We will test it before shipment. Reference Weight:0.037kg (0.08lb.) 1. product features ? complete machine patch, wave soldering, stable performance, good consistency ? with a shell, more beautiful and practical ? embedded central processor chip (MCU), smarter, lower power consumption ? power-off setting automatic memory (MCU built-in EEPROM storage unit) ? control accuracy of 0.1 degrees Celsius ? the setback of 0.1, can control the decimal (0.1-15.0) 2. technical parameters Temperature control range: -50~110°C Resolution: -9.9~99.9 when 0.1 °C Other temperature range 1 °C Temperature measurement accuracy: 0.1 °C Control accuracy: 0.1 °C Hysteresis accuracy: 0.1 °C Refresh rate: 0.5 S Display type: 0.28 inch three digital tube Input power: DC 12V Measurement input: NTC (10K 0.5%) Waterproof sensor Line length 300mm Output: 1 relay output, 5A 250VAC, 20A 16VAC Environmental requirements: -10~60°C Humidity 20%-85% Size: 47.5*18.5*31.5mm Power consumption of the whole machine: quiescent current: ≤10MA Pull-in current: ≤65MA 3. the method of use Connect the power supply and equipment to supply power to the thermostat. At this time, the temperature is displayed. Press the SET button, the display temperature will flash, press +- to set the desired temperature (press +- to quickly raise and lower) After finishing, press SET to confirm the return. At this time, the thermostat automatically performs relay on/off according to the setting! 4. the indicator light and digital tube status description Indicator light: The yellow indicator light is always on, indicating that the relay is closed. Digital tube: Display LLL is the sensor open circuit, please follow the instructions to connect the sensor; display HHH is out of the measurement range, the thermostat will force the relay to open 5. para
