In the Global Settings, on the Unit Settings tab, you specify length and angle units in two categories. One category is for normal use, such as for distance or angle measurement. The second category is for small values, such as residuals or standard deviations. These values are more clearly to read, if they are displayed in a smaller unit.
For example specify meter as distance measurement unit, and mm as unit for the distance standard deviation.
Large units, category 1, apply to
- Instrument Height that is displayed in the Measurement dialog box, on the Tachymeter tab, under Station Parameter.
- Height For Reduction, displayed in the Calculation Project Settings.
Small units, category 2, apply to
- Default Centring Error that is displayed in the Instrument Manager.
- Centring Error that is displayed in the Measurement dialog box, on the Tachymeter tab, under Station Parameter.
- Distance Parameter A that is displayed under Global Settings, in the Default Control Distance Settings tab.
