Features

Ideal for Industrial Automation and Production

The 844-PE-RS is a Power Meter that allows connectivity of smart power sensors to a PC or automation systems using USB communication When the equipment space is tight or you need to control multiple power meter channels, the small size and simple interface of the 844-PE-USB is an ideal solution for system integration and automation. In addition to USB output, it also has a configurable analog output which can work in two modes raw and digital. It can reach output voltage of 0-10 Vmax.
The 844-PE-RS, can be integrated into 3rd party systems using a dedicated command set, COM-objects or used with Newport PMMmanger. PMManager™ is a powerful, easy to install, PC application software that controls the power meter and takes measurement data.  The 844-PE-USB includes a calibration certificate, a USB cable, a 2.5 mm analog output connector and a PMManager quick installation guide.

PMManager™ Application Software

PMManager™ is a powerful application software controlling and taking measurement data. It turns a PC into a laser power multi-channel analysis workstation. The PMManager software features include: extensive graphic display of data, advanced measurement processing, data logging for future review, printing of graphs and data, and the ability to connect additional devices during active measurements. The PMManager software package includes the latest PMManager user manual, the COM object manual, the available user command lists, and automation examples written in various programming languages. Please see below or the PMManager Tutorial for more details regarding its capabilities.

Directly Access All Detector Parameters

All detector parameters are directly accessible from PMManager. Major parameters are available on the detector information window, and further functions are available by clicking 'Functions' button.

Extensive Graphic Displays

Various graphics displays are available in PMManager such as Line Plot, Histogram, Bar chart, and Simulated Analog Needle. Multiple data sets on one graph or separate graphs on the same screen are possible.

Data Logging for Future Review

  • Can be displayed graphically or saved in text format 
  • Log data based on the time interval or on the number of data points 
  • Easily exported to an Excel spreadsheet

COM Object

The PMManager software package also includes a COM object, which allows system integrators to integrate the measurement expertise of Newport equipment with in-house legacy analysis packages.

Demo client applications in VB.NET 2010, VC#.NET 2010, MatLab, and LabVIEW 2013 are provided with the PMManager installation and can be found in C:\Program Files\Newport\PMManager 3.xx\Automation Examples\Com object. A console application is provided as well.

Advanced Measurement Processing

  • Power/Energy Density, Scale Factor, Normalize against a reference 
  • Multi-channel comparisons 
  • User defined mathematical equations: channels A/B, (A-B)/C etc. 
  • Log every point at up to 10 kHz with Pyro sensors in binary mode
  • Log every point at up to 1 kHz with Pyro sensors in ASCII mode
  • Position & size measurement with PEPS sensors

Calibration Report Included

Newport certifies calibration performed using standards traceable to the National Institute of Standards and Technology (NIST) and other recognized national standards laboratories. Included with your new instrument is a comprehensive calibration report. Newport also recommends recalibration every 12 months.

Regarding Legacy 841-P-USB and 842-E-USB

Please note that the new 844-PE-USB employs a completely new design and it is not compatible with the legacy 841-P-USB and 842-E-USB. However, 844-PE-USB and 841-PE-USB are compatible.
