This makes it possible to obtain the results that are not offset.
2.2.1 Mini-mold transistor / SOTs Special –(1)
Though the “Special” mode is provided for recognizing the trimmer capacitors, variable
resistors and other components, the “Power Transistor” mode (See “2.3. P-Tr” ) or the
“Special Quad.” mode (See “2.12.4. Special Quad”) are recommendable to be used for these
components. (*Please note that the operation is not covered under YAHAMA guaranty.)
