What preparations should be made before drying oven / oven equipment is used? The new China instruments will explain to you one by one.

1. The drying box is placed in the dry ground and worktable without any other fixtures.

2. A knife or air switch shall be installed in the power supply line for the special purpose of the box, and a conductor twice as thick as the sectional area of the power supply line shall be used as the ground wire.

3, before electrifying, check the electrical performance of this box, and pay attention to whether there is a circuit breaker or electricity leakage.

4. When everything is ready, you can put the sample in, close the door of the box, and turn the exhaust valve if necessary. The gap is about 10 mm.

5, water isolation incubator, distilled water or deionized water to the inlet, add water to the overflow mouth.

Use after power on:

6. After the power supply is connected, the heating switch can be opened, and the drying box can set the temperature dial to the required working temperature. Constant temperature incubator and water-proof incubator put the temperature setting-measuring switch in the setting, adjust the temperature setting knob to the required working temperature, and put the setting-measuring switch in the measuring. At this time, the incubator begins to heat up and the green light is on (intelligent or special requirements, instructions are attached).

7. When the temperature rises to the required working temperature, turn the green light out and then fine-tune it until the green light turns on again. At this point, the knob can be fine-tuned to the green light extinguishing place to keep the temperature constant (probably at constant temperature, the temperature will continue to rise, this is the effect of residual heat, this phenomenon is about half an hour left. Right will be stable. When the temperature in the working room is stable (the so-called "constant temperature state"), the thermostat can be adjusted slightly to improve the accuracy of temperature control. Any working temperature can be selected by this method.

8. When the oven is constant in temperature, it is necessary to turn off the high-temperature switch, leaving only one set of electric heaters to work, so as to avoid excessive power, affecting the accuracy of the constant temperature. When the working temperature is less than 150 C, only one set of heaters should be operated and the high-temperature switch should be turned off.

9. Temperature can be controlled automatically by a thermostat without manual management in the process.
