Vertical Index Error (V-Index)
The vertical circle should read
exactly 90° (100 gon) when the
line of sight is horizontal. Any
deviation from this figure is
termed vertical index error (i).
By determining the vertical index
error the electronic level is
adjusted automatically.
Determining Instrument Errors
The calibration contains the
determination of the following
instrument errors:
• Line-Of-Sight Error (Hz-
collimation)
• Vertical Index Error (V-Index)
The electronic level is
adjusted simultaneously.
