The use, maintenance and precautions of blood lysing machine

Use and maintenance of blood lysing machine

The blood dissolving machine should be placed on a firm workbench, and the environment should be kept clean and tidy, ventilated and dry, and convenient for water supply and drainage.

Before using the blood dissolving machine, first set the speed control button to the minimum position, and turn on the "oscillation switch". >Before the blood dissolving machine, first set the speed control button to the minimum position and turn on the "oscillation switch".

Pour tap water or distilled water into the water tank, the water level should be slightly higher than the inner liquid level of the plasma bag; it is forbidden to use the heater without water.

Select a constant temperature temperature: please refer to the instruction manual of the temperature control table of the blood plasma machine for details. Select the timing and set the timing knob to the "timing" or "normally open" position.

Turn on the "oscillation switch", the indicator light is on, slowly adjust the speed control button to increase to the required speed.

All switches should be closed before stopping, the timer should be set to "zero", and the power supply should be cut off.

During continuous operation, the blood dissolving machine should be checked regularly every three months: check whether there are water droplets, dirt, etc. falling on the motor and control components; check the fuses, control components and fastening screws.

The natural wear and tear of the instrument after long-term use is normal. After the instrument has been used for one year, if abnormal noise is found in the motor, the heating system is abnormal, the transmission part bearings are worn, the belt is loose or cracked, the heating temperature is abnormal, and the electronic control component fails, the company will continue to provide quality Services, to assist in processing.

Precautions for the use of blood dissolving machine

1: Usually set the water temperature, but can be turned on for a long time. When it is used, turn on the swing switch, set the frequency, and automatically swing. Turn off the swing switch when it is used up, saving electricity and reducing mechanical wear.

2. Be sure to add water to the water level before using the blood dissolving machine, and do not dry it to protect the heating tube. With the continuous increase of the starting time, the water return of the water tank gradually evaporates, please check the water level at any time (add water and change water). Ensure that the machine is operating normally.

3. Set temperature: Press the SET key to set or view the temperature set point. Press the SET key once and the characters begin to flash, indicating that the instrument enters the setting state, press the △ key to increase the value, press the △ or ▽ key, the data will change quickly, press the SET key again and the instrument returns to the normal working state. The temperature setting is complete , The heating indicator lights up.

4. Advance setting: Press the SET key for 3 seconds to enter the inner parameter setting state. The first parameter that appears and flashes is the stop advance. The advance parameter should be carefully adjusted. In order to reduce the temperature overshoot, the instrument will cut off the heating in advance when the heating output is controlled, and start heating again when the temperature drops below the advance , The output (relay) will not work within the range of the set value and advance, so that the number of relay actions can be reduced to extend the service life of the relay. Example: If the set value is 50.0℃ and the advance is 0.5, the relay will release when the meter controls heating to 49.5.0, and the relay will be closed again when the temperature drops to 50.0℃-0.5℃=49.5℃. The larger the lead, the fewer the relay action times, and the excessive lead will reduce the control accuracy. After adjusting the advance parameter, press the SET key for 3 seconds and the instrument returns to the working state. ﹙Note: The advance setting is specially set to prevent the temperature surge from being too high after the heating stops. Generally, there is no need to modify it.

5. Error correction: when confirming that the value displayed by the meter is not the correct measured value, the displayed value can be corrected. Press the SET key for 3 seconds to enter the instrument's deep menu. The first parameter that appears and flashes is E00, which is the advance amount. Press the SET key again and the flashing parameter is the error correction parameter. This parameter can be modified with the △ or ▽ key. The instrument with the correct error correction range is corrected to incorrect. It is from -9.9°C to +9.9°C, press the SET button again to exit after the correction.
