Press SHIFT+SINGLE (CAL). Zero-level compensation is executed.
Explanation
Zero-Level Compensation
This function is used to create a zero input condition using the internal circuit of the
instrument and setting the level at that point to zero level. Zero-level compensation
must be performed to meet the specifications of this instrument (see chapter 12).
• Pressing CAL executes the zero-level compensation.
• Zero-level compensation is automatically performed after changing the
measurement range or input filter.
Note
• For making accurate measurements, it is recommended that zero-level compensation be
performed after warming up the instrument for at least 30 minutes. In addition, the ambient
temperature needs to be within the specifications (see chapter 12) and stable.
• If the measurement range and input filter are not changed over a long period of time, the zero
level may change due to the changes in the environment surrounding the instrument. It is
recommended that zero-level compensation be performed in this case.
• There are functions that automatically perform zero-level compensation during integration.
