Frequently
Asked Questions
Q:
Which Disto models can be used with the upgrade kit?
A:
The kit is
specifically designed for the Leica Disto X310 or Leica Disto E7400x.
It will not
work with any other Disto model.
Q:
What is the
accuracy and repeatability of the device?
A:
Repeatability
is about 0.2 degrees.
From the
tests I made so far, accuracy is about 0.5 degrees when properly calibrated.
However, I do not have a calibrated environment to do precise accuracy
measurements.
Q:
What is the
distance range of the device?
A:
The range is
only limited by the amount of light reflected by the target. Distances above
120m (400ft) can be reached.
Q:
I see there
are 2 different Disto X310's - 80m version and 120m
version.
Does the
board work with both of these?
A:
Yes, they
differ in the Laser part only.
Q:
I will get an
order in for the battery. Do I get the one with or without the protection
circuit board?
A:
You need the
one without the circuit board.
(PGEB-NM053040,
not PGEB-NM053040-PCB)
Is there a
distributor for the non-magnetic LiPo battery in Europe?
A:
There is no
official distributor in Europe. The manufacturer ships internationally but
shipping is expensive.
The battery
cannot be shipped with the kit because of very restrictive rules for
international shipping of Lithium batteries.
It is recommended
to make collective orders within each country. The following sources are

I carefully
calibrated my DostoX2 but I do not get a delta below 0.5.
What is
wrong?
A:
In some X2
devices the acceleration sensors have a significant non-linearity. This reduces
the precision of the device.
A new version
of the firmware and calibration software allows to compensate this error. To
use it do the following:
- If your
firmware is below 2.3, use the Updater to reload it.
- Use PocketTopo Version 1.372
to do the calibration.
- During
calibration activate the “NL” option in the menu to enable calculation and
transfer of the non-linearity correction coefficients.
You can do
this with existing calibration data; there is no need to redo the calibration
measurements.
If your
device is affected you will notice a significant reduction of the delta.
Do not use
the “NL” option for DistoX1 devices or firmware versions below 2.3!
