  • Avoid unusual postures when working on ladders. Maintain firm footing and balance at all times.
  • Readings taken in the vicinity of reflective objects or surfaces, through panes of glass or similar materials can falsify the result of measurement.
  • Keep the lens and the eyepiece clean to avoid errors in measurement.
  • Use the device only within its specified limits.
  • Use the device and its accessories etc. in accordance with these instructions and in the manner intended for the particular type of device. Take the working conditions and the work to be performed into account. Use of equipment for applications other than those intended can result in hazardous situations.
  • Do not work with surveyor's staffs in the vicinity of high-voltage electricity cables.

Electromagnetic compatibility

Although the device complies with the strict requirements of the applicable directives, Hilti cannot entirely rule out the possibility of interference to the device caused by powerful electromagnetic radiation, possibly leading to incorrect operation.

Operation

Preparations at the workplace

Set up the POL 10 ⁄ 15 on a tripod to ensure its stability.

Setting up the tripod

Image alternative
  1. Push the legs of the tripod firmly into the ground.
  2. Make sure that the tripod head is approximately level.
  3. Set the POL 10 ⁄ 15 on the tripod head and tighten the locking screw on the tripod.

Leveling

Image alternative
  1. Center the bubble in the circular bubble level by turning the footscrews.
  2. Simultaneously turn footscrews (A) and (B) in opposite directions until the bubble is bisected by the centering line between (A) and (B) .
  3. Turn footscrew (C) , until the bubble is perfectly centered.
  4. Turn the POL 10 ⁄ 15 through 180° and check that the bubble remains centered.
    • If the bubble remains centered you can proceed.

Focusing the telescope

Image alternative
  1. Aim the telescope at a light-colored background.
  2. Turn the eyepiece until the crosshairs are in sharp focus.
  3. Aim the telescope at the leveling staff.
  4. Turn the focusing knob until the scale on the leveling staff is in sharp focus.

Types of work

Preparing to measure

  1. Stand the leveling staff on the measuring point.
  2. Use the open sight to aim at the leveling staff.
  3. Turn the focusing knob to bring the scale on the staff into sharp focus.
  4. Use the lateral drive to precision-aim at the leveling staff.

Measuring the height

Image alternative
  1. Prepare to measure.
  2. Read the height (H) from the middle line of the crosshairs.

Measuring the difference in height

Image alternative
  1. For better accuracy, set up the POL 10 ⁄ 15 equidistant from both measuring points.
  2. Use the leveling staff to obtain a height reading for point (A) .
  3. Use the leveling staff to obtain a height reading for point (B) .
  4. Calculate the difference in height by subtracting the reading for point (B) from the reading for point (A) .

Measuring the distance

Image alternative
  1. Prepare to measure.
  2. Read the heights at the top and bottom lines of the crosshairs and calculate the difference between the two values.
  3. Calculate the distance by multiplying the calculated difference by 100.

Measuring the angle

  1. Prepare to measure.
  2. Turn the horizontal circle to 0 .
  3. Aim the POL 10 ⁄ 15 at point B.
  4. Read the angle from the horizontal circle.

Care and maintenance

Cleaning and drying

Care
  • Blow dust off the lenses.
  • Do not touch lenses with your fingers.
  • Use only a clean, soft cloth for cleaning. If necessary, moisten the cloth slightly with pure alcohol or a little water. Do not use cleaning agents containing silicone as they can attack the plastic parts.

Hilti Measuring Systems Service

Hilti Measuring Systems Service checks the device and, if deviations from the specified accuracy are found, recalibrates it and rechecks to ensure conformity with specifications. The service certificate provides written confirmation of conformity with specifications at the time of the test. The following is recommended:
  • Choose a test/inspection interval that matches usage of the device.
  • Have testing and inspection carried out by Hilti Measuring Systems Service after exceptionally heavy usage or exposure to unusual conditions and before carrying out important work, or at least once a year.
Testing and inspection by Hilti Measuring Systems Service does not relieve the user of the obligation to check the device before and during use.

Checking and adjusting

To ensure compliance with the technical specifications, have the device checked regularly (at least before each major / relevant measuring task).

Adjusting the circular bubble level

Image alternative
  1. Set up the tripod.
  2. Level the POL 10 ⁄ 15.
  3. Turn the POL 10 ⁄ 15 through 180° and check whether the bubble in the circular bubble level is still centered.
    Result 1 / 2If the bubble is no longer centered, adjust the circular bubble level
    • Use a hex key to turn the screws on the circular bubble level until the error is half corrected.
    • Use the footscrews to level the device until the bubble in the circular bubble level is centered.
    • Again turn the POL 10 ⁄ 15 through 180 °.
    • Depending on the severity of the error, repeat these steps if necessary.
    Result 2 / 2The bubble in the circular bubble level remains centered when you turn the POL 10 ⁄ 15 round to face the opposite direction.
    The circular bubble level is correctly adjusted.

Checking the target line

Begin by checking that the circular bubble level is set correctly.
Image alternative
  1. Set up the tripod.
  2. Level the POL 10 ⁄ 15.
  3. Select two measuring points (A) and (B) and set up the POL 10 ⁄ 15 exactly midway between the two points. The distance between the two measuring points should be approx. 30 m (98 ft).
  4. Stand the leveling staffs on the measuring points.
  5. Read the heights at both points and calculate the difference in height.
  6. Set up the POL 10 ⁄ 15 at a distance of 1 m (3.3 ft) from measuring point (A) .
  7. Read the heights at both points and calculate the difference in height.
  8. Calculate the difference between the two height differences.
    • The difference is less than 3 mm (0.12 in).

Adjusting the target line

Image alternative
  1. Remove the cover from the eyepiece.
  2. Aim the POL 10 ⁄ 15 at leveling staff (B) and turn the knob to adjust the crosshairs until the difference between the height differences is less than 3 mm (0.12 in).

Transport and storage

  • Do not stow the device away when it is wet. Allow it to dry completely before stowing it away.
  • Comply with the temperature limits for storing your equipment. These limits are stated in the 'Technical data' section.
  • Check the accuracy of your equipment before using it after a long period of storage or transportation.
  • Use the Hilti case or equivalent for transporting or shipping your equipment.
