Using and handling the measuring tool
▶ Use the product and accessories only when they are in perfect working order.
▶ Store measuring tools out of reach of children when not in use. Do not allow persons who are not
familiar with the product or these instructions to operate it. Measuring tools are dangerous in the
hands of inexperienced persons.
▶ Measuring tools need care and attention. Check that moving parts operate satisfactorily and do
not jam, and make sure that no parts are broken or damaged in such a way that the measuring
tool might no longer function correctly. Have damaged parts repaired before using the measuring
tool. Many accidents are caused by poorly maintained measuring tools.
▶ Do not under any circumstances modify or tamper with the product. Changes or modifications not
expressly approved by Hilti may restrict the user's authorization to operate the product.
▶ Check the accuracy of the measuring tool before using it for important measurements, and if it
has been dropped or subjected to other mechanical stresses.
▶ Due to the measuring principle employed, the results of measurements can be negatively affected
by certain ambient conditions. These include, for example, the proximity of devices that produce
strong magnetic or electro-magnetic fields, vibrations and temperature changes.
▶ Rapidly changing measuring conditions can falsify the results.
▶ When the product is brought into a warm environment from very cold conditions, or vice-versa,
allow it to become acclimatized before use. Big differences in temperature can lead to incorrect
operation and incorrect results.
▶ When adapters or accessories are used, make sure they are mounted securely.
▶ The measuring tool is designed for the tough conditions of jobsite use, but as with other optical
and electrical products (e.g. binoculars, spectacles, cameras) it must be handled with care.
▶ The specified operating and storage temperatures must be observed.
2.2 Additional safety instructions
▶ Never tamper with or modify the product or accessories in any way.
▶ Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and installed
accessories are secure.
▶ Protect the measuring tool against moisture and direct sunlight.
▶ Make sure that the measuring tool is correctly acclimatized. When temperature fluctuations are strong,
acclimatization time can be up to 60 minutes. This can be the case, for example, if you keep the
measuring tool in a cold car and then perform measurement inside a warm building.
▶ Protect the measuring tool, particularly the areas of the infrared lens, speaker and microphone, against
moisture, snow, dust and dirt. The receiving lens could become fogged or dirtied and falsify the results
of measurement. Incorrect settings and other atmospheric influencing factors can lead to incorrect
measurements. Objects could be visualized with too high or too low a temperature, which can possibly
lead to a hazard on touching.
▶ High temperature differences in a thermal image can result in high temperatures being visualized in a
color associated with low temperatures. Contact with a surface visualized in this way can lead to burns.
▶ Correct temperature measurements are possible only when the set emissivity and the emissivity of the
object match. Objects could be visualized with too high or too low a temperature, which might possibly
lead to hazards on touching.
▶ Do not aim the measuring tool directly at the sun or toward CO₂ high power lasers. This can lead to
damage to the detector.
▶ Do not bring the magnet into proximity to implants or other medical devices, such as a cardiac pacemaker
or insulin pump. The magnet produces a field that can impair operation of implants or medical devices.
▶ Keep the measuring tool well away from magnetic data carriers and magnetically sensitive devices. The
effects of the magnets can cause irreversible data losses.
▶ Do not hold the product close to your ears. The sound volume of the product can cause injury and
hearing loss.
2.3 Careful handling and use of button-cell batteries
▶ Never swallow button-cell batteries. Severe internal caustic burns or death can result within 2 hours
of swallowing a button-cell battery.
▶ Make sure that button-cell batteries are inaccessible to children. Consult a physician immediately if
there is any suspicion that a button-cell battery has been swallowed or inserted into a body orifice.
▶ When replacing the button-cell battery, make sure that the correct procedure is followed. There is
a risk of explosion.
