For this reason,the instrument is equipped with a simple temperature-controlled measurementchamber. As opposed to the LabMaster-aw, the LabTouch-aw does not offera cooling function which just allows measurement temperatures at least +2°Cbut max. +10°C above environmental (lab) temperatureFurthermore, the instrument does not have an thoroughly isolated measurementchamber. Thus the accuracy can get worse if the temperature inside the chamberis significantly higher than the environmental one, especially if the infraredsensor is covered by an installed sensor protection filter.5.2 Setting the Measurement Temperature• Press "Chamber settings" on the main menu screen and select "Temperaturecontrol afterwards, then enter the requested measurement temperaturethere. If no value is entered, the temperature control is switched-off.• A warning notice is displayed if the programmed temperature is less thanthe required 2°C above the environmental one. In addition, the displayedtemperature in the measurement screen turns red in this case and the userwill be noticed in the status bar by a respective hint.• If the environmental temperature is changing during an on-going measurementin a way that the programmed temperature can not be reached, the displayedtemperature turns red as well and the instrument will not reach stability,means the measurement can not be finished.The notice "retarded (temp)" appears below the stable indicator.• Stability is foreclosed if nominal temperature cannot be reached plus if"Stability check temperature" is activated . Retarded (temp) is displayedin this case as well.Note:The programmed temperature must be between 15°C and 30°C! |
