Procedures

Press the CAL key. Zero-level compensation is performed.

Explanation

Zero-level compensation

This function creates a zero input condition using the instrument’s internal circuitry
and then sets the zero level to that value. Zero-level compensation must be
performed to meet the specifications of this instrument (see chapter 17).
• Pressing the CAL key performs the zero-level compensation.
• Zero-level compensation is performed the first time a measurement is made after

changing the measurement mode, measurement range, input terminal, and input
filter.

Note

•

For making accurate measurements, we recommend 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 17) and be stable.

•

If the measurement mode, measurement range, and input filter are not changed over a long

period of time, the zero level may change due to changes in the environment surrounding the

instrument. We recommend zero-level compensation be performed in this case.
