How the AutoHeight can help you measure your instrument height.

Measuring a total station's instrument height to ground has always been a time-consuming and cumbersome task. Considering the ongoing digitalisation of collecting, sharing and processing geospatial information in all dimensions, the conventional method of using an analogue tape has become an even bigger weakness in terms of traceable and error-free data acquisition.

AutoHeight – a convenient and innovative functionality for getting the instrument height with a simple button press. The AutoHeight functionality is available in the SOUTH N3 and N40 Series.    

AutoHeight can measure any surface and does not require a specific target. The specified accuracy down to ±2mm. The instrument height can directly be measured and applied inside the Setup app. When entering the appropriate panel, the pointer switches on automatically and the operator can see where the height will be measured to. The height will always be measured where the visible laser hits the ground.

Operation procedure:

• Press the star key, following is displayed:

• Laser plummet: Control the on/off and luminescent of Laser plummet, and the instrument height can directly be measured, choose [OK] to finish, as following image:

• When you are doing coordinate measurement, the value will show the current Inst.Ht. As following image:

In addition, a height offset can optionally be entered. This can be useful, if the laser is e.g. centered to the inner notch of a surveying nail, but the height from the upper edge is desired. In this case the notch depth can be entered as negative height offset.

Operation procedure:

• Select I.HT (instrument height) in the data Set Stn, then get into the setting page.

• Press [▼] or [▲] key to move the arrow, when move to the inputting item, input the instrument height, as following image:
