The result of the area measurement is displayed in the primary display, the two previously measured values in secondary display lines 1 and 2.

Indirect Measurement

The instrument can measure distances with the Pythagorean method. This procedure facilitates in measuring distances that are difficult to access.

[note] Adhere to the prescribed sequence of measurements:

• All target points must be vertical or horizontal on the surface of the wall.
• The best results are achieved when the instrument is rotated around a fixed point (e.g. the stop bracket is fully extended and the instrument is placed against a wall).
• To take the measurement, the minimum/maximum function can be called up. The minimum value is used for measurements that must be at right-angles to the target; the maximum distance is used for all other measurements.

[note] Make sure that the first measurement and the distance to be measured are at right angles. Use the minimum/maximum function.
