7. r the last measurement Measurement inaccuracies The following points should be observed in order to avoid measurement errors a Q It must be ensured that the object to be measured completely fills the Infrared Thermometer monitoring area Errors can occur when measuring small objects as the unit also monitors the temperature of the surroundings as well as the object to be measured The principle of measurement requires the ambient temperature to be determined This takes place at one minute intervals or each time the unit is switched on Changes in the ambient temperature which can occur when the user holds the unit in their hand are not monitored within this time period and therefore neither of them is taken into account when determining the indicated temperature A gradual warming of the unit the lens between ambient temperature measurements can for example lead to the indicated temperature slowly falling If the emission factor for the object does not correspond to the preset value of 0 95 the temperature will not be calculated correctly Most surfaces have an emission factor in the range of 0 8 to 0 98 In general the darker and more matte the surface is the larger their emissions factor If the factor is greater the 0 95 the temperature indicated will be greater than the actual temperature of the object being measured If the factor is less then 0 9 the temperature indicated will be less than the surface temperature Poli
8. shed metals have a very low emission factor and are therefore not suitable for measuring with an infrared thermometer On the other hand affixing adhesive tape to or painting the surface will increase the emission factor and reduce the inaccuracy of the measurement It is not possible to take measurements through transparent materials glass plexiglas etc It is not possible to measure air temperatures Measurement errors can occur due to air contaminated with dust steam smoke etc 7 TROUBLESHOOTING Problem Display shows Solution The operating button has not been pressed for long enough This must be pressed for at least the duration of one measurement i e for at least 1 5 seconds Problem Display shows Err 1 Solution The ambient temperature is outside the permitted range Problem Display shows 1 Solution The measured value is outside the permitted range Problem Battery symbol illuminates Solution The batteries are dead NOTE For problems not solved please contact La Crosse Technology Maintenance 1 Changing the batteries If the battery symbol appears in the display the batteries must be changed The four button cells are accessible after opening the battery compartment at the rear of the unit The used batteries must be removed from the battery holders and replaced by new button cells of the same type Only LR44 type batteries may be used Care must be taken to ensure that the polarity is correct when i
