Depending on the mode you choose you may display all temperature points shown on the thermal image or you may select a narrow interval of temperature points being displayed at one time The decision of which mode to use depends on your needs and limitations From a thermal resolution standpoint you are better off working with a narrow interval of temperature points because you will be able to see very subtle temperature differences since you have more colors or gray tones to represent fewer temperature points on the other hand if you are just looking for larger temperature differences you can not work with a narrow temperature interval because important temperature values might not be displayed There are three measurement mode positions associated with this switch O NS Y Automatic Semi Automatic Manual In Automatic mode the ThermoView Ti30 imager automatically adjusts the image to show the lowest temperature value present in the thermal scene MIN and the highest July 1 2003 42 Version 1 0 SR Tel 01943 602001 WWW ISSLTD CO UK Fax 01943 816796 AS temperature value in the scene MAX The MIN and MAX values are displayed at the beginning and at the end of color scale This mode does not require any other adjustment other than properly focusing the unit Automatic mode is recommended every time the user first starts looking at a given target since the temperature limits are unknown This mode is also recommended
