Instrument Set-up
Introduction
The safety instructions (see Safety Instructions) and the user manual should be read through carefully before the product is used for the first time. The person responsible for the product must ensure that all users understand these directions and adhere to them.
⚠️ WARNING: Indicates a potentially hazardous situation or an unintended use which, if not avoided, will result in death or serious injury.
⚠️ CAUTION: Indicates a potentially hazardous situation or an unintended use which, if not avoided, may result in minor injury and/or appreciable material, financial and environmental damage.
ℹ️ INFO: Important paragraphs which must be adhered to in practice as they enable the product to be used in a technically correct and efficient manner.
Insert Batteries
To ensure reliable use, Leica Geosystems recommends using high quality Alkaline batteries. Change batteries when the [battery] symbol is flashing.
[Diagram: Steps showing how to insert batteries into the device.]
Switching ON/OFF
[Diagram: Step 1 shows pressing the ON/DIST button. Step 2 shows the device being turned OFF after pressing the CLEAR/OFF button for 2 seconds.]
Clear
[Diagram: Step 1 shows pressing CLEAR/OFF to undo the last action. Step 2 shows pressing CLEAR/OFF twice to leave the current function and go to the default operation mode.]
Message Codes
If the message "i" appears with a number, refer to the Message Codes section. Example: "i 255".
Adjusting Measuring Reference
[Diagram: Step 1 shows distance measured from the front of the device. Pressing the button for 2 seconds sets the front reference permanently. Step 2 shows distance measured from the rear of the device (standard setting).]
Multifunctional Endpiece
The orientation of the endpiece is automatically detected, and the zero point is adjusted accordingly.
[Diagram: Shows the multifunctional endpiece in different positions, such as a corner and an edge.]
Unit Setting
Press both keys simultaneously to switch between the following units: 0.000 m, 0.00 ft, 0.0000 m, 0'00" 1/32, 0.000 in, 0 in 1/32.
[Diagram: Shows the + and - buttons being pressed.]
Beep
Press both keys simultaneously to enable or disable the beep function.
[Diagram: Shows the FUNC and [Bluetooth] buttons being pressed.]
Operations
Measuring Single Distance
Aim the active [laser] at the target.
[Diagram: Step 1: Press ON/DIST. Step 2: Aim active [laser] at target. Step 3: Result displayed (e.g., 8.532 m).]
ℹ️ INFO: Target surfaces: Measuring errors can occur when measuring to colourless liquids, glass, styrofoam, or permeable surfaces, or when aiming at high gloss surfaces. Measuring time increases on dark surfaces.
Permanent / Minimum-Maximum Measuring
This function is used to measure room diagonals (maximum values) or horizontal distance (minimum values). The minimum and maximum distance measured is displayed (min, max.). The last measured value is displayed in the main line.
[Diagram: Step 1: Press ON/DIST for 2 seconds. Step 2: Device displays min/max values. Step 3: Press ON/DIST to stop permanent/minimum-maximum measuring.]
Add / Subtract
The next measurement is added to or subtracted from the previous one. The result is shown in the main line and the measured value above. This process can be repeated as required. The same process can be used for adding or subtracting areas or volumes by pressing DIST to show the result.
[Diagram: Step 1: Shows a measurement (e.g., 7.332 m). Step 2: Press + or - button. Step 3: Shows the result (e.g., 12.847 m).]
Area
1. Aim laser at first target point.
2. Aim laser at second target point.
3. Finally, measure the height for the second length to get the wall area.
ℹ️ INFO: The result is shown in the main line and the measured value above. Painter function: Press + or - after starting the first measurement. Measure and add or subtract wall lengths. Circumference is displayed.
[Diagram: Steps showing aiming at points and measuring for area calculation.]
Volume
1. Aim laser at first target point.
2. Aim laser at second target point.
3. Aim laser at third target point.
Circumference and wall area are displayed.
[Diagram: Steps showing aiming at points and measuring for volume calculation.]
Memory (last 10 results)
The last 10 values are displayed. Use the + and - buttons to navigate through the last 10 values.
[Diagram: Shows the memory display with values.]
Delete Memory
Press both keys simultaneously. The memory is completely deleted.
[Diagram: Shows the CLEAR/OFF and FUNC buttons being pressed.]
Timer (automatic release)
Adjust the delay of automatic release (max. 60 sec, standard setting = 5 sec.). Once the key is released, the remaining seconds until the result is displayed count down. Delayed release is recommended for precise aiming, especially at long distances, to avoid shaking the device when pressing the measurement key.
[Diagram: Shows setting the timer and the countdown display.]
Pythagoras (2-point)
1. Aim laser at upper point.
2. Aim laser rectangular at lower point.
ℹ️ INFO: The result is shown in the main line and the measured distance above. Pressing the measuring key for 2 sec in the function activates automatically Minimum or Maximum measurement.
[Diagram: Steps showing aiming at points for 2-point Pythagoras measurement.]
Pythagoras (3-point)
1. Aim laser at upper point.
2. Aim laser at rectangular point.
3. Aim laser at lower point.
ℹ️ INFO: The result is shown in the main line and the measured distance above. Pressing the measuring key for 2 sec in the function activates automatically Minimum or Maximum measurement.
[Diagram: Steps showing aiming at points for 3-point Pythagoras measurement.]
Stake out
1. Adjust value.
2. Approve value and start measurement.
3. Move device slowly along the stake out line. The distance to the next stake out point is displayed.
When approaching a stake out point to less than 0.1 m, the instrument starts to beep. The function can be stopped by pressing the CLEAR/OFF button.
Example: "0.240m is missing up to next 0.625m distance."
[Diagram: Steps showing the stake out process.]
Bluetooth® Smart
Activate/Deactivate [Bluetooth]
A value from the mainline is transferred to DISTO™ sketch. Use the App for [Bluetooth] data transfer.
ℹ️ INFO: [Bluetooth] Smart is always active when the device is switched on. Measurement values will be transferred automatically right after a measurement. To transfer a result from the main line, press the [Bluetooth] key. [Bluetooth] switches off as soon as the laser distance meter is switched off. The efficient and innovative [Bluetooth] Smart module (with the new [Bluetooth] standard V4.0) works together with all [Bluetooth] Smart Ready devices. All other [Bluetooth] devices do not support the energy saving [Bluetooth] Smart Module, which is integrated in the device.
