indicator to sure the power is enough and it is available to process
temperature measurement and every function operating.
B-2 Please select corresponding thermocouple type to get accrete
temperature on the display.
C. Record function operating –use as the operation below:
C-1 Reading value hold function（HOLD）
When get reading value at B-2 step, press one time to hold the
value on the display.
C-2 Maximum reading value function（MAX）
Press the key twice in the normal mode to read the maximum value.
C-3 Minimum reading value function（MIN）
