Laser classification

Integrated distancemeter

The Leica DISTO™ produces a visible laser beam which emerges from the front of the instrument.

It is a Class 2 laser product in accordance with:

• IEC60825-1 : 2007 "Radiation safety of laser products"

Laser Class 2 products:

Do not stare into the laser beam or direct it towards other people unnecessarily. Eye protection is normally afforded by aversion responses including the blink reflex.

Inserting/replacing batteries

See figure {A}

1 Remove battery compartment lid and attach handstrap.

2 Insert batteries, observing correct polarity.

3 Close the battery compartment again. Replace the batteries when the symbol flashes permanently in the display.

)

Remove the batteries before any long period of non-use to avoid the danger of corrosion.

)

We recommend the usage of AA size max. 1,5V lithium batteries or rechargable NiMH batteries. The Leica DISTO™ also works

 with Alkaline batteries but the battery lifetime will be reduced.

WARNING:

This Leica DISTO™ was delivered with high quality non-rechargable lithium batteries. Wrong usage of lithium batteries can be hazardous.

Precautions:

• Please do not recharge these batteries.

• Do not mix lithium batteries with other types of batteries.

• Do not use batteries if their casing is damaged.

Changing the reference point (multifunctional endpiece)

See figure {B}

The instrument can be adapted for the following measuring situations:

• For measurements from an edge, fold out the positioning bracket until it first locks in place. See figure {C}.

Start-up 4 Leica DISTO™ D8 LCA782205a gb

• For measurements from a corner, open the positioning bracket until it locks in place, then push the positioning bracket lightly to the right to fold it out fully. See figure {D}.

A built-in sensor automatically detects the orientation of the positioning bracket and adjusts the zero point of the instrument accordingly.

Display illumination ( )

The brightness of the display has six levels of adjustment. Step 6 is the brightest and step 1 is the darkest setting.

Long range Mode ( )

Unfavourable conditions (strong sunlight or a very weak reflective target surface) may reduce the range of the device, in spite of this the long range mode allows you to take measurements over longer distances. The use of a tripod and measurement initiation by pressing the key are recommended when measurements over 30m are made over longer time periods in these conditions. (For details see Technical specifications)

)

The settings are reset when the device is switched off.

Measuring with the tripod ( )

The reference point may be adjusted to the tripod mount if the user requires a measurement from the actual mounting grommit versus the front or back of the DISTO™. To do this select the symbol in this menu item. You can switch the reference on the tripod on or off. The setting can be seen on the display .

Pressing the button starts the laser measurement. The display shows required stake out distance in the summary line between the stake out point (first a and then b) and the instrument (rear reference).

If the DISTO™ is then moved slowly along the stake out line the displayed distance decreases. The instrument starts to beep at a distance of 0.1m from the next stake out point.

The arrows in the display indicate in which direction the

DISTO™ needs to be moved in order to achieve the defined distance

(either a or b). As soon as the staking out point is reached, the symbol appears in the display.

The function can be stopped at any time by pressing the button.

Indirect measurement

The instrument can calculate distances using Pythagoras’ theorem.

This procedure is helpful, if the distance to measure can not be reached directly.

)

Make sure you adhere to the prescribed sequence of measurement:

• All target points must be in a horizontal or vertical plane.

• The best results are achieved when the instrument is rotated about a fixed point (e.g. with the positioning bracket fully folded out and the instrument placed on a wall) or the DISTO™ is mounted on a tripod.

• The minimum/maximum function can be used - see explanation in

"Measuring -> Minimum/maximum measurement". The minimum value must be used for measurements at right angles to the target; the maximum distance for all other measurements.

Press and hold down this button until the desired time delay is reached (max. 60 seconds).

Once the key is released with the laser activated, the remaining seconds until measurement (e.g. 59, 58, 57...) are displayed in a countdown. The last

5 seconds are counted down with a beep. After the last beep the measurement is taken and the value is displayed.

)

The timer can be used for all measurements.

Working with BLUETOOTH®

Switching on BLUETOOTH® / sending measurements

A quick press on the - key starts DISTO™ BLUETOOTH®. The data connection must then be established out from a Pocket PC / PC by the application software. A grey - icon will appear in the display until this has been successfully completed. BLUETOOTH® automatically switches off if the connection to the Pocket PC / PC is not established within 240 sec from when the BLUETOOTH® was switched on.

)

Whilst the first connection between the Pocket PC/PC and the

DISTO™ is being established, a prompt for the Pin-code of the DISTO™ may be displayed. In this case, enter the code 0000 into your Pocket PC/

PC.

Switching off BLUETOOTH®

BLUETOOTH® switches off as soon as the DISTO™ is switched off.

The direction keys

Eight direction keys (identified by a small arrow near the key) on the operator's keypad are used to manoeuvre the cursor. The direction keys become active when you switch to the second level (by pressing the

CN key). The distance measuring key is active in both levels. The functionality of the direction keys depends on the software used.

Transmitting the measurement

If your software supports the direction keys use them to select the appropriate position for the cursor.

Press the button briefly to transfer the value from the summary row to the pocket PC / PC.

For further details please consult your manual for the software used.

Selecting particular values in the display

The display shows a number of measurements (min., max., last measurement taken). By pressing and holding the button you can select all measurements in the display for transmitting (blue lines under the measurements). When you press the - key or the - key you can select one specific value. Once selected the measurement can be transmitted using the - key. The same selection process can be used for areas, volumes, indirect measurements and room dimensions.

During data transmission

If the data is not confirmed as being successfully received by the Pocket PC/

PC then no new measurement can be processed. The Info code "240" appears in the display if no data transmission has taken place after 2 seconds. Press the - key and repeat the measurement and then transmit it.

)

If Bluetooth transmission is limited, the PC may have Bluetooth hardware with a shorter range. In this case we recommend the usage of an external Bluetooth USB adapter of class 2.

* maximum deviation occurs under unfavourable conditions such as bright sunlight or when measuring to poorly reflecting or very rough surfaces. Measuring accuracy between 10 m and 30 m may deteriorate to approx. ± 0.025 mm/m, for distances above 30 m to ± 0.1 mm/m. In long range mode the maximum deviation from a distance of 30 m increases to +/- 0.15 mm/m.

** applies at room temperature. For the whole operating temperature range the maximum deviation increases by +/- 0.1°.

Measuring conditions

Measuring range

The range is limited to 200 m.

At night or dusk and if the target is in shadow the measuring range without target plate is increased. Use a target plate to increase the measurement range during daylight or if the target has poor reflection properties.

Target surfaces

Measuring errors can occur when measuring toward colourless liquids (e.g. water) or dust free glass, Styrofoam or similar semi-permeable surfaces.

Aiming at high gloss surfaces may deflect the laser beam and lead to measurement errors.

Against non-reflective and dark surfaces the measuring time may increase.

Care

Do not immerse the instrument in water. Wipe off dirt with a damp, soft cloth. Do not use aggressive cleaning agents or solutions. Handle the instrument as you would a telescope or camera.
