8.3 Performing Zero-Level Compensation
Procedure
Press SHIFT+SET (CAL) to execute zero-level compensation.
Explanation
Zero-Level Compensation
Zero-level compensation is the process of creating a zero-input condition using the internal circuit of
this instrument and setting the level at that point to the zero input level. It must be performed to meet
the specifications of this instrument (see chapter 7 in the Getting Started Guide, IM WT310E-02EN).
Zero-level compensation is automatically performed when you change the measurement range.
