Introduction: The electric heating sleeve uses the alkali-free glass fiber as the insulating material, and the Cr20Ni80 alloy spring device is placed therein, and the aluminum silicate cotton is insulated by the vacuum-shaped hemispherical heat insulator, the outer casing is injection-molded, and the upper cover is electrostatically sprayed. Due to the spherical heating, the heated area of the container can reach 60% or more. Temperature control adopts computer chip as the main control unit, adopts multiple digital filter circuit, fuzzy PID control algorithm, with high measurement precision, small flushing temperature, single-button touch operation, dual-screen display, internal and external thermocouple temperature measurement, controllable Silicon control output, 160-240V wide voltage power supply, and break-proof protection function, with the characteristics of fast temperature rise, high temperature, easy operation and durability, it is the most ideal instrument for precise temperature control heating test. Instructions: 1. The controller is powered on. The upper display shows “Pt”, and the lower display shows “range value” for about 3 seconds and then enters the normal display state. 2. Temperature and constant temperature time reference and setting Click the "Settings" button to enter the temperature setting state, display the window lower display prompt "SP", the upper row displays the temperature setting value (the first bit value flashes), which can be modified by the shift, increase, decrease buttons. The desired setting value; click the "Settings" button again. Enter the constant temperature time setting state, the lower display of the display window displays the prompt “St”, and the upper row displays the constant temperature time setting value (the first digit value flashes), which can be modified to the desired setting by shifting, increasing, and reducing the keys. Set the value; click the “Set” button again to exit this setting. The modified settings are automatically saved. When the constant temperature time is set to “0”, it means that there is no timing function, the controller runs continuously, and the lower display window displays the temperature setting value; when the setting time is not “0”, the lower display window displays the running time, and The last decimal number lights up. When the measured temperature reaches the set temperature, the timer starts to count, and the illuminated decimal point flashes. When the time is up, the operation ends. The lower display shows “End” and the buzzer sounds for 30 seconds. After the operation is finished, press and hold the “Reduce/Rerun” button for 3 seconds to restart the operation. 3. When the over temperature alarm occurs, the buzzer will sound continuously and the “ALM” alarm light will light. If an over temperature alarm occurs due to changing the temperature set value. The “ALM” alarm light is on, but the buzzer does not sound. 4. When the buzzer is beeping, press any key to silence. 5. If there is no key pressed within 1 minute in the setting state, the controller will automatically return to the normal display state. 6. If “----” is displayed on the upper display of the controller window, it indicates that the temperature sensor or the controller itself is faulty. Please check the temperature sensor and its wiring carefully.
