Page 4: General Information
-20° to +70° C. 1.1.6 Warranty AST E 450C PL 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 5 Chapter - 2 Introduction The AST E450C PL is digital two color pyrometer with extended optical head which uses ratio of two adjacent wavelengths for temperature measurement of target object. It has inbuilt LCD, LED light & keypad for parameterization to provide high performance and low maintenance of non contact temperature measurement in demanding industrial environment.
- Page 6 2.2.1 Measurement of temperature is not affected by low or changing emissivity values If the value of emissivity in both colours (wavelengths) are same as like for the black body (where emissivity =1.0) or for grey body where emissivity is less than 1.0 but a constant number and the emissivity of the target would not get influenced.

- Page 16 (G) Peak Picker Setting Three Pickers are available in Pickers setting menu (Auto, tCL, Smart) & user can switch on any as per requirement, one at a time. (G1) Auto “Auto” mode is used for discontinuous measuring task, such as object being transported on a conveyer belt in such a case the maximum value for each object has to be indicated.
- Page 17 (G3) Smart If the smart picker is switched on, the highest last temperature value will always be displayed and stored. This feature is particularly useful when object temperature is not uniform across its dimension or the pyrometer is not constantly viewing an object to be measured. Smart Picker Functions Smart picker can be turn ON &...

(H)Relative energy(for two color pyrometer) The relative energy shows a signal weakening which can be caused by contaminations of the optics or a viewing window or by dust in the field of view or a too small measuring object. Relative energy shows the measured intensity compared to the intensity, a black body radiation source would have at a determined ratio temperature of the pyrometer. - Page 19 File will be stored in .xls format named as “export”. This “export.xls” file will be saved where the software is installed. To see previous record open the file by clicking on menu File open. Screen containing historical trend & historical data will appear.
- Page 20 Temperature graph of connected pyrometer is displayed on right side of the screen. This shows the measured temperature corresponding to the time. Note: After connecting the pyrometer right click on the graph screen and choose "Set to default" option from pop-up menu.
