Measurement Of Tilt And Distance; Operations With The Memory - Ht Instruments Idm70 Bedienungsanleitung

4.10. Measurement of tilt and distance

This measurement allows for an evaluation of the tilt
with respect to the horizontal by means of an internal
sensor and of the distance between two points through
trigonometric calculation. For accurate measures we
recommend using a tripod
1. With the instrument in stand-by, press the
select the desired type of reference (see § 4.2)
2. Press the

3. Position
corresponding to the value of the desired measuring
angle "" (varying between ±65° with transversal tilt
not higher than ±10°) shown on the first display and

4. The value of distance "1" is shown on the resulting
display. The value of distance "a" is shown on the
third display, calculated as: a = (1)* cos. The value
of distance "b" is shown on the second display,
calculated as: b = (1)* sen (see Fig. 12)
5. Measuring result is automatically saved in the
instrument's memory

4.11. Operations with the memory

The instrument is provided with a memory section in
which it is possible to recall measuring results. It is
possible to save up to 20 measurements, shown in
reverse order.
