21.8  Performing Zero-Level Compensation
This section explains how to perform zero-level compensation.
► “Zero-Level Compensation (CAL)” in the features guide
Press SHIFT+SINGLE (CAL) to execute zero-level compensation.
Note
•  This instrument automatically performs zero-level compensation after you change the measurement 
range or input filter.
•  To make accurate measurements, we recommend that you execute zero-level compensation after 
warming up the instrument for at least 30 minutes.
•  If the measurement range and input filter remain the same for a long period of time, the zero level may 
change due to the changes in the environment. If this happens, we recommend that you execute zero-
level compensation.
•  The integration feature includes an auto calibration feature that automatically performs zero-level 
compensation.
