Magic Meter

Magic Meter provides a meter display with translucent background

Applications:

• Calculated results based on readings from multiple channels, such as Power= V*I

• Enlarged display

• Warnings based on font colors

Highlights

• Intelligent Channel Select: Highlight/Select a channel in WinDaq and invoke WinDaq->View->Add-ons->Magic Meter, and it will use the selected channel as its default channel  when it is not in calculated channel mode.

• Move the mouse to the left edge of the display to reveal the configuration button. 
  
  

• Click on the configuration button to adjust the setting
  
  

• Double click on the display to switch to transparent mode
• Data Window to perform the following operations
  • None: The most recent reading
  • Average: Average all readings in the data window before presenting it
  • Minimum: Display only the minimum reading within the data window
  • Maximum:  Display only the maximum reading within the data window
  • RMS:  Perform RMS for all readings within the data window
  • AC RMS:  Average all readings and use the result as offset. Remove the offset of all readings then perform RMS
  • Calculated Channel with the following features:

    • Operators include: +, -, *, /, ^

    • Functions include: abs, floor, round, log, sqrt, ceil, log10, acos, asin, atan, sin, sinh, cos, tan, cosh, tanh

    • To use the reading from a channel, use CH notation, the channel number after this should match what you see in WinDaq. For example, CH3, CH6, CHA4 and CHA7 are available in the following WinDaq configuration
      
       

    • To use the data-window derived results, use MIN, MAX, AVE, FREQ, RMS and ACRMS to represent Min, Max, Average, Frequency, RMS, and ACRMS in the expression, i.e, CH1ACRMS returns the AC_RMS reading of channel 1 in the sampling window, CH2MIN returns the minimum reading of Channel 2 inside the sampling window.

    • The calculated result is presented in the same format as WinDaq by default. If you need to change it, please follow the steps below

      • Run MagicMeter then exit

      • Open MagicMeter.ini, you will find an entry like UserFormat=

      • Change it to UserFormat=0.00, which represents two digits after the decimal point

      • When you run MagicMeter again, it will use the new display format

    • The math equation must be valid even you don't plan to use it now

• Programmable palette for better visual effect when superimposing magic meter to Windaq. 

  • The background should match WinDaq's background

  • Foreground should match WinDaq's background if only warning display is needed to capture attention

• Limitations

  • Although the meter appears to embed inside WinDaq, it is NOT. When you move WinDaq's window around or add/subtract channels, it will NOT follow your action. 

  • The display is right-justified to align the units all the time, so make sure you make the width of the windows long enough to display ALL digits

1. Start WinDaq, and select (highlight) a channel 

2. Invoke Windaq->View->Add-ons->Magic Meter, and the selected channel will be used as the default channel. 

3. Do not change WinDaq's configurations while WinDaq add-ons are running, or some add-ons may terminate.
