Electrical characteristics: Temperature range: temperature from - 55℃to 125℃ Resolution : temperature 0.1℃ Measurement accuracy: ±0.1℃ Control precision:0.1℃ Frequency refresh:0.8S Input voltage:DC12V/24V(chance) Measuring input : DS18B20 Waterproof type sensor Output: relay 10A one road Environments requirement:temperature from - 10℃to 60℃, humidity from 20% to 85% Product size:95mm(long)*58mm(wide)*68mm(high) Power dissipation :static currentâ‰?0MA,attraction currentâ‰?0MA Instructions:The lcd showing the measured temperature, starting temperature and stop temperature at the same time. The equipment is start to work when the Status light is light on.The equipment is stop working when the Status light extinguishThe buzzer will alarm when the measured temperature is greater than highest temperature or less than lowest temperature.Button instruction:Set key: “SET ”Â? Adjusts key : â€?”orâ€?â€?Setting instruction:1.Refrigeration Mode:The refrigeration equipment will start to work if the setting temperature of start is greater than stop and the testing temperature is greater than or equal to beginning. The refrigeration equipment will stop to work if the testing temperature less than or equal to stop temperature. 2.Heating Mode:The Heating equipment will start to work if the start temperature of set is less than stop and the temperature of testing is small or equal to beginning. If the testing temperature greater than or equal to stop temperature, the Heating equipment will stop to work.3.Temperature correction mode:The system set temperature correction for positive and negative 9 degrees. Operation method:1.Power off. 2.Hold down “SET â€?buttons. 3.Power on.At this time to enter setting temperature correction."Measured temperature" position digital scintillation. Press "+" and " -" to adjust the correction temperature. The system automatic return to normal state after 10 seconds .Under normal condition showing the temperature be equal to measured temperature A plus correction temperature B.For example: Correction temperature B = -0.5â„? Actual measured temperature A= 25â„?, Then showing the temperature is 24.5 degrees.4.Set alarm mode:Boot in 3 seconds, in the " measured temperature" position display Pxx (default is P00), then press the "+" or "-" button can be set alarm mode.Alarm modes are defined as follows:P00: alarm function off (default)P01: the current temperature exceeds the starting temperature or stop temperature is 1?, the buzzer alarm.P02: the current temperature exceeds the starting temperature or stop temperature is 2?, the buzzer alarm.P03: the current temperature exceeds the starting temperature or stop temperature is 3?, the buzzer alarm.And so on, the maximum can be set to P30.5.starting temperature and stopping temperature setting method:Long press SET button 3 seconds, then the start temperature flicker. At this time press "+" or "-" button to adjust the starting temperature.Short press SET button, then the stop temperature flicker. At this time press "+" or "-" button to adjust the stop temperature.Short press SET button again, long press SET button to exit the setup mode to return to normal state or the system automatically returns to normal state after 10 seconds.
