SHT－3precisionThe digital constant temperature magnetic stirrer isSHT-2An instrument with intelligent temperature control function improved on the basis of a magnetic stirrer,Set heating, sensor temperature control, LCD digital display temperature, can keep the temperature constant to ±0.1℃. The bottom left button of the dashboard is the setting button, the second left button is the shift button, the third left button is the decrease value button, and the fourth left button is the increase value button. The upper window is the measurement value display unit, and the lower window is the setting value display unit. This instrument adopts single-phase thyristor zero crossing trigger output, which has no interference to wireless equipment. It uses a computer chip as the main control unit, employs multiple filtering circuits, and automatically recovers interference,PIDControl and self-tuning functions, the product has high measurement accuracy, accurate and stable temperature control, strong anti-interference ability, simple operation, and wide adaptability.

4： Usage:

(I) Mixing

When using this instrument, first check if the random accessories are complete, then install the fixtures in order, add the solution to the beaker that needs to be stirred, place the stirrer in the beaker, and place it in the center of the tray (sleeve). Then plug in the power plug that is connected to the instrument, connect the power source, turn on the power heating switch and speed control switch, and the indicator light will light up to start working. The speed regulation is gradually adjusted from low speed to high speed, and it is not allowed to start directly at high speed to avoid the agitator not being synchronized and causing jumping. Mixing and heating can be used simultaneously or separately. When not working, the power should be cut off.

(II) Digital display constant temperature

1 Observe the entire machine panel to understand the functions of each switch, terminal, and knob.

2 Adjust the digital display in the instrument panel to the desired temperature value. （0—399℃）

3 Connect the sensors to the two terminals in front or behind the instrument according to their colors, and do not connect them in reverse, otherwise the digital value of the digital display will decrease when it heats up. And install the sensor in a position that can accurately reflect the temperature measurement required.

4 The switch is in the on position.

5 The pressure regulating knob can be turned clockwise at an appropriate angle to control the output power of the electric heater. With the automatic control of the instrument, it can achieve a considerable level of control accuracy. Some electric meters do not have this knob, such as smart meters.

6 Plug in the power, if the green light on the instrument panel is on and the indicator light is on, it means that the electric heater is heating up. If the red light on the instrument panel is on, it means that the electric heater is not heating up and the indicator light is not on. The smart meter has a green light indicating heating,Green flashing indicates temperature control,The green light goes out, indicating that the heating has stopped.

7 During initial heating, due to the thermal inertia of the electric heater, it is best to set the set value at the desired temperature80%After a few switch actions, set the set value to the desired value to avoid excessive temperature rise during startup. The smart meter can be directly set to the desired temperature.

8 On the instrumentRSTKnobs (some at the bottom of the instrument) are used to eliminate static errors. Due to the principle of time proportional control and the relationship between temperature control environment, there is often a deviation (i.e. static error) between the stable temperature display value and the required value. By adjustingRSTThe deviation can be eliminated. The adjustment action should be carried out slowly, and after stabilizing again, the two should be consistent. The smart meter does not have this knob.
