Before the use of the heating plate, the user shall carry out necessary debugging, in which:

1. Confirm that the air switch of the required power supply is single-phase and in the state of power failure. Check that the heater circuit breaker is off.

2. The exposed wire head of the power cord of the heating plate is connected to the power switch and effectively grounded. After the power switch is powered on, the indicator light under the heating plate is on. If there is no control circuit breaker in the lower frame, the electric heating plate shall be heated directly.

3. The lower frame of heating plate controls the circuit breaker from "OFF" position to "ON" direction, heating plate. Circuit breaker to "OFF" direction, electric plate stop heating.

4. Before the heating plate stops using, turn the circuit breaker to the direction of "OFF" and cut OFF the power switch of the laboratory. When the power indicator is OFF, the work stops.`
