Calculated Channel Recorder (ID=7028)

Obsolete, please use Calculated Channel Recorder II  instead. Due to its status, it is normally installed as a hidden add-on. Please use Windaq Add-on Manager to add it to Windaq's menu if you wish to use it

Use flexible math equation to generate a calculated channel from Windaq-enabled channels in real-time, such as Power =Current & Voltage, a=dV/dt, and polynomial conversion, with RECORDING CAPABILITY

  • To Use This WinDaq Add-ons

    1. Confirm WinDaq 3.16 or higher is installed on your computer

    2. Install WinDaq add-ons.

    3. Start WinDaq, and you will find the WinDaq add-ons integrated into Windaq->View->Add-ons menu 

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

  • Recording capability

    • Add calculated channel to Windaq channels directly

    • Support Pause/Resume

    • Commented Event Marker at resume

    • File size: up to 4GB

  • Performance

  • Chart Features

    • Plot all (up to 16) channels or just the calculated channel

    • To restore full dynamic range of the chart, double click on the min/max notation next to the chart

    • Sizeable Chart

    • Use mouse wheel or buttons to zoom in/out

    • Drag the calculated waveform up/down while Windaq waveforms stay "as is" for reference

  • True math expression with many predefined operators and functions

    • Operators include: +, -, *, /, ^, %, &, |, !, >, >=, <, <=, !=, ==

    • Functions include: abs, floor, hex, round, if, avg, bin, log, sqrt, ceil, log10, sum, max, min, acos, asin, atan, sin, sinh, cos, tan, cosh, tanh

    • To use the reading from a channel, use #n. For example, #0 is the reading from the first enabled channel in Windaq

    • To access the sample rate, use #@.

    • You can use earlier readings to form a more complicated math expression. To do so, add a letter after #, and alphabet order of the letter represents the delay, such as:

      • #0 is the reading from channel 0

      • #A0 is the reading from channel 0, one scan earlier

      • #B1 is the reading from channel 1, two scans earlier

      • Readings from up to 26 scans earlier can be used, for example, #Z0.

      • For example: use ( #0-#A0)*#@, or  #0-#A0, to form a two-point derivative

    • The math equation parser uses standard English (United States) notation without the present of digital grouping symbol, the decimal point must be "." (period) instead of "," (comma). If your Regional and Language Setting is not English (United States), you may need to adjust it

  • Bonus for users with paid registration :

    • No ad-line in the chart

    • No time limit
