Add liquid medium into the tank to make the liquid level of the medium lower than the worktable 30mm. And the selection of the medium conforms to the following principles: a. When the working temperature is lower than 5 ℃, the liquid medium generally selects absolute ethanol or ethylene glycol; b. When the working temperature is 5 ~ 85 ℃, the liquid medium generally selects water; c. When the working temperature is lower than 85 ~ 95 ℃, the liquid medium can choose 15% glycerin aqueous solution;

Turn on the power supply during the booting process, turn on the "power" switch, turn on the "cycle" switch to set the temperature: press the SET button to set the temperature, the upper row of digital tubes (PV) normal temperature measurement, the lower row of digital tubes (SV) data flashes, indicating The meter enters the temperature setting state. Press the △ key to increase the set value, press the ▽ key to set the value to decrease, the temperature setting range is -5 ~ 100 ℃, continue to press the △ key or ▽ key to set the value will change quickly; finally press the SET key to confirm the setting Set the temperature, the instrument starts to work. When the above operation is completed, the instrument enters the automatic temperature control state, and the measured temperature (PV) shows the actual temperature in the tank. (The instrument often sets the temperature to 25 ℃)

The shutdown procedure turns off the "power" switch, separates the air switch, and the power is cut off.

Note 1 When using, add liquid medium into the tank, the liquid level of the medium should be about 30mm lower than the worktable, otherwise the heater will be damaged. 2 The instrument should be placed in a dry and ventilated place with no obstacles within 300mm around the instrument. 3 When the working temperature of the constant temperature bath is low, be careful not to open the upper cover and keep your hands from entering the bath to prevent frostbite. 4 After use, all switches are turned off to cut off the power. 5 The instrument should do regular cleaning work to keep the work surface and operation panel clean. 6 Always pay attention to the level of the liquid in the observation tank. When the liquid level is too low, the liquid medium should be added in time.
