NOTE:
1. Environment temperature for measuring the above accuracy is 20℃±2℃.
2. The output accuracy “%” is the allowance of the set range scope.
3. When measuring the TC, the allowance of cold junction compensation should be considered. The internal allowance of cold junction compensation is smaller than or equal to ±1℃.

Button Descriptions:

Set button (M)	Used for switching among menu parameters. After modifying and saving the menu, press and hold the button back to the measurement value screen.
Decrease button (S)	Used for decreasing or modifying the current flickering position. Press and hold the button to move the modification position to the right.
Increase button (Z)	Used for increasing or modifying the current flickering position. Press and hold the button to move the modification position to the left.

In the work status, press and hold the Set button for 5 seconds to display the unlock symbol (LOC); Make LOC=1 and press the Set button to enter the menu. Press the Set button to change parameters and then press the Increase or Decrease button to modify parameter values.
