How to use the Leica DISTO E7300 aka D210

• The red Dist on key displayed here switches on the instrument and the laser in a single press.
• Pressing the Clear off button for 2 seconds switches the instrument off. Also the instrument switches off automatically after 3 minutes of inactivity.

• Beep on/off – Press &  keys simultaneously for 2 seconds.
• Illumination on/off – Press  & keys simultaneously for 2 seconds.
• Keypad lock on/off – Press  &  keys simultaneously for 2 seconds to lock the keypad. To unlock,  press  within 2 seconds after switching on the device or the device switches off on its own.

This option is designed for the convenience, need and choice. You can either measure the distance from the front of the device

or from the back of the device.

  Although the default reference setting is from the rear of the instrument.

• In DISTO E7300,  key is provided on the device to switch the measurement reference point.

• To view the results press the    thrice and navigate through last 10 readings with help of    &  keys.
• To delete the memory record press  & the together for 2 seconds and the device is ready to record next 10 results.

• By pressing the    &  keys simultaneously & continuously for 2 seconds you can navigate through different units of measurements.
• They change in this order.

1. meter upto three decimal places
2. meter upto four decimal places
3. meter upto four decimal places
4. feet upto two decimal places
5. feet and inches
6. inches upto two decimal places
7. only inches

• Beam and aim the laser on the selected target with the  key.
• Pressing the  again records the measurement on device display.

* For measurements, where there is nothing obvious at the other end for the laser to reflect back, it is recommended that you use Leica branded Target plate. 

• To activate permanent measuring, aim the laser at your desired location and press the  key for 2 seconds. This will activate the continuous laser and the display would show the min and max values on the screen.
• Focus the laser on to the wall corner (for maximum measurement) or to the horizontal side (for minimum measurement) at 0° with a swaying movement as shown in the picture.
• To stop permanent/minimum-maximum measuring press  key once.

• Add / Subtract are two basic functions in E7300. The keys are displayed on the device for this application
• With the    key, the next measurement you take is added to the previous measurement.
• And with the  key, the next measurement is subtracted from the previous one.

• For measuring the area of a surface, press the Fucnction key    once and you reach the area application which appears as  on the display screen.
• Beam the laser pressing  across to the end of the surface to take the 1st reading.
• Then focusing from the same reference point take the 2nd reading by measuring the adjacent wall length. Once this process is completed the device automatically calculates the area for you.

* Adding and subtracting areas
 You can measure two separate areas and add or subtract them from each other with the help of    or  keys.

• Same way as in the area measurement, press the Fucnction key    twice and to reach the volume application which is displayed on the screen as 
• Measure the three adjacent lengths (l x b x h) using. The only thing that needs to be kept in mind is that the all measurement needs to be taken from the same reference point.
• Once this process is completed the device automatically calculates the volume on the display.

• To do so, press the Fucnction key    four times and reach the application  on the display.
• Then from the same reference point measure a. & b.
  A. Shoot the laser with the  key to the top or the highest point of the object and press the  key again to record that measurement.
  B. Same way measure the horizontal distance from the building at 0°.
• The device automatically calculates the height or the length of the building.
   

• To do so, press the Fucnction key    five times and reach the application  on the display.
• Then from the same reference point measure a., b. & c.
  A. Shoot the laser with the  key to the top or the highest point of the object and press the  key again to measure that point.
  B. Same way and from the same reference point measure the horizontal distance from the building at 0°. (perpendicular from where you are standing)
  C. Lastly aim the laser to the lowest point of the building to measure that distance.
• With all 3 calculations the device automatically calculates the height or the length of the building.
