auto-tuning state, the [AT] indicator flashes, after the auto-tuning is completed, [AT] When
the indicator light stops flashing, the controller will get a better set of PID parameters, and
the parameter values will be saved automatically. In the process of system
auto-tuning, press and hold the "shift" key for 6 seconds to stop the auto-tuning program.
In the process of system self-tuning, if there is an upper deviation over-temperature alarm,
the "ALM" alarm light will not light up and the buzzer will not sound, but the heating alarm
relay will be automatically disconnected. The "Set" key is invalid during system
auto-tuning. In the process of system self-tuning, regardless of whether there is a constant
temperature time setting, the lower row of the controller display window always displays
the temperature setting value.
4.Reference and setting of temperature internal parameters
Long press the setting key for about 3 seconds, the upper row of the indicator display
window displays the password prompt "Lc", and the lower row displays the password
value. Use the increase, decrease and shift keys to modify the required password value.
Click the set button again, if the password value is incorrect, the meter will automatically
return to the normal display state; if the password value is correct, it will enter the
temperature internal parameter setting state, and then click the set button to modify each
parameter in turn. Long press the set button for 3 seconds to exit this state, and the
parameter value is automatically saved.
5.Matters needing attention:
1. The shell of the drying box must be grounded effectively to ensure safe use.
2. The drying box should be placed in a well-ventilated room, and no flammable and
explosive materials should be placed around it.
3. The drying box has no explosion-proof device, and flammable and explosive materials
are not allowed to be dried in the drying box.
4. Do not overcrowd the items in the box, and leave space to facilitate the circulation of hot
air.
5. The inside and outside of the box should always be kept clean. If it is not used for a long
