Zero Measurement
Zero measurement is a function that measures analog common voltage and cancels the offset errors
of the AD converters automatically.
Execute zero measurement once after warm-up.
1. Types of zero measurement
Types of AZ data (excluding the integration time)
AZ data to be used (excluding the integration time)
2. Timing of zero measurement
Zero measurement is performed when being specified by the ZM command or menu operation
(Refer to E) MEASURE in Section 4.2.10).
Zero measurement is performed internally when the integration time or measurement function
range is changed or spot measurement is performed.
