Error message
When the measured value PV is lower than SVL, it is shown as (communication
output is -16666), indicating that the thermocouple is inversely connected, thermal resistance
short-circuit or three-wire connection is wrong, and the ambient temperature (cold end
temperature) is too low. Please check whether the sensor wiring is correct or the sensor is
damaged. When the ambient temperature is too low, the lower limit SVL can be lowered to test.
When the measured value PV is higher than SVH, it is shown as (communication
output is 18888), which indicates that the thermocouple is open circuit or the thermal resistance
is open circuit, and the actual measurement temperature is higher than the upper limit of the
range (the sensor and the heating unit do not form the same loop, resulting in long-term heating).
Please check whether the sensor is damaged and the control loop is connected correctly
