Temperature Coefficient and Overload Errors
The internal DMM uses an AC measurement technique that periodically measures
and removes internal offset voltages when you select a different function or range.
When manual ranging to a new range in an overload condition, the internal offset
measurement may be degraded for the selected range. Typically, an additional
0.01% of range error may be introduced. This additional error will remain until the
next periodic removal (typically 15 minutes).
