Constant temperature incubator shaker temperature setting and setting method to improve accuracy

First, the constant temperature culture shaker temperature setting steps Press the temperature function key to display the set temperature, and then press to display the measured temperature
.

Press the parameter modification/confirmation key, then press the ∧ key to "3", then press the temperature function key, the device enters the temperature parameter setting state, the LCD display shows the temperature setting value, the SV flashes, press the ∧∨ key to change the temperature setpoint; After the temperature is set, press the parameter modification/confirmation key to confirm
.

When the device heats up and heats the output, the red LED indicator is on
.

The rear of the box is equipped with an adjustable air vent for adjusting the oxygen volume in the box and reducing the temperature starting point
.

The temperature in the box is reduced by about 3°C when opening, so please use
it flexibly as needed.

Second, improve the constant temperature culture shaker constant temperature accuracy parameter setting steps Constant temperature culture shaker has been debugged in place before leaving the factory, due to the influence of ambient temperature, or the use of temperature points, temperature control accuracy may be slightly cheaper, how to set the temperature control accuracy to the state? The correct setting of the instrument cooling coefficient is detailed in detail, which can directly improve the temperature control accuracy
of the constant temperature culture shaker.

Press the Parameter Modify/Confirm key, press the ∧ key to "9", and press the Cooling Status key again, and the instrument enters the cooling coefficient setting state SV shining
.

The cooling coefficient
can be changed by ∧∨.

After setting, press the Parameter Modify/Confirm key to confirm
.

Using the constant temperature culture shaker temperature set in the ambient temperature plus 5 °C-60 °C in the range of constant temperature, the refrigeration coefficient should be set to "2"
.

(In order to reduce the temperature starting point, the ventilation cover on the back of the instrument should be removed and the rotating window should be screwed to the open state, such as the temperature rise is too slow in autumn and winter, and the ventilation cover can be opened after the temperature reaches the set value).
)

Using a constant temperature incubator shaker temperature setting in the range of ambient temperature minus 10 °C - ambient temperature plus 5 °C, the refrigeration coefficient should be set to "0.
2" and the back ventilation cover should be closed
.

If the temperature point is in the constant temperature state of 4 °C - ambient temperature minus 10 °C, the cooling coefficient should be set to "0.
5" and the ventilation cover should be closed
.

In the process of use of the whole machine internal motor, fan and mechanical friction will produce heat, can make the actual temperature in the instrument cavity in the case of the heater is not working automatically drift up about 5 ° C, the instrument to solve this problem, in the instrument backup with ventilation holes, when the set working temperature is in the ambient temperature to the ambient temperature plus 5 ° C temperature drift range, the back of the ventilation rotating window can be rotated to the open state
.

After this operation, the temperature can be automatically drifted down to about
2 °C.

If the use temperature point is in the temperature drift range, it is necessary to start the refrigeration compressor, that is, set the refrigeration coefficient to "0.
5", start the defrosting procedure and close
the ventilation cover.
