Reference and setting method of muffle furnace temperature and constant temperature time

Many friends are consulting about the reference and setting methods of the temperature and constant temperature time of the muffle furnace. The specific methods are as follows:

If there is no constant temperature timing function:

Click the “Set” button to enter the temperature setting state, the upper row of the display window displays the prompt “SP”, and the lower row displays the temperature setting value (first place value flashes), and you can press the shift, increase, and decrease keys Modify to the required setting value; click the “Set” button again to exit this setting state, and the modified setting value will be automatically saved. In this setting state, if the muffle furnace does not press any key within 1 minute, the controller will automatically return to the normal display state.

If there is a constant temperature timer function

Click the “set” button of the muffle furnace to enter the temperature setting state, the upper row of the display window displays the prompt “SP”, the lower row displays the temperature setting value (first flashing), the modification method is the same as the above; then click ” Set” button to enter the constant temperature time setting state, the upper row of the display window displays the prompt “ST”, and the lower row displays the constant temperature time setting value (first place value flashes); then click the “set” button to exit this Setting status, the modified setting value is automatically saved.

When the constant temperature time is set to “0”, it means that the muffle furnace has no timing function, and the controller runs continuously, and the lower row of the display window displays the temperature set value; when the set time is not “0”, the lower row of the display window displays running Time or temperature setting value. When the running time is displayed, the “running time” character lights up, and when the measured temperature reaches the set temperature, the timer starts timing, the “running time” character flashes, the counted time is up, the operation ends, and the display is displayed “End” is displayed in the lower row of the window, and the buzzer will beep for 1 minute and then stop beeping. After the operation is over, long press the “decrease” key for 3 seconds to restart the operation.

If the muffle furnace temperature setting value is increased during the timing process, the meter will restart timing from 0, and if the temperature setting value is decreased, the meter will continue to keep timing.
