What are the precautions to take when using an electric heat constant temperature drying oven?

1. Once powered on, the electric heating constant temperature drying oven can activate two sets of mechanisms. Simply set the control instrument's buttons to the desired temperature, and the indicator light will illuminate while the blower switch is turned on, activating the fan.

2. Once the temperature reaches the required level, the indicator light turns off, and there may be a continued rise in temperature during the start of the constant temperature phase. This is due to residual heat and typically stabilizes after about half an hour. During the constant temperature process, the temperature is automatically controlled by the thermostat, allowing for minimal management.

When maintaining a constant temperature, it is advisable to turn off one set of heating switches and leave only one set to prevent the electric heater's power from being too high, which may affect the sensitivity of temperature control.

4. One iron-case gate switch is installed in the power line, dedicated to this box, and the housing is grounded.

Before powering on, inspect the electrical performance of this box, and be mindful of any issues such as circuit breaks or leaks.

6. Once everything is prepared, place the sample inside, close the box door, and simultaneously turn the top exhaust valve.

7. The electric heating constant temperature drying oven is a non-explosion-proof drying oven; flammable and explosive items are not allowed to be placed inside.
