Methods are groups of default or user-defined settings relevant to specific applications. If
the meter is set to the default method and the Modify Current Settings option is chosen, a
prompt for a new name is shown after the changes are entered. The settings are saved with
this name to distinguish them from the default method settings, which cannot be changed.
A saved method can be used instead of multiple adjustments to the individual settings.
Changes made to a user-defined method are automatically saved with the existing name.
Multiple methods can be saved for the same probe on each meter.
1. Make sure a probe is connected to the meter.
