How accurate is the tilt sensor in the Leica DISTO™ D330?
The accuracy of the inclination sensor in the device is ± 0.3° to the
laser beam respectively ± 0.3° to the housing of the device.
How can I check if the tilt sensor of my device is still within the
described specifications (± 0.3°)?
The tilt sensor has to be switched on. On an absolute flat surface the
first measurement has to be made. (please note angle a). Afterwards the device
has to be turned around 180° and the second measurement has to be made. (please
note angle b).
Now angle a and angle b are added up and divided by 2. If this value falls
within ± 0.3° the tilt sensor of the device is within the described
specification.
What is the angular range of the tilt sensor in the Leica DISTO™ D330?
The integral tilt sensor in the Leica DISTO™ D330 functions in the range ± 45°
and at a transverse tilt of < ± 10°. The display indicates if the tilt is in the
range > ± 50° a line appears on the display with the text max. and an info code
i 160, which means that the device is being used outside its permissible range.
If the device is held at > ± 10° transversely, a similar line appears on the
display, which indicates the transverse tilt with the text “max”. The info code
i 156 indicates that the device is tilted too much.
What units of tilts are integrated into the Leica DISTO™ D330?
You can set the Leica DISTO™ D330 to use different tilt units. The user
can select between ° and %. These can be changed in the menu.
Can the inclination sensor of a Leica DISTO™ D330 be calibrated by the user?
The user can calibrate the device’s tilt sensor. The angle sensor is
switched on by pressing the “Function key” once. Take two measurements on an
absolutely flat surface. The first measurement is taken and a note is made of
the measured angle a. The device is then turned through exactly 180°, the second
measurement is taken and a note is made of the measured angle b. The value x to
which the device must be corrected is calculated as follows:
x = - (a+b)
/2
The
calibration mode is then entered by pressing keys “Clear Off” and the “Function
key” both at the same time for 2 seconds. The correction value x can be entered
here using the “Plus” and “Minus” keys. The entered value is stored and
implemented by pressing the “Menu/=” key.
Is it possible to obtain detailed information about the measurements taken?
Yes, it is possible to obtain detailed information within the Leica DISTO™ D330
about the measurements of areas and volumes. After the measurements have been
taken (area/volume), the “Area/Volume” key must be held down and then detailed
information is shown in the display.
What accessories are recommended for the Leica DISTO™ D330?
For long distances we recommend using a tripod, even indoors. A tripod
provides additional steadiness and therefore allows accurate targeting,
especially over long distances. We particularly recommend the Leica TRI100
tripod. You will need to set within the menu button that the Leica DISTO™ D330
is now measuring from the tripod thread.
Can the Leica DISTO™ D330 also be used to measure horizontal angles?
No, the integral tilt sensor can only measure vertical angles. If the
device is held at a transverse tilt angle greater than +/-10° the display shows
an info code 156, which means that the device is required to be held level
(transversely).
What is the measuring accuracy when using the direct horizontal measuring
function?
For example, if a distance of 10m is measured at an angle of 10°, the
error on the direct horizontal distance (fd) is 9mm.
If a distance of 10m is measured at an angle of 45°, the error on the direct
horizontal distance (fd) is 37mm.
In order to have best results with indirect measurements considering the
deviation of the inclination sensor use the Leica DISTO™ D330 as follows. For
measuring distances use the instrument as flat as possible.
The
horizontal distance error (fd) and the height error (fh) can be calculated as
follows:
fd =
horizontal distance error
fh = error in height
d = measured distance
a = angle at which the distance is measured
fa = possible angular error
fd = d *
cos (a) – d * cos (a + fa)
fh= d * sin (a) – d * sin (a + fa)
Further
information and a table of measuring accuracies you can find in the FAQ
Measuring Accuracy.
Which customer segment would find the Leica DISTO™ D330 of most use for everyday
tasks?
The Leica DISTO™ D330 is a great measurement aid for a wide range of
target groups and is a superbly multi-talented device for indoor tasks. The
device is particularly suitable for the following users: architects, interior
surveyors, electricians, carpenters, kitchen installers, flooring contractors,
joiners, heating engineers, window treatment professionals, decorators and many
others.
Can the display illumination be switched off from the device?
Yes, the display illumination can be switched off in the menu.
Can the historical storage memory in the device be erased?
The historical storage memory in the device can be erased by pressing
the “Clear Off” and “Storage” keys (both pressed at the same time and held for 2
seconds).
How can I get an extra year’s warranty for the Leica DISTO™ D330?
Our standard warranty of 2 years can be extended by one additional year
if you register your device on our website http://www.disto.com/
within eight weeks of the purchase date. If the product is not registered, a two
year warranty applies
