Mastercool’s 4-Way Digital Manifold Recording Function:

  • Records and stores data directly into the manifold memory
  • Records up to 24 hours of data or 15 jobs before having to download
  • Downloads data at a rate 115 kb per second (24 hrs of data = approx. 15 min of download time)
  • Uses Mastercool’s Data Logger Application to easily view data

Mastercool Data Logger Application:

  • Display data in “real time” using a USB connection, computer and software
  • Platform: Windows 2000, XP, Windows Vista and  Windows 7
  • Log Customer Name, Date and Technician’s Name
  • Recorder/Cursor Function Features
    • (1) Recorder TIME command. Record in intervals of 5, 15 min, 1, 4, 8 and 24 hrs
    • (2) Recorder ON/OFF command
    • (3) ZOOM: NORMAL, 5X or 10X. Use the zoom option to view specific data points of interest
    • (4) The Time-Line measures the selected recording time. Moving the cursor along the timeline easily displays specific plot points
  • The Data Logger program uses the Units information (Kg/cm2, BAR, Mpa, PSI, °C, and °F) contained in each data bit on the manifold and displays these units on the screen
  • Display Function Features
    • (1) Display ALL command. This enables all parameters of the Digital Manifold to be displayed simultaneously. As the line functions propagate across the screen, the “real-time” data will also be displayed digitally
    • (2) Monitor specific functions of interest. The Data Logger continues to record all the functions in the background, regardless of how many individual functions are being displayed
    • (3) Display DEEP VACUUM ONLY command. This enables only the deep vacuum readings to be displayed on the screen.
    • (4) View ANALOG GAUGES function enables the user to represent the Digital Manifold data in the form of high and low pressure analog gauges.
