Introduction
The Model 4000M+ does it all. Simply place the instrument in the x-ray beam, make one exposure, and it serially displays kVp
Maximum, kVp Average, kVp Effective, dose, and time. The Model 4000M+ then automatically resets for the next exposure. A CsI
photodiode pair provide the kVp measurements through five user-selectable filter pairs. This ensures optimum accuracy over the
entire diagnostic range with minimum filtration dependence. Exposure measurements are made with a parallel plate ionization chamber
located above the filter wheel. Exposure time is measured with quartz crystal accuracy. Plus, a variety of external ion chambers may
be connected for even greater flexibility.

Introduction
Features
The 4000 Toolkit for Excel is a complete software package for the 4000M+ NERO® that includes an Excel Add-In, called 4000 Add-In and Excel templates that may be used to evaluate the performance of radiographic, mammographic and fluoroscopic x-ray machines. The 4000 Add-In collects measured results from the 4000M+ NERO and places the data in the
cells of the active Excel worksheet, starting at the active worksheet cell. The 4000 Add-In also may be used to acquire and graph radiation and kV waveforms from the 4000M+ NERO as well as remotely control the 4000M+ NERO.
