show temp readings in either
C or F
C/F selectable by pressing the switch S1, S1 is on the back of the meter, you will find it when you open the meter.
Note:
"----"
means probe failures (short circuit or open circuit)
sensor: supporting stainless steel waterproof package DS18B20
For the DS18B20 Sensor:
Length of Cable : 3m
Size of Stainless steel sheath:
6*50mm
Output leads: Brown(VCC), Blue (DATA), Black (GND)
Waterproof
For each lead, we use 30pcs tinning lines, which is different from other DS18B20 sensor wires, it is soft and has better oxidation resistance ability
flexibility resistance
better thermal conductivity
The DS18B20 we shoose is from DALLAS Semiconductor Corporation in the United States. It the first temperature sensor which support "bus line" interface, It has a miniaturized, low power consumption, high performance, anti-interference ability and easy to match microprocessor, etc., Compared thermocouple sensor, it can achieve high-precision temperature measurement
