Pay attention to the safety of electricity, enough installed capacity of power guillotine power consumption according to the oven. Selection of adequate supply conductors far-infrared oven, and should have a good grounding wire. 3. The electric contact with the mercury thermometer thermostat oven thermometer should be two wires electrical contacts were connected to the two terminals on top of the box. The other will be an ordinary mercury thermometer inserted into the exhaust valve Digital blast oven, (exhaust valve is used to proof electric contact thermometer mercury thermometer and observe the actual temperature inside use) to open the exhaust valve hole. Regulating electric contact mercury thermometer to screw fastening steel cap on the required temperature, in order to achieve the purpose of the thermostat. But care must be taken not to adjust the scale indicates the iron spin to the outside. Practice (1) dry box for sample drying melting, drying or other heating. The maximum operating temperature of 300 ℃. Oven at ambient temperature is not higher than 40 ℃, air relative humidity less than 85% under the conditions of work. (2) with a dedicated plug and socket, and with a wire grounded power cord than doubling of crude. Check before using electrical insulation properties, and note whether circuit, short circuit and leakage phenomenon. (3) on the thermometer into the box, turn on the power to adjust the thermostat knob to set the temperature oven temperature to just disconnect the AC contact switch setpoint check the thermometer readings are consistent, if different from the fine-tuning until in line with the set temperature constant temperature.
