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.
