    -20° to +70° C. 1.1.6 Warranty AST 450 G-2 instruments have a warranty of two years from the invoice date. AST will replace defective parts, which arises from design errors or manufacturing faults. In case, if pyrometer is opened, disassembled or modified then the guarantees will loss.
  • Page 4 Ÿ 2.2 Application, Range and Working Principle AST 450 G-2 is digital pyrometer based on two wire technique provides digital signal processing with simple connections. Temperature measurement utilizes the fact that objects emit thermal radiation in an amount that directly corresponds to their own temperature and surface emissivity.

    Accurate Sensors Technologies 2.4 Optics The heat radiation from target object is received by the pyrometer via the lens and is then converted to an electrical signal. The measured object may be at any distance from the pyrometer. However, the farther the measured object is from the pyrometer, the larger the area that will be measured by the pyrometer.

The USB port located near to the rotary set switches is designed for use with an USB cable.
  • Page 8 Accurate Sensors Technologies 3.2.1 Example to set emissivity on the signal processor: Adjust the emissivity ε, by both switches as shown in the example. Emissivity can be adjusted between 0.05 and 1.00 in increments of 0.01. ε ε =1.00 or 100% =0.65 or 65% NOTE: - If emissivity is set to a value below 5% the pyrometer will automatically set emissivity value of 5%.The setting 00 read as ε=1.00 or 100%...
