====== OpenScope MZ - Calibration ======

{{ youtube>Bxf24fgrgKM?large }}

The OpenScope MZ uses software calibration to improve measurement accuracy and each OpenScope MZ is calibrated as part of the manufacturing process.  The OpenScope MZ **does not** need to be re-calibrated before each use, however, calibration is recommended before the first use and when changing environments, especially if there is a large temperature variation between environments.  

Calibration tables are saved in the OpenScope MZ flash in one of two locations: **flash** and **SD**.  The **SD** calibration is intended to be overwritten by the user during normal use.  The **flash** calibration is populated during manufacturing but it can also be overwritten.  Calibration data is applied to the instruments when the OpenScope MZ boots.  If the **SD** calibration exists it will be applied.  If not and the **flash** calibration exists it will be applied.  If neither the **SD** nor **flash** calibrations exist the ideal calibration will be applied to the instruments.

==== Calibration Process ====

The OpenScope MZ is calibrated using WaveForms Live.

  - Launch [[http://waveformslive.com/ | WaveForms Live]].
  - [[software:waveforms-live:add-device| Add the OpenScope MZ]] to WaveForms Live. \\ 
  - Click the **More** button on the device card and select **Configure**. \\ \\ {{ reference:test-and-measurement:openscope-mz:waveforms-live-openscope-calibration-4.png |}} \\ \\ {{ reference:test-and-measurement:openscope-mz:waveforms-live-openscope-calibration-5.png |}} \\ \\
  - Under the **Calibration** section click **Calibrate**. \\ \\ {{ reference:test-and-measurement:openscope-mz:waveforms-live-openscope-calibration-6.png |}} \\ \\ 
  - Device specific instructions are provided. 
    - Connect the solid red wire to the solid orange wire.
    - Connect the solid white wire to the solid blue wire.
    - Click **Next** to begin calibration.  \\ \\ {{ reference:test-and-measurement:openscope-mz:waveforms-live-openscope-calibration-7.png |}} \\ \\ 
  - The calibration process takes about 30 seconds.  \\ \\ {{ reference:test-and-measurement:openscope-mz:waveforms-live-openscope-calibration-8.png |}} \\ \\ 
  - The calibration information is displayed.  Select the desired **storage location** (flash is recommended) and click **Save**.  Then click **Done**.  \\ \\ {{ reference:test-and-measurement:openscope-mz:waveforms-live-openscope-calibration-9.png |}} \\ \\ 
  - The new calibration data has been applied to the instrument and will be applied at boot.
