Temperature test range: 200°C to 650°C (depending on the temperature measurement performance of the matched platinum resistance thermometer)
Operating temperature range: -20 degrees Celsius to 80 degrees Celsius
Resolution: 0.1
Accuracy: The total accuracy is maintained at 0.5 (0.05% of full scale) (depending on the temperature measurement accuracy of the matched platinum resistance)
Setting method: button/serial port AT command

Command mode: AT command
Display mode: 0.36 inch digital tube display 5 red
Working voltage: DC 3.3-5v
Working current: less than 100mA
Power supply interface: Micro-USB/power hole
Data communication interface: TTL head
Platinum resistor interface type: compatible with 2-wire/3-wire/4-wire, fixed KF850 terminal
The default platinum resistance type: PT100, if you use PT1100, you need to replace the chip reference resistance inside the module
1. The thermostat supports PT100 platinum resistance by default. If you need to use PT1000 platinum resistance, you need to change the reference resistance of the thermostat from 402 ohms (4020) to 402K ohms (4021), the accuracy is 0.1%, and the package is 0805.
2. The thermostat is compatible with 2-wire/3-wire/4-wire platinum resistors by default. They are wired differently to the thermostat. You need to change a jumper on the thermostat to switch. For specific wiring methods, see the attached wiring manual
