Page 11: Operating Procedures
■ Levels “Level” refers to a grouping of parameters. The following table lists the operations that are possible in each of the levels, and the diagram tells how to move between levels. There are some parameters that are not displayed for certain models.
Page 12 ■ Parameters Note: 1. Some parameters are not displayed for certain models. 2. The K3MA-L will stop measurement if the level is changed to the initial setting level or the advanced-function setting level. 3. If the input range is changed, some parameters are set to default values. Therefore, set the input range first.
