This series of resistance furnaces are used by laboratories, industrial and mining enterprises, scientific research units for chemical analysis, physical measurement and thermocouple verification. This series of resistance furnaces must be used in conjunction with KSW type temperature controllers and K-type thermocouples to measure, indicate and automatically control the temperature of the furnace. Installation and use : 1. This series of electric furnaces do not need special installation, and can be placed on the flat floor or workbench. However, the supporting controller should avoid vibration, and the placement position should not be too close to the electric furnace to prevent overheating and affect the normal operation of the control part. 2. Insert the thermocouple from the even hole, and fill the gap between the even hole and the thermocouple with asbestos rope to prevent heat loss. 3. Uncover the temperature controller casing and connect the power cord, electric furnace wire, thermocouple and safety switch wire according to the standard. Since the controller and the electric furnace middle line are shared, the phase line and the neutral line cannot be reversed. Pay attention to the connection of the thermocouple. +" "-" is extremely irreversible, otherwise the meter will not indicate. 4. Adjust the mechanical zero point by connecting the “short†and “short†on the rear panel of the XCT-101 temperature indicator. If the compensation wire and the cold end compensator are used, the mechanical zero should be adjusted to the reference. At the temperature point, when the compensation wire is not used, the mechanical zero is adjusted to the zero position. However, the indicated temperature is the temperature difference between the measured point and the cold end of the thermocouple. 5. After checking the wiring correctly, cover the controller casing, adjust the temperature indicator pointer to the required working temperature (ie, turn the screw on the lower corner of the indicator panel), then turn on the power, and turn on the control power switch. At this time, the green light will be on. The relay starts to work, the electric furnace is energized, the ammeter is read, and the temperature indicator pointer is gradually rising, which means that the electric furnace and the temperature controller are working normally. 6. The temperature rise and constant temperature of the electric furnace are respectively indicated by red and green lights, and the red light indicates constant temperature. Maintenance and precautions : 1. When the electric furnace is used again after * use or long-term deactivation, it must be dried once. The oven time is: room temperature - 200 ° C for 2 hours, 200 ° C - 600 ° C for 2 hours, when using the furnace temperature Do not exceed the high temperature of zui to avoid burning the original heat. 2. Electric furnaces and controllers must operate at a relative humidity of no more than 85%, free of conductive dust, explosive gases, and corrosive gases that can damage metal insulation and are harmful to electronic components. 3. Regularly check whether the contact between the electric furnace and the controller is good, whether there is any stuck phenomenon when the pointer of the indicator moves, and check whether the scale error of the indicator is large by the potentiometer. 4. The working environment temperature of the controller is limited to 0°C-50°C. During transportation, the “short†and “short†wires on the rear panel of the instrument must be connected with wires to prevent vibration and damage the instrument. 5. The furnace temperature must not exceed the high temperature of zui. Shangyu Xingxing Instrument Equipment Co., Ltd. is located in Daoxu Town, Shangyu District, Shaoxing City, Zhejiang Province.
