7.Abnormal state
display
LCD displays “L
℃
” if the measured temperature is
below the minimum of measurement range.
LCD displays “H
℃
” if the measured temperature is
below the minimum of measurement range.
LCD displays “Er1”if the temperature measurement
circuit is abnormal (fault of SENSOR or the
temperature measurement circuit), or the ambient
temperature exceed 10
