Instruction manual

Perform step 1 stated above , then press the scroll key until the display
shows . Apply up/down key until value 0.0 is obtained. Press
scroll key for at least 3 seconds . The display will blink a moment and
a new value is obtained. Otherwise , if the display didn't blink or if
the obtained value is equal to -199.9 or 199.9, then the calibration
fails.
