Methods are groups of factory-set or user-defined settings relevant to specific
applications. If the meter is set to a factory-set 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 factory-set methods, 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.
2. Push and select ISENH3181 Settings.
3. Select Modify Current Settings.
4. Select Measurement Options and update the settings:
