USER MANUAL ThermoSpot Plus Laserliner

Completely read through the operating instructions, the "Warranty and Additional Information" booklet as well as the latest information under the internet link at the end of these instructions. Follow the instructions they contain. This document must be kept in a safe place and if the laser device is passed on, this document must be passed on with it.

Function / Application The ThermoSpot Plus is an infrared thermometer with an adjustable emission coefcient that can be used for measuring the temperature of a wide range of surfaces without having to make contact with them. The instrument measures how much electromagnetic energy is emitted in the infrared wavelength range and uses this information to calculate the surface temperature. Laser radiation! Do not stare into the beam! Class 2 laser < 1 mW · 650 nm EN 60825-1:2014/AC:2017 General safety instructions – The device must only be used in accordance with its intendedpurpose and within the scope of the specications. – The measuring tools and accessories are not toys. Keep out of reach of children. – Modications or changes to the device are not permitted, this will otherwise invalidate the approval and safety specications. – Do not expose the device to mechanical stress, extreme temperatures, moisture or signicant vibration. – The device must no longer be used if one or more of its functions fail or the battery charge is weak. – Please ensure compliance with the safety regulations set out by local and national authorities with regard to the correct and proper use of the device. Safety instructions Using class 2 lasers – Attention: Do not look into the direct or reected beam. – Do not point the laser beam towards persons. – If a person‘s eyes are exposed to class 2 laser radiation, they should shut their eyes and immediately move away from the beam. – Under no circumstances should optical instruments (magnifying glass, microscope, binoculars) – Do not use the laser at eye level (1.40…1.90 m). – Tampering with (making changes to) the laser device is not permitted. – The measuring device complies with electromagnetic compatibility regulations and limit values in accordance with EMC-Directive 2014/30/EU. – Local operating restrictions – for example, in hospitals, aircraft, petrol stations or in the vicinity of people with pacemakers – may apply. Electronic devices can potentially cause hazards or interference or be subject to hazards or interference. – The measuring accuracy may be affected when working close to high voltages or high electromagnetic alternating elds.

Continuous measurement / Hold Release the button as soon as the laser circle pinpoints the measure- ment location. The measured value is held. Laser beam switched on Battery charge Hold function Measured value display Max. value during the measurement / Emission coefcient Display lighting Unit of measurement °C Set emission coefcient ON / Measure

MAX display The MAX display determines the maximum measured value within the context of a continuous measurement (keep trigger button pressed). As soon as you release the trigger button and press it again to start a new measurement, the MAX value will be reset and the instrument will start the process of recording the maxi-mum measured value all over again.

ThermoSpot Plus Setting the emission coefcient A built-in sensor head detects the material/surface-specic infrared rays emitted by every object. The level of these emissions is determined by the material‘s emission coefcient (0.01 to 1.00). After switching on for the rst time, the device is preset to an emissivity coefcient of 0.95, which is suitable for most organic materials as well as plastics, ceramics, wood, rubber and stone. For materials with different emissivity coefcients, please refer to the table under point 6.Unknown emission coefcient:Apply masking tape or black matt paint to the surface of the area whose temperature you wish to measure. Wait until the tape/paint has heated up. The temperature of the surface can then be measured with an emission coefcient of 0.95.Button pressed briey: Value +0.01Keep button pressed: Value runs through 0.01 … 1.00The emissivity coefficient last selected is set after the device is switched on. Check the emissivity coefficient setting before each measurement.

Table of emission coefcients Calibration The meter needs to be calibrated and tested on a regular basis to ensure it produces accurate measurement results. We recommend carrying out calibration once a year. Information on maintenance and care Clean all components with a damp cloth and do not use cleaning agents, scouring agents and solvents. Remove the battery(ies) before storing for longer periods. Store the device in a clean and dry place.
