Operation steps and precautions of Tianling thermostat

The operation steps of Tianling constant temperature bath:

1. Add liquid medium into the tank, and the liquid level of the liquid medium should not be lower than 20mm of the worktable (fill it up as much as possible).

2. Selection of liquid medium:

A. When the working temperature is lower than 8°C, industrial alcohol is generally used as the liquid medium.

B. When the working temperature is 8°C-80°C, the liquid medium is generally pure water.

C. When the working temperature is 80°C-90°C, the liquid medium is generally a water-oil mixture.

D. When the working temperature is 90°C-100°C, the liquid medium is generally oil.

3. Connection of Circulating Chiller (skip this step if there is no water inlet and outlet):

A. To connect the internal circulation pump, just connect the water outlet to the water inlet with a hose.

B. The external circulation pump is connected to the external circulation, the water outlet is connected to the inlet of the container outside the tank with a hose, and the water inlet is connected to the outlet of the external container of the tank.

4. Plug in the power, turn on the "total power" switch, and then turn on the "power" button and the "cycle" button. (Note: The "Total Power" switch is on the back of the instrument).

5. The operation of the instrument is as follows:

A. Display instructions:

B. Instrument button description:

C. Temperature setting:

    If the working temperature is higher than the ambient temperature, press the setting function key to enter the temperature setting value setting state. The last digit of the set value is flashing. At this time, press the shift key and then the adder to set the working temperature you need, and then press the set function key twice to save the set value. At this time, the measurement shows the current tank The temperature of the liquid medium inside, and then the microcomputer enters the automatic control state.

D. If the working temperature is lower than the ambient temperature, turn on the "refrigeration" button (note: it cannot be turned on when the liquid temperature is above 40°C), and press the setting function button to enter the temperature setting value setting state. The last digit of the set value is flashing. At this time, press the shift key first and then press the minus number to set the working temperature you need, and then press the set function key twice to save the set value. At this time, the measurement shows the current tank The temperature of the liquid medium inside, and then the microcomputer enters the automatic control state.

6. Instructions for correction of value temperature and actual temperature:

In the normal display state, press and hold the "Setting" button for 3 seconds, the password prompt "Lc" will be displayed on the upper row of the display window, and the password value will be displayed on the lower row. At this time, press the plus button to enter the password "000003", and then click "Setting" ” button to enter the internal parameter setting state, and then click the “Setting” button to select the parameter to be modified. When the indicator on the upper window displays the word “Pb1”, it is temperature correction. If the actual temperature is higher than the displayed temperature If it is high, press the plus button, and if it is low, press the minus button; then press and hold the "Setting" button for 3 seconds to exit this state, and the parameter value is automatically saved. When the measured value reaches the working temperature and stabilizes for a period of time, the experiment or test can be carried out.

Precautions for use:

1. Liquid medium should be added to the tank before use. (Note: The liquid cannot contain acidity and alkalinity).

2. The power of the power supply must be greater than or equal to the total power of the instrument, and the power supply must have a good "grounding" device. The working voltage is subject to the technical parameter table.

3. The instrument should be placed in a ventilated and dry place with a distance of 300mm from obstacles on the back and sides.

4. After use, all switches are turned off, and the power plug is unplugged.
