The ultrasonic pulverizer must be turned off before replacing the horn.

Settings in Ultrasound Work · Power Adjustment in Ultrasound Operation In ultrasonic operation, the user only needs to press (▲) or (▼) to adjust the output power of the ultrasonic wave (press (▲) to increase power, press (▼) to decrease power) This function is used with power trimming. When the adjustment, the output power of the instrument is not stopped. After the user adjusts to the required value, the ultrasonic output can be performed. • Ultrasound stops output The user simply presses ( ) to stop the ultrasound output. Recovery settings after over-temperature protection In the non-ultrasonic working state, if over-temperature protection occurs, the user only needs to press the SET or ENTER key to set the slot temperature. In the ultrasonic working state, the user over temperature protection phenomenon must first press ( ), then press the SET or ENTER key to modify the bath temperature. Recovery setting after overcurrent protection (overcurrent protection indicates user's output power, setting is greater than the internal protection setting value) When overcurrent protection occurs, the user can restore by pressing the PR button (reduced ultrasonic output power after recovery) Otherwise, overcurrent protection will continue to occur)

Precautions

1. The temperature protection set point must be 5 °C higher than the room temperature or sample temperature. When over-temperature protection occurs, the machine stops working.

2. It is strictly forbidden to turn on when the horn is not inserted into the liquid (no load), otherwise the transducer or ultrasonic generator will be damaged.

3, ultrasonic cell pulverization on the amount of various cell disruption, length of time, power size, pending user to determine according to various cells, select the best value.

4. After a certain period of time, the end of the horn will be corroded and corroded, and it can be flattened with oil stone or trowel, otherwise it will affect the working effect.

5, the machine does not need to preheat, the use should have a good grounding.

6. In the ultrasonic crushing, the liquid temperature will rise rapidly due to the cavitation effect of the ultrasonic cell breakage in the liquid, and the user should pay more attention to the temperature of various cells. It is recommended to use multiple breaks in a short period of time (no more than 5 seconds each time), plus an ice bath for cooling. (It is recommended that the ultrasound work for 1-2 seconds, and the gap is 2-3 seconds.)

7. This machine adopts the switching power supply without power frequency transformer. Do not touch it after opening the generator casing to prevent electric shock. The instrument has reliable performance and is generally not easily damaged.

8. This machine should be placed in a place where it is dry, free of moisture, direct sunlight, and no corrosive gas.

Warning: During the work process, the varactor must be turned off before powering off. Please re-select the transducer specifications after restarting. Otherwise, the horn may be damaged.
