5.2.5.5 Auto Zero Function
The 6241A/6242 has a function for canceling Offset Drift of the AD converter. This “Auto Zero function”
periodically measures zero point and cancels drift.
When the Auto-Zero function is set to ON, Auto-zero operation takes place under the following conditions:
• More than 10 seconds have elapsed since execution of the previous Auto-zero operation and mea-
surement has been completed.
(However, Auto-zero operation is not performed when the Memory Store Operation is set to
Burst-ON.)
• When the integration time is changed.
NOTE: When Auto Zero is enabled in Pulse source mode or pulse sweep mode, it generates a base value until it
is complete.
Therefore, the time length for outputting the base value is extended. If it is inconvenient, set the
Auto-zero function to OFF.
