What happens if a number is visible on the display?

This is a message code. The numbers are displayed if a successful measurement could not be performed. The user can correct the measuring situation to achieve a measurement. Below you can find the spread sheet from the manual with the corrections:

No. Cause Correction
204 Calculation error Perform measurement again
220 Hardware error Contact your dealer
240 Data transfer error Repeat procedure
252 Temperature too high Let device cool down
253 Temperature too low Warm device up
255 Received signal too weak, measuring time too long Change target surface (e.g. white paper)
256 Received signal too high Change target surface (e.g. white paper)
257 Too much background light Shadow target area
258 Measurement outside of measuring range Correct range
260 Laser beam interrupted Repeat measurement


Other error messages not listed here may indicate a problem with the device. In such a case, please take the following measures:

  • Switching the device off and on again
  • Insert new batteries (please use quality batteries of known brand)
  • Repeat procedure
  • If the message appears during a measurement, select a good target at close range with little ambient light and repeat the measurement. If a measurement is possible, please check whether the previously performed measurement is at the edge of the device specification.

If the message also appears repeatedly after these measures, please contact your dealer.

How to switch off/on the beep?

The beep can be switched off (and on) with a long press simultaneously on FUNC key and Bluetooth key.

What exactly is the painter function and how does it work?

The painter function calculates the sum of several individual wall surfaces with a common height. Press FUNC key 1x to go to the area function. Press DIST key and measure the first wall length, press plus or -minus key again and measure the next wall length. The distance is automatically calculated. Repeat the procedure, until you have measured all wall lengths.

2nd measurement: Measure the wall height. The result displays automatically the wall areas, which you have selected.

Which formula stands behind the indirect measuring function Pythagoras?

In any rectangular triangle, the theorem of Pythagoras is valid: a²+b²=c². This means the other way round: c=radical of (a²+b²) or b=radical of (c²-a²). One side of the triangle can be calculated, if the other two sides are known. Therefore it is important that the DISTO measuring points are at the same level and that measurement 2 is rectangular. With a long press on the DIST-key the minimum function can be activated to get the shortest distance for measurement 2.

Can I use the Leica DISTO D2 with rechargeable batteries?

Yes, it is possible to use with standard rechargeable batteries. The more powerful the charger system is, the longer you can measure with the DISTO. We offer a powerful charger system, which is ideal to use with DISTO: Leica charger UC20 with 2 Micro AAA NiMH batteries. For more information, please check our accessories.

What accessories are recommended?

For measuring of long distances we recommend to use our Leica target plates. If the laser dot is not visible, we recommend you to wear laser glasses (GLB30).

How can I get an extra year’s warranty?

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.

What does ISO 16331-1 standard mean?

When products and services meet our expectations, we tend to take this for granted and be unaware of the role of standards. However, when standards are absent, we soon notice. We soon care when products turn out to be of poor quality or are unreliable or dangerous. An ISO Standard ensures consistent quality and reliability for a product. The range and accuracy of laser distance meters depend greatly on lighting conditions and the reflective properties of the target object. For Leica Geosystems it is important that the performance of the device is maintained not only in the test laboratory but even more so on everyday site tasks. Therefore we have worked with external experts to develop a global standard to test and specify laser distance meters and allow comparisons between devices of different manufacturers. Instruments tested in accordance with ISO 16331-1 achieve their promises. Further information can be found on our website: www.disto.com.

How can I turn on/off Bluetooth® on the device?

By pressing the Bluetooth® key for 2 seconds.

What Bluetooth® technology is integrated in the Leica DISTO D2?

The DISTO D2 has Bluetooth® SMART. The devices is working with smartphones or tablets with Bluetooth® 4.0, or are “Smart Ready”. It is also required that the operating system supports this Bluetooth® standard which is the case for iOS devices, Android devices 4.3 or higher, and Windows 8.0 or higher.

Can I send measuring data from a Leica DISTO D2 to iOS mobile devices?

Yes, the DISTO D2 can communicate with iOS mobile devices. It’s possible to send measuring data to an iPhone (iPhone 4S, iPhone 5, iPhone 5s, iPhone 5c), iPad3, iPad 4, iPad mini, iPod touch (Gen. 5). (--> Bluetooth® 4.0)

Can I send measuring data from a Leica DISTO D2 to Android devices?

Yes, the DISTO D2 can communicate also with Android devices, with operating system 4.3 or higher, and which have integrated Bluetooth 4.0. Used apps should support the corresponding Bluetooth® standard (e.g. Leica DISTO Plan).

Can I send measuring data from a Leica DISTO D2 to a Windows computer?

It is possible to send data to computers running with Windows 8.1 by using the free software Leica DISTO transfer. This free software you can download from our DISTO webpage. Windows 7 and older Windows operating systems do not support Bluetooth 4.0 and therefore do not support data transfer from the DISTO D2.

Can I send measuring data from a Leica DISTO D2 to Linux, Windows mobile, Windows RT or a Blackberry device?

No, this is not possible

Does the Leica DISTO D2 offer apps?

Yes. We offer the Leica DISTO Plan app. The app is available free of charge for iOS devices on iTunes, and for Android devices on Google Play.
