Infrared thermometer

An infrared thermometer is a thermometer which measures temperature from a portion of the thermal radiation i.e. the blackbody radiation emitted by the object being measured. The design consists of a lens to focus the infrared thermal radiation on to a detector which converts the power into an electrical signal that can be displayed on the screen of the thermometer. Through these thermometers, we can measure the temperature from a distance without any contact.

 Vertical Image Alignment control in Fluke VT04 visual IR thermometer

As we know in VT series, the heat map overlay and the visual camera are positioned vertically which will change the vertical parallax with distance to your object. To correct the parallax for near or far distance we are using vertical Image Alignment control.
To toggle a control between a near object or far object you have to push specific buttons as per your need.
  1. Press (NEAR) labelled button for a measurement distance from 15cm to 23 cm (6 in to 9 in). 
  2. Press (FAR) labelled button for a measurement distance further than 23cm/ 9in. 

The Near and Far icon shows in the upper left of the display in the figure below.
