Press the left button for 2 seconds: enter the setting: first display the password parameter P230, change the password parameter P230 to P222, then you can modify the high temperature H setting and low temperature L setting.
When entering the setting, press the left button to change PXXX-Password P parameter setting; HXXX-High temperature H setting; LXXX-Low temperature L setting.
Press the left button again for 2 seconds: exit setting.
Press the center button when entering the setting: minus parameter.
Press the right button when entering the setting: increase the parameter.
Password P parameter setting:P 0---------255, change the password parameter P230 to P222, then you can modify the high temperature H setting and low temperature L setting.
High temperature H setting range: H -15------+70 degrees.
Low temperature L setting range:L -20------+65 degrees.
Measuring temperature C range:C -45------+120 degrees.
Temperature greater than +95 degrees, fault red light on, note: the temperature in the +95 ------ +120 degrees has been showing the actual temperature.
Temperature greater than +120 degrees, the sensor is considered to be short-circuited or over-temperature, the display of "E001" indicates that the sensor is short-circuited or over-temperature, the fault red light is on.
Temperature less than -46 degrees, the sensor is considered open circuit or low temperature, the display "E002" indicates that the sensor is open circuit or low temperature, the fault red light.
When the over-temperature protection switch is disconnected, the protection alarm "bHbJ" will be displayed after 3-4 seconds.
Temperature greater than or equal to the high temperature H setting range: HXXX,
