LEICA DISTO FAQ

ALL AbOuT DISTO A8
How accurate is the inclination sensor in the Leica DISTO A8? The accuracy of the inclination
sensor to the laser beam is +/- 0.15° and +/-0.3° towards the bottom of the housing. Depending on the
measured angle and the distance the accuracy varies. E.g in measuring an angle of 10° and a distance
of 10m the horizontal mistake is 0.5cm and the mistake in height is 2.6cm. If an angle is measured of
60° and a distance of 10m the horizontal mistake is 2.3cm and the mistake in height is 1.3cm. In order
to have best results with indirect measurements considering the deviation of the inclination sensor use
the Leica DISTO A8 as follows. For measuring distances use the instrument as flat as possible. If you
need to measure heights use the instrument as steep as possible.
What different units for inclination are integrated in the Leica DISTO A8? The Leica DISTO
A8 offers a variety of commonly international used units for inclination measurements. The enduser
has the opportunity to individually choose from the following options: +/- 90.00°, +/-180.00°, +/-360.00°,
0.00%, 0.0 mm/m and 0.00 in/ft (equivalent to a pitch).
Is it also possible to measure indirect heights starting at the bottom of the object as well? Yes,
function two behind the indirect measurement key can be measured both ways. It does not matter if the
first measurement is the top of the object and then the bottom or if the first measurement is the bottom
of the object and the second one the top, both ways are possible.
What are the advantages of the calibration certificate that is included in each Leica DISTO
A8? The included calibration certificate is a great use for each customers that is using the device in
measuring applications for officials. It is standardized after EN 10201-3.1. The documented values
were measured with accredited devices in our laboratory. More information especially to the subject
recalibration you find on our website under Support/FAQs.
Is it possible to get some detailed information on the measurements I have completed? Yes,
it is possible to get detailed information of the completed measurements for the following functions
integrated in the Leica DISTO A8: area, volume, and on all functions behind the indirect measurement
key. If you press the function key you are in again for a longer time you will receive detail information of
the completed measurement.
Compared to the Leica DISTO A5 what are the new features the Leica DISTO A8 offers?
Compared with the Leica DISTO A5 on the A8 there are two new keys on the keypad. First of all
instead the optical viewfinder which was integrated in the Leica DISTO A5 the A8 now has a digital
viewfinder with 3fold digital zoom. That opens complete new measurement possibilities especially in
difficult lighting conditions. Additionally behind the indirect measurement key you will find a numerous
variety of new possibilities besides the well known Pythagoras. This is also possible due to the new
integrated inclination sensor.
What accessories are necessary to use with the Leica DISTO A8? It is strongly recommended to
use the Leica DISTO A8 with a tripod which really helps to make the measurements more accurate
by providing a stable reference for longer distances and exact aiming.
Can the Leica DISTO A8 be used for horizontal angles? No, the inclination sensor only allows
measuring vertical angles by holding the instrument with the display upwards. If you skip the instrument
by more than 20° sideways it you will get an error message on the display.
