Eight banks are available, each capable of storing 1,000,000 values. Banks can be configured to record Flow, Temperature and Pressure (depending on the meter type) at a variety of sampling intervals. To use the software: download it (free) from CDIMeters.com to a Windows 10 device with a USB connection. Connect the device to the meter using a standard USB to micro-USB cable - initiate the software. Installer includes: The program and associated files MeterGrapherMReadMe.txt (this is it!) MeterGrapherM.xlsm - An Excel Workbook for importing and analysing files exported as .txt or .csv On first installation example files (for meters 2001 and 2043) are included. Try these to explore the capabilities - delete when no longer required. The program has labels like "Mouse Over for Graph Help". Hover over with the cursor to see details of that area. Hover over any control to see its 'Tool Tip'. MeterGrapherM USB Drivers When the meter is connected to the PC for the first time the PC will look for a USBdriver (a small program that allows the PC to communicate on that connection). If the PC is connected to the internet this process is automatic, but it may take a few minutes.

Previously: Installer: Put the exe file and a file pointing to the user data file location in Program Files (x86). This file is MGMUD.txt MGMUD.txt should not be here Attempted to put sample files in [User]\MGMPath This did not work as desired if an account with admin privilidges (rather than the end user account) was used for the installation. Version 2.6: Installer Put the exe file in Program Files (x86) Put the sample files in ProgramData\MGMPath This is accessible for reading by any user Program: ANY user MUST make folders ProgramData and AppData visible. If they ate not, In the search box (bottom left) Type %ProgramData% and press enter Type %AppData% and press enter User logs on, creates a desktop shortcut to MGM, and runs it. Program looks for a file called MGMUD.txt - if it's in: Roaming Reinstallation of V2.6 or later Do nothing ProgramFiles (x86) Installation over V2.5 or earlier Move file to Roaming Nowhere First Installation Create file in Roaming pointing to [User]\MGMPath Copy samples from ProgramData\MGMPath to [User}\MGMPath Includes a feature that allows the user to change the User File Directory If the user doesn't want files in [User]/MGMPath another location can be selected On completion of the directory change program terminates - restart for the changes to be activated No files are copied. User can copy them using File Explorer. N.B. The files are a cohrent, coordinated set Copy the whole directory - part copies will lead to Chaos and failure! If files are to be deleted use the software, not File Explorer (or Chaos will follow!) Several users on the same machine can use MGM - either with individual data file directories, or a shared one. Each user logs on and, for a shared directory, uses the File Management / Change User Data Directory option If a shared Directory is used, ensure that all users have read/write access. Users on different machines could each specify a shared network location. New edition (24th March 2022) MGM Version 2.5 Form screen positions saved for next session - improved New edition (3rd Jun 2021) MeterGrapherM Version 2.4 Minor format improvements. New edition (1st Jun 2021) MeterGrapherM Version 2.3 Venturi meter type added File Management Save Graph added Improvements to the detection of meter replugging New edition (23rd May 2021) MeterGrapherM Version 2.2 Addition of Configuration Form, Comms Form renamed Sampling and simplified. File Management changes: Screnshot added Average changed to include Day and Hour New edition (14th May 2021) MeterGrapherM Version 2.1 Further layout changes New edition (13th May 2021) MeterGrapherM Version 2.0 Help panel repositioned Scaling panel alignment corrected Scaling panel - if either or both right axis values are blank, corresponding left axis values are copied Layout changes New edition (10th May 2021) MeterGrapherM Version 1.9 Debug Info - Read All From Bank Zero - now starts unchecked Changed approach to graph drawing and scaling. The second graph always uses the right axis, so it can be independently scaled. Everything works as before, plus Vertical Axis Scaling (Click Vert. Scaling bottom right of the graph to unhide / hide). The user can enter min and max values for each axis - values are updated as the view changes. New edition (10th May 2021) MeterGrapherM Version 1.8 Bug fixed in read of Display Values - now correctly assigns Meter Type. New edition (4th May 2021) MeterGrapherM Version 1.7 Full two graph functionality. Halts graph drawing if the file has mostly invalid data. New edition (7th Apr 2021) MeterGrapherM Version 1.6 Revamp of the graph functionality Graph shows at most 64,000 points. If the sample has more it will draw every nth point in the sample, where n is calculated so that the graph has <= 64K points. (e.g. if the sample has 1M samples, n = 16) Limitation - Single graph only - for the moment New feature - Position Bars - display showing where your view is within the whole file. New buttons: - PanL and PanR - pan the current view left or right. Zoom in to a particular period (maybe an hour or a day, depending on the overall scale), then pan to see adjacent values. The graph can be panned manually - pick a point, right click, then drag Export to .txt / .csv give the user the choice - what's in the graph or whole file. The whole file option is essential if the data is going on to a user's data management system. MeterGrapherM.xlsm, the Excel Workbook that imports, checks and displays data from MGM, will accept .csv files (as well as .txt). It takes around 5 minutes to import 1M samples. But - a handy check for folks sending data on to other systems. New edition (23rd Mar 2021) MeterGrapherM Version 1.2 Error in zooming large files corrected User option to draw all points removed New edition (22nd Mar 2021) MeterGrapherM Version 1.1 Enhancement: Quick View (QV): MGM can handle large graphs, but they may take a long tome to draw. If a file has > 64K points the user has the option to draw it in Quick View. This will draw every nth point in the sample, where n is calculated so that the graph has <= 64K points. (e.g. if the sample has 1M samples, n = 16) The QV graph can be zoomed and n is recalculated - zoomed views can be saved using the File Management Zoom option. If in Quick View: Cannot always draw 2 samples on 1 graph If you have a first graph in Quick View, the option to add another is not available If you have a first graph in Show All, a second can be added, but only showing all points back / fwd buttons not available, until zoomed in to showing every point To start again drawing the current graph, double-click.
